Description: A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.

Description: zlib is a Ruby interface for the zlib compression/decompression library. Versions 3.0.0 and below, 3.1.0, 3.1.1, 3.2.0 and 3.2.1 contain a buffer overflow vulnerability in the Zlib::GzipReader. The zstream_buffer_ungets function prepends caller-provided bytes ahead of previously produced output but fails to guarantee the backing Ruby string has enough capacity before the memmove shifts the existing data. This can lead to memory corruption when the buffer length exceeds capacity. This issue has been fixed in versions 3.0.1, 3.1.2 and 3.2.3.

Description: In the Linux kernel, the following vulnerability has been resolved:NFC: digital: Bounds check NFC-A cascade depth in SDD response handlerThe NFC-A anti-collision cascade in digital_in_recv_sdd_res() appends 3or 4 bytes to target->nfcid1 on each round, but the number of cascaderounds is controlled entirely by the peer device. The peer sets thecascade tag in the SDD_RES (deciding 3 vs 4 bytes) and thecascade-incomplete bit in the SEL_RES (deciding whether another roundfollows).ISO 14443-3 limits NFC-A to three cascade levels and target->nfcid1 issized accordingly (NFC_NFCID1_MAXSIZE = 10), but nothing in the driveractually enforces this. This means a malicious peer can keep thecascade running, writing past the heap-allocated nfc_target with eachround.Fix this by rejecting the response when the accumulated UID would exceedthe buffer.Commit e329e71013c9 ("NFC: nci: Bounds check struct nfc_target arrays")fixed similar missing checks against the same field on the NCI path.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: llcp: add missing return after LLCP_CLOSED checksIn nfc_llcp_recv_hdlc() and nfc_llcp_recv_disc(), when the socketstate is LLCP_CLOSED, the code correctly calls release_sock() andnfc_llcp_sock_put() but fails to return. Execution falls through tothe remainder of the function, which calls release_sock() andnfc_llcp_sock_put() again.

That avoids the immediateheader-field OOB read, but the rewrite helpers still walk ACEs based onpdacl->num_aces with no structural validation of the incoming DACL body.A malicious server can return a truncated DACL that still contains aheader, claims one or more ACEs, and then drivereplace_sids_and_copy_aces() or set_chmod_dacl() past the validatedextent while they compare or copy attacker-controlled ACEs.Factor the DACL structural checks into validate_dacl(), extend them tovalidate each ACE against the DACL bounds, and use the shared validatorbefore the chmod/chown rebuild paths. parse_dacl() reuses the samevalidator so the read-side parser and write-side rewrite paths agree onwhat constitutes a well-formed incoming DACL.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: fix heap overflow in NFSv4.0 LOCK replay cacheThe NFSv4.0 replay cache uses a fixed 112-byte inline buffer(rp_ibuf[NFSD4_REPLAY_ISIZE]) to store encoded operation responses.This size was calculated based on OPEN responses and does not accountfor LOCK denied responses, which include the conflicting lock owner asa variable-length field up to 1024 bytes (NFS4_OPAQUE_LIMIT).When a LOCK operation is denied due to a conflict with an existing lockthat has a large owner, nfsd4_encode_operation() copies the full encodedresponse into the undersized replay buffer via read_bytes_from_xdr_buf()with no bounds check. This results in a slab-out-of-bounds write of upto 944 bytes past the end of the buffer, corrupting adjacent heap memory.This can be triggered remotely by an unauthenticated attacker with twocooperating NFSv4.0 clients: one sets a lock with a large owner string,then the other requests a conflicting lock to provoke the denial.We could fix this by increasing NFSD4_REPLAY_ISIZE to allow for a fullopaque, but that would increase the size of every stateowner, when mostlockowners are not that large.Instead, fix this by checking the encoded response length againstNFSD4_REPLAY_ISIZE before copying into the replay buffer. If theresponse is too large, set rp_buflen to 0 to skip caching the replaypayload. The status is still cached, and the client already received thecorrect response on the original request.

Description: gRPC-Go is the Go language implementation of gRPC. Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the `:path` omitted the mandatory leading slash (e.g., `Service/Method` instead of `/Service/Method`). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official `grpc/authz` package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with `/`) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present. This affects gRPC-Go servers that use path-based authorization interceptors, such as the official RBAC implementation in `google.golang.org/grpc/authz` or custom interceptors relying on `info.FullMethod` or `grpc.Method(ctx)`; AND that have a security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule). The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server. The fix in version 1.79.3 ensures that any request with a `:path` that does not start with a leading slash is immediately rejected with a `codes.Unimplemented` error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string. While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods: Use a validating interceptor (recommended mitigation); infrastructure-level normalization; and/or policy hardening.

Description: ERB is a templating system for Ruby. Ruby 2.7.0 (before ERB 2.2.0 was published on rubygems.org) introduced an `@_init` instance variable guard in `ERB#result` and `ERB#run` to prevent code execution when an ERB object is reconstructed via `Marshal.load` (deserialization). However, three other public methods that also evaluate `@src` via `eval()` were not given the same guard: `ERB#def_method`, `ERB#def_module`, and `ERB#def_class`. An attacker who can trigger `Marshal.load` on untrusted data in a Ruby application that has `erb` loaded can use `ERB#def_module` (zero-arg, default parameters) as a code execution sink, bypassing the `@_init` protection entirely. ERB 4.0.3.1, 4.0.4.1, 6.0.1.1, and 6.0.4 patch the issue.

Description: Use-after-free (UAF) was possible in the `lzma.LZMADecompressor`, `bz2.BZ2Decompressor`, and `gzip.GzipFile` when a memory allocation fails with a `MemoryError` and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling pointer in this specific error condition.The vulnerability is only present if the program re-uses decompressor instances across multiple decompression calls even after a `MemoryError` is raised during decompression. Using the helper functions to one-shot decompress data such as `lzma.decompress()`, `bz2.decompress()`, `gzip.decompress()`, and `zlib.decompress()` are not affected as a new decompressor instance is used per call. If the decompressor instance is not re-used after an error condition, this usage is similarly not vulnerable.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/khugepaged: invoke MMU notifiers in shmem/file collapse pathsAny codepath that zaps page table entries must invoke MMU notifiers toensure that secondary MMUs (like KVM) don't keep accessing pages whicharen't mapped anymore. Secondary MMUs don't hold their own references topages that are mirrored over, so failing to notify them can lead to pageuse-after-free.I'm marking this as addressing an issue introduced in commit f3f0e1d2150b("khugepaged: add support of collapse for tmpfs/shmem pages"), but most ofthe security impact of this only came in commit 27e1f8273113 ("khugepaged:enable collapse pmd for pte-mapped THP"), which actually omitted flushesfor the removal of present PTEs, not just for the removal of empty pagetables.

For example, whenthe cryptd queue for AESNI is full (easy to trigger with anartificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueuedto the backlog but still processed. In that case, the async callbackwill also be called twice: first with err == -EINPROGRESS, which itseems we can just ignore, then with err == 0.Compared to Sabrina's original patch this version uses the newtls_*crypt_async_wait() helpers and converts the EBUSY toEINPROGRESS to avoid having to modify all the error handlingpaths.

Description: In the Linux kernel, the following vulnerability has been resolved:bcache: fix cached_dev.sb_bio use-after-free and crashIn our production environment, we have received multiple crash reportsregarding libceph, which have caught our attention:```[6888366.280350] Call Trace:[6888366.280452] blk_update_request+0x14e/0x370[6888366.280561] blk_mq_end_request+0x1a/0x130[6888366.280671] rbd_img_handle_request+0x1a0/0x1b0 [rbd][6888366.280792] rbd_obj_handle_request+0x32/0x40 [rbd][6888366.280903] __complete_request+0x22/0x70 [libceph][6888366.281032] osd_dispatch+0x15e/0xb40 [libceph][6888366.281164] ? inet_recvmsg+0x5b/0xd0[6888366.281272] ? ceph_tcp_recvmsg+0x6f/0xa0 [libceph][6888366.281405] ceph_con_process_message+0x79/0x140 [libceph][6888366.281534] ceph_con_v1_try_read+0x5d7/0xf30 [libceph][6888366.281661] ceph_con_workfn+0x329/0x680 [libceph]```After analyzing the coredump file, we found that the address ofdc->sb_bio has been freed. We know that cached_dev is only freed when itis stopped.Since sb_bio is a part of struct cached_dev, rather than an alloc everytime. If the device is stopped while writing to the superblock, thereleased address will be accessed at endio.This patch hopes to wait for sb_write to complete in cached_dev_free.It should be noted that we analyzed the cause of the problem, then tellall details to the QWEN and adopted the modifications it made.

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: fix use-after-free in ocfs2_fault() when VM_FAULT_RETRYfilemap_fault() may drop the mmap_lock before returning VM_FAULT_RETRY,as documented in mm/filemap.c: "If our return value has VM_FAULT_RETRY set, it's because the mmap_lock may be dropped before doing I/O or by lock_folio_maybe_drop_mmap()."When this happens, a concurrent munmap() can call remove_vma() and freethe vm_area_struct via RCU. The saved 'vma' pointer in ocfs2_fault() thenbecomes a dangling pointer, and the subsequent trace_ocfs2_fault() calldereferences it -- a use-after-free.Fix this by saving ip_blkno as a plain integer before callingfilemap_fault(), and removing vma from the trace event. Sinceip_blkno is copied by value before the lock can be dropped, itremains valid regardless of what happens to the vma or inodeafterward.

Description: An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: Fix use-after-free in l2cap_unregister_userAfter commit ab4eedb790ca ("Bluetooth: L2CAP: Fix corrupted list inhci_chan_del"), l2cap_conn_del() uses conn->lock to protect access toconn->users. However, l2cap_register_user() and l2cap_unregister_user()don't use conn->lock, creating a race condition where these functions canaccess conn->users and conn->hchan concurrently with l2cap_conn_del().This can lead to use-after-free and list corruption bugs, as reportedby syzbot.Fix this by changing l2cap_register_user() and l2cap_unregister_user()to use conn->lock instead of hci_dev_lock(), ensuring consistent lockingfor the l2cap_conn structure.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, ktls: Fix data corruption when using bpf_msg_pop_data() in ktlsWhen sending plaintext data, we initially calculated the correspondingciphertext length. However, if we later reduced the plaintext data lengthvia socket policy, we failed to recalculate the ciphertext length.This results in transmitting buffers containing uninitialized data duringciphertext transmission.This causes uninitialized bytes to be appended after a complete"Application Data" packet, leading to errors on the receiving end whenparsing TLS record.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_ncm: validate minimum block_len in ncm_unwrap_ntb()The block_len read from the host-supplied NTB header is checked againstntb_max but has no lower bound. When block_len is smaller thanopts->ndp_size, the bounds check of: ndp_index > (block_len - opts->ndp_size)will underflow producing a huge unsigned value that ndp_index can neverexceed, defeating the check entirely.The same underflow occurs in the datagram index checks against block_len- opts->dpe_size. With those checks neutered, a malicious USB host canchoose ndp_index and datagram offsets that point past the actualtransfer, and the skb_put_data() copies adjacent kernel memory into thenetwork skb.Fix this by rejecting block lengths that cannot hold at least the NTBheader plus one NDP. This will make block_len - opts->ndp_size andblock_len - opts->dpe_size both well-defined.Commit 8d2b1a1ec9f5 ("CDC-NCM: avoid overflow in sanity checking") fixeda related class of issues on the host side of NCM.

Description: Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.

Description: In the Linux kernel, the following vulnerability has been resolved:netem: fix return value if duplicate enqueue failsThere is a bug in netem_enqueue() introduced bycommit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec")that can lead to a use-after-free.This commit made netem_enqueue() always return NET_XMIT_SUCCESSwhen a packet is duplicated, which can cause the parent qdisc's q.qlento be mistakenly incremented. When this happens qlen_notify() may beskipped on the parent during destruction, leaving a dangling pointerfor some classful qdiscs like DRR.There are two ways for the bug happen:- If the duplicated packet is dropped by rootq->enqueue() and then the original packet is also dropped.- If rootq->enqueue() sends the duplicated packet to a different qdisc and the original packet is dropped.In both cases NET_XMIT_SUCCESS is returned even though no packetsare enqueued at the netem qdisc.The fix is to defer the enqueue of the duplicate packet until afterthe original packet has been guaranteed to return NET_XMIT_SUCCESS.

Description: In the Linux kernel, the following vulnerability has been resolved:tcp/dccp: Don't use timer_pending() in reqsk_queue_unlink().Martin KaFai Lau reported use-after-free [0] in reqsk_timer_handler(). """ We are seeing a use-after-free from a bpf prog attached to trace_tcp_retransmit_synack. The program passes the req->sk to the bpf_sk_storage_get_tracing kernel helper which does check for null before using it. """The commit 83fccfc3940c ("inet: fix potential deadlock inreqsk_queue_unlink()") added timer_pending() in reqsk_queue_unlink() notto call del_timer_sync() from reqsk_timer_handler(), but it introduced asmall race window.Before the timer is called, expire_timers() calls detach_timer(timer, true)to clear timer->entry.pprev and marks it as not pending.If reqsk_queue_unlink() checks timer_pending() just after expire_timers()calls detach_timer(), TCP will miss del_timer_sync(); the reqsk timer willcontinue running and send multiple SYN+ACKs until it expires.The reported UAF could happen if req->sk is close()d earlier than the timerexpiration, which is 63s by default.The scenario would be 1. inet_csk_complete_hashdance() calls inet_csk_reqsk_queue_drop(), but del_timer_sync() is missed 2. reqsk timer is executed and scheduled again 3. req->sk is accept()ed and reqsk_put() decrements rsk_refcnt, but reqsk timer still has another one, and inet_csk_accept() does not clear req->sk for non-TFO sockets 4. sk is close()d 5. reqsk timer is executed again, and BPF touches req->skLet's not use timer_pending() by passing the caller context to__inet_csk_reqsk_queue_drop().Note that reqsk timer is pinned, so the issue does not happen in mostuse cases.

A concurrent dump can still be walking the chain when the error path frees it. 2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly installs the IPv4 hook before IPv6 registration fails. Packets entering nft_do_chain() via the transient IPv4 hook can still be dereferencing chain->blob_gen_X when the error path frees the chain.Add synchronize_rcu() between nft_chain_del() and the chain destroyso that all RCU readers -- both dump threads and in-flight packetevaluation -- have finished before the chain is freed.

Description: In the Linux kernel, the following vulnerability has been resolved:perf/core: Fix refcount bug and potential UAF in perf_mmapSyzkaller reported a refcount_t: addition on 0; use-after-free warningin perf_mmap.The issue is caused by a race condition between a failing mmap() setupand a concurrent mmap() on a dependent event (e.g., using outputredirection).In perf_mmap(), the ring_buffer (rb) is allocated and assigned toevent->rb with the mmap_mutex held. The mutex is then released toperform map_range().If map_range() fails, perf_mmap_close() is called to clean up.However, since the mutex was dropped, another thread attaching tothis event (via inherited events or output redirection) can acquirethe mutex, observe the valid event->rb pointer, and attempt toincrement its reference count. If the cleanup path has alreadydropped the reference count to zero, this results in ause-after-free or refcount saturation warning.Fix this by extending the scope of mmap_mutex to cover themap_range() call. This ensures that the ring buffer initializationand mapping (or cleanup on failure) happens atomically effectively,preventing other threads from accessing a half-initialized ordying ring buffer.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_tables: unconditionally bump set->nelems before insertionIn case that the set is full, a new element gets published then removedwithout waiting for the RCU grace period, while RCU reader can bewalking over it already.To address this issue, add the element transaction even if set is full,but toggle the set_full flag to report -ENFILE so the abort path safelyunwinds the set to its previous state.As for element updates, decrement set->nelems to restore it.A simpler fix is to call synchronize_rcu() in the error path.However, with a large batch adding elements to already maxed-out set,this could cause noticeable slowdown of such batches.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: fix use-after-free in ctnetlink_dump_exp_ct()ctnetlink_dump_exp_ct() stores a conntrack pointer in cb->data for thenetlink dump callback ctnetlink_exp_ct_dump_table(), but drops theconntrack reference immediately after netlink_dump_start(). When thedump spans multiple rounds, the second recvmsg() triggers the dumpcallback which dereferences the now-freed conntrack via nfct_help(ct),leading to a use-after-free on ct->ext.The bug is that the netlink_dump_control has no .start or .donecallbacks to manage the conntrack reference across dump rounds. Otherdump functions in the same file (e.g. ctnetlink_get_conntrack) properlyuse .start/.done callbacks for this purpose.Fix this by adding .start and .done callbacks that hold and release theconntrack reference for the duration of the dump, and move thenfct_help() call after the cb->args[0] early-return check in the dumpcallback to avoid dereferencing ct->ext unnecessarily.

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: Hold net reference for the lifetime of /proc/fs/nfs/exports fdThe /proc/fs/nfs/exports proc entry is created at module initand persists for the module's lifetime. exports_proc_open()captures the caller's current network namespace and storesits svc_export_cache in seq->private, but takes no referenceon the namespace. If the namespace is subsequently torn down(e.g. container destruction after the opener does setns() to adifferent namespace), nfsd_net_exit() calls nfsd_export_shutdown()which frees the cache. Subsequent reads on the still-open fddereference the freed cache_detail, walking a freed hash table.Hold a reference on the struct net for the lifetime of the openfile descriptor. This prevents nfsd_net_exit() from running --and thus prevents nfsd_export_shutdown() from freeing the cache-- while any exports fd is open. cache_detail already storesits net pointer (cd->net, set by cache_create_net()), soexports_release() can retrieve it without additional per-filestorage.

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix fanout UAF in packet_release() via NETDEV_UP race`packet_release()` has a race window where `NETDEV_UP` can re-register asocket into a fanout group's `arr[]` array. The re-registration is notcleaned up by `fanout_release()`, leaving a dangling pointer in the fanoutarray.`packet_release()` does NOT zero `po->num` in its `bind_lock` section.After releasing `bind_lock`, `po->num` is still non-zero and `po->ifindex`still matches the bound device. A concurrent `packet_notifier(NETDEV_UP)`that already found the socket in `sklist` can re-register the hook.For fanout sockets, this re-registration calls `__fanout_link(sk, po)`which adds the socket back into `f->arr[]` and increments `f->num_members`,but does NOT increment `f->sk_ref`.The fix sets `po->num` to zero in `packet_release` while `bind_lock` isheld to prevent NETDEV_UP from linking, preventing the race window.This bug was found following an additional audit with Claude Code basedon CVE-2025-38617.

Description: In the Linux kernel, the following vulnerability has been resolved:smb: client: make use of smbdirect_socket.recv_io.credits.availableThe logic off managing recv credits by counting posted recv_io andgranted credits is racy.That's because the peer might already consumed a credit,but between receiving the incoming recv at the hardwareand processing the completion in the 'recv_done' functionswe likely have a window where we grant credits, whichdon't really exist.So we better have a decicated counter for theavailable credits, which will be incrementedwhen we posted new recv buffers and drained whenwe grant the credits to the peer.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Use scratch field in MMIO fragment to hold small write valuesWhen exiting to userspace to service an emulated MMIO write, copy theto-be-written value to a scratch field in the MMIO fragment if the sizeof the data payload is 8 bytes or less, i.e. can fit in a single chunk,instead of pointing the fragment directly at the source value.This fixes a class of use-after-free bugs that occur when the emulatorinitiates a write using an on-stack, local variable as the source, thewrite splits a page boundary, *and* both pages are MMIO pages. BecauseKVM's ABI only allows for physically contiguous MMIO requests, accessesthat split MMIO pages are separated into two fragments, and are sent touserspace one at a time. When KVM attempts to complete userspace MMIO inresponse to KVM_RUN after the first fragment, KVM will detect the secondfragment and generate a second userspace exit, and reference the on-stackvariable.The issue is most visible if the second KVM_RUN is performed by a separatetask, in which case the stack of the initiating task can show up as trulyfreed data. ================================================================== BUG: KASAN: use-after-free in complete_emulated_mmio+0x305/0x420 Read of size 1 at addr ffff888009c378d1 by task syz-executor417/984 CPU: 1 PID: 984 Comm: syz-executor417 Not tainted 5.10.0-182.0.0.95.h2627.eulerosv2r13.x86_64 #3 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014 Call Trace: dump_stack+0xbe/0xfd print_address_description.constprop.0+0x19/0x170 __kasan_report.cold+0x6c/0x84 kasan_report+0x3a/0x50 check_memory_region+0xfd/0x1f0 memcpy+0x20/0x60 complete_emulated_mmio+0x305/0x420 kvm_arch_vcpu_ioctl_run+0x63f/0x6d0 kvm_vcpu_ioctl+0x413/0xb20 __se_sys_ioctl+0x111/0x160 do_syscall_64+0x30/0x40 entry_SYSCALL_64_after_hwframe+0x67/0xd1 RIP: 0033:0x42477d Code: <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b0 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007faa8e6890e8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00000000004d7338 RCX: 000000000042477d RDX: 0000000000000000 RSI: 000000000000ae80 RDI: 0000000000000005 RBP: 00000000004d7330 R08: 00007fff28d546df R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 00000000004d733c R13: 0000000000000000 R14: 000000000040a200 R15: 00007fff28d54720 The buggy address belongs to the page: page:0000000029f6a428 refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x9c37 flags: 0xfffffc0000000(node=0|zone=1|lastcpupid=0x1fffff) raw: 000fffffc0000000 0000000000000000 ffffea0000270dc8 0000000000000000 raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff888009c37780: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffff888009c37800: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >ffff888009c37880: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ^ ffff888009c37900: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ffff888009c37980: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ==================================================================The bug can also be reproduced with a targeted KVM-Unit-Test by hackingKVM to fill a large on-stack variable in complete_emulated_mmio(), i.e. byoverwrite the data value with garbage.Limit the use of the scratch fields to 8-byte or smaller accesses, and tojust writes, as larger accesses and reads are not affected thanks toimplementation details in the emulator, but add a sanity check to ensurethose details don't change in the future.

Description: In the Linux kernel, the following vulnerability has been resolved:net/packet: fix TOCTOU race on mmap'd vnet_hdr in tpacket_snd()In tpacket_snd(), when PACKET_VNET_HDR is enabled, vnet_hdr pointsdirectly into the mmap'd TX ring buffer shared with userspace. Thekernel validates the header via __packet_snd_vnet_parse() but thenre-reads all fields later in virtio_net_hdr_to_skb(). A concurrentuserspace thread can modify the vnet_hdr fields between validationand use, bypassing all safety checks.The non-TPACKET path (packet_snd()) already correctly copies vnet_hdrto a stack-local variable. All other vnet_hdr consumers in the kernel(tun.c, tap.c, virtio_net.c) also use stack copies. The TPACKET TXpath is the only caller of virtio_net_hdr_to_skb() that reads directlyfrom user-controlled shared memory.Fix this by copying vnet_hdr from the mmap'd ring buffer to astack-local variable before validation and use, consistent with theapproach used in packet_snd() and all other callers.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_ecm: Fix net_device lifecycle with device_moveThe net_device is allocated during function instance creation andregistered during the bind phase with the gadget device as its sysfsparent. When the function unbinds, the parent device is destroyed, butthe net_device survives, resulting in dangling sysfs symlinks: console:/ # ls -l /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0 console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls: .../gadget.0/net/usb0: No such file or directoryUse device_move() to reparent the net_device between the gadget devicetree and /sys/devices/virtual across bind and unbind cycles. During thefinal unbind, calling device_move(NULL) moves the net_device to thevirtual device tree before the gadget device is destroyed. On rebinding,device_move() reparents the device back under the new gadget, ensuringproper sysfs topology and power management ordering.To maintain compatibility with legacy composite drivers (e.g., multi.c),the bound flag is used to indicate whether the network device is sharedand pre-registered during the legacy driver's bind phase.

Description: In the Linux kernel, the following vulnerability has been resolved:atm: lec: fix use-after-free in sock_def_readable()A race condition exists between lec_atm_close() setting priv->lecdto NULL and concurrent access to priv->lecd in send_to_lecd(),lec_handle_bridge(), and lec_atm_send(). When the socket is freedvia RCU while another thread is still using it, a use-after-freeoccurs in sock_def_readable() when accessing the socket's wait queue.The root cause is that lec_atm_close() clears priv->lecd withoutany synchronization, while callers dereference priv->lecd withoutany protection against concurrent teardown.Fix this by converting priv->lecd to an RCU-protected pointer:- Mark priv->lecd as __rcu in lec.h- Use rcu_assign_pointer() in lec_atm_close() and lecd_attach() for safe pointer assignment- Use rcu_access_pointer() for NULL checks that do not dereference the pointer in lec_start_xmit(), lec_push(), send_to_lecd() and lecd_attach()- Use rcu_read_lock/rcu_dereference/rcu_read_unlock in send_to_lecd(), lec_handle_bridge() and lec_atm_send() to safely access lecd- Use rcu_assign_pointer() followed by synchronize_rcu() in lec_atm_close() to ensure all readers have completed before proceeding. This is safe since lec_atm_close() is called from vcc_release() which holds lock_sock(), a sleeping lock.- Remove the manual sk_receive_queue drain from lec_atm_close() since vcc_destroy_socket() already drains it after lec_atm_close() returns.v2: Switch from spinlock + sock_hold/put approach to RCU to properly fix the race. The v1 spinlock approach had two issues pointed out by Eric Dumazet: 1. priv->lecd was still accessed directly after releasing the lock instead of using a local copy. 2. The spinlock did not prevent packets being queued after lec_atm_close() drains sk_receive_queue since timer and workqueue paths bypass netif_stop_queue().Note: Syzbot patch testing was attempted but the test VM terminated unexpectedly with "Connection to localhost closed by remote host", likely due to a QEMU AHCI emulation issue unrelated to this fix. Compile testing with "make W=1 net/atm/lec.o" passes cleanly.

Description: When sed is invoked with both -i (in-place edit) and --follow-symlinks, the function open_next_file() performs two separate, non-atomic filesystem operations on the same path: 1. resolves symlink to its target and stores the resolved path for determining when output is written,2. opens the original symlink path (not the resolved one) to read the file. Between these two calls there is a race window. If an attacker atomically replaces the symlink with a different target during that window, sed will: read content from the new (attacker-chosen) symlink target and write the processed result to the path recorded in step 1. This can lead to arbitrary file overwrite with attacker-controlled content in the context of the sed process.This issue was fixed in version 4.10.

Description: In the Linux kernel, the following vulnerability has been resolved:l2tp: prevent possible tunnel refcount underflowWhen a session is created, it sets a backpointer to its tunnel. Whenthe session refcount drops to 0, l2tp_session_free drops the tunnelrefcount if session->tunnel is non-NULL. However, session->tunnel isset in l2tp_session_create, before the tunnel refcount is incrementedby l2tp_session_register, which leaves a small window wheresession->tunnel is non-NULL when the tunnel refcount hasn't beenbumped.Moving the assignment to l2tp_session_register is trivial butl2tp_session_create calls l2tp_session_set_header_len which usessession->tunnel to get the tunnel's encap. Add an encap arg tol2tp_session_set_header_len to avoid using session->tunnel.If l2tpv3 sessions have colliding IDs, it is possible forl2tp_v3_session_get to race with l2tp_session_register and fetch asession which doesn't yet have session->tunnel set.

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: fix integer underflow in chain modeThe jumbo_frm() chain-mode implementation unconditionally computes len = nopaged_len - bmax;where nopaged_len = skb_headlen(skb) (linear bytes only) and bmax isBUF_SIZE_8KiB or BUF_SIZE_2KiB. However, the caller stmmac_xmit()decides to invoke jumbo_frm() based on skb->len (total length includingpage fragments): is_jumbo = stmmac_is_jumbo_frm(priv, skb->len, enh_desc);When a packet has a small linear portion (nopaged_len <= bmax) but alarge total length due to page fragments (skb->len > bmax), thesubtraction wraps as an unsigned integer, producing a huge len value(~0xFFFFxxxx). This causes the while (len != 0) loop to executehundreds of thousands of iterations, passing skb->data + bmax * ipointers far beyond the skb buffer to dma_map_single(). On IOMMU-lessSoCs (the typical deployment for stmmac), this maps arbitrary kernelmemory to the DMA engine, constituting a kernel memory disclosure andpotential memory corruption from hardware.Fix this by introducing a buf_len local variable clamped tomin(nopaged_len, bmax). Computing len = nopaged_len - buf_len is thenalways safe: it is zero when the linear portion fits within a singledescriptor, causing the while (len != 0) loop to be skipped naturally,and the fragment loop in stmmac_xmit() handles page fragments afterward.

Description: In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user. NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature. Because this behavior surprised some users, sudo 1.8.30 introduced an option to enable/disable this behavior with the default being disabled. However, this does not change the fact that sudo was behaving as intended, and as documented, in earlier versions

Description: In the Linux kernel, the following vulnerability has been resolved:tracing: Free buffers when a used dynamic event is removedAfter 65536 dynamic events have been added and removed, the "type" fieldof the event then uses the first type number that is available (notcurrently used by other events). A type number is the identifier of thebinary blobs in the tracing ring buffer (known as events) to map them tologic that can parse the binary blob.The issue is that if a dynamic event (like a kprobe event) is traced andis in the ring buffer, and then that event is removed (because it isdynamic, which means it can be created and destroyed), if another dynamicevent is created that has the same number that new event's logic onparsing the binary blob will be used.To show how this can be an issue, the following can crash the kernel: # cd /sys/kernel/tracing # for i in `seq 65536`; do echo 'p:kprobes/foo do_sys_openat2 $arg1:u32' > kprobe_events # doneFor every iteration of the above, the writing to the kprobe_events willremove the old event and create a new one (with the same format) andincrease the type number to the next available on until the type numberreaches over 65535 which is the max number for the 16 bit type. After itreaches that number, the logic to allocate a new number simply looks forthe next available number. When an dynamic event is removed, that numberis then available to be reused by the next dynamic event created. That is,once the above reaches the max number, the number assigned to the event inthat loop will remain the same.Now that means deleting one dynamic event and created another will reusethe previous events type number. This is where bad things can happen.After the above loop finishes, the kprobes/foo event which reads thedo_sys_openat2 function call's first parameter as an integer. # echo 1 > kprobes/foo/enable # cat /etc/passwd > /dev/null # cat trace cat-2211 [005] .... 2007.849603: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849620: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849838: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 cat-2211 [005] .... 2007.849880: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196 # echo 0 > kprobes/foo/enableNow if we delete the kprobe and create a new one that reads a string: # echo 'p:kprobes/foo do_sys_openat2 +0($arg2):string' > kprobe_eventsAnd now we can the trace: # cat trace sendmail-1942 [002] ..... 530.136320: foo: (do_sys_openat2+0x0/0x240) arg1= cat-2046 [004] ..... 530.930817: foo: (do_sys_openat2+0x0/0x240) arg1="������������������������������������������������������������������������������������������������" cat-2046 [004] ..... 530.930961: foo: (do_sys_openat2+0x0/0x240) arg1="������������������������������������������������������������������������������������������������" cat-2046 [004] ..... 530.934278: foo: (do_sys_openat2+0x0/0x240) arg1="������������������������������������������������������������������������������������������������" cat-2046 [004] ..... 530.934563: foo: (do_sys_openat2+0x0/0x240) arg1="���������������������������������������---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix out-of-bounds access in ops_initnet_alloc_generic is called by net_alloc, which is called without anylocking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. Itis read twice, first to allocate an array, then to set s.len, which islater used to limit the bounds of the array access.It is possible that the array is allocated and another thread isregistering a new pernet ops, increments max_gen_ptrs, which is then usedto set s.len with a larger than allocated length for the variable array.Fix it by reading max_gen_ptrs only once in net_alloc_generic. Ifmax_gen_ptrs is later incremented, it will be caught in net_assign_generic.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: provide locking for v4_end_graceWriting to v4_end_grace can race with server shutdown and result inmemory being accessed after it was freed - reclaim_str_hashtbl inparticularly.We cannot hold nfsd_mutex across the nfsd4_end_grace() call as that isheld while client_tracking_op->init() is called and that can wait foran upcall to nfsdcltrack which can write to v4_end_grace, resulting in adeadlock.nfsd4_end_grace() is also called by the landromat work queue and thisdoesn't require locking as server shutdown will stop the work and waitfor it before freeing anything that nfsd4_end_grace() might access.However, we must be sure that writing to v4_end_grace doesn't restartthe work item after shutdown has already waited for it. For this weadd a new flag protected with nn->client_lock. It is set only while itis safe to make client tracking calls, and v4_end_grace only scheduleswork while the flag is set with the spinlock held.So this patch adds a nfsd_net field "client_tracking_active" which isset as described. Another field "grace_end_forced", is set whenv4_end_grace is written. After this is set, and providingclient_tracking_active is set, the laundromat is scheduled.This "grace_end_forced" field bypasses other checks for whether thegrace period has finished.This resolves a race which can result in use-after-free.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix out-of-bounds write in trie_get_next_key()trie_get_next_key() allocates a node stack with size trie->max_prefixlen,while it writes (trie->max_prefixlen + 1) nodes to the stack when it hasfull paths from the root to leaves. For example, consider a trie withmax_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with.prefixlen = 8 make 9 nodes be written on the node stack with size 8.

Description: net-tools is a collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system. Inn versions up to and including 2.10, the Linux network utilities (like ifconfig) from the net-tools package do not properly validate the structure of /proc files when showing interfaces. `get_name()` in `interface.c` copies interface labels from `/proc/net/dev` into a fixed 16-byte stack buffer without bounds checking, leading to possible arbitrary code execution or crash. The known attack path does not require privilege but also does not provide privilege escalation in this scenario. A patch is available and expected to be part of version 2.20.

Description: Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been patched in version 9.1.2132.

Description: Vim is an open source, command line text editor. Prior to 9.2.0357, A command injection vulnerability exists in Vim's tag file processing. When resolving a tag, the filename field from the tags file is passed through wildcard expansion to resolve environment variables and wildcards. If the filename field contains backtick syntax (e.g., `command`), Vim executes the embedded command via the system shell with the full privileges of the running user.

Description: There is a defect in the CPython “tarfile” module affecting the “TarFile” extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives.

Description: The API function `ssh_get_hexa()` is vulnerable, when 0-lenghtinput is provided to this function. This function is used internallyin `ssh_get_fingerprint_hash()` and `ssh_print_hexa()` (deprecated),which is vulnerable to the same input (length is provided by thecalling application).The function is also used internally in the gssapi code for loggingthe OIDs received by the server during GSSAPI authentication. Thiscould be triggered remotely, when the server allows GSSAPI authenticationand logging verbosity is set at least to SSH_LOG_PACKET (3). Thiscould cause self-DoS of the per-connection daemon process.

Description: In the Linux kernel, the following vulnerability has been resolved:net: add xmit recursion limit to tunnel xmit functionsTunnel xmit functions (iptunnel_xmit, ip6tunnel_xmit) lack their ownrecursion limit. When a bond device in broadcast mode has GRE tapinterfaces as slaves, and those GRE tunnels route back through thebond, multicast/broadcast traffic triggers infinite recursion betweenbond_xmit_broadcast() and ip_tunnel_xmit()/ip6_tnl_xmit(), causingkernel stack overflow.The existing XMIT_RECURSION_LIMIT (8) in the no-qdisc path is notsufficient because tunnel recursion involves route lookups and full IPoutput, consuming much more stack per level. Use a lower limit of 4(IP_TUNNEL_RECURSION_LIMIT) to prevent overflow.Add recursion detection using dev_xmit_recursion helpers directly iniptunnel_xmit() and ip6tunnel_xmit() to cover all IPv4/IPv6 tunnelpaths including UDP encapsulated tunnels (VXLAN, Geneve, etc.).Move dev_xmit_recursion helpers from net/core/dev.h to public headerinclude/linux/netdevice.h so they can be used by tunnel code.

Description: Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to the same domain (e.g., "h.local" as a CNAME for "h.local"). This causes unbounded recursion in the lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: L2CAP: Fix ERTM re-init and zero pdu_len infinite loopl2cap_config_req() processes CONFIG_REQ for channels in BT_CONNECTEDstate to support L2CAP reconfiguration (e.g. MTU changes). However,since both CONF_INPUT_DONE and CONF_OUTPUT_DONE are already set fromthe initial configuration, the reconfiguration path falls through tol2cap_ertm_init(), which re-initializes tx_q, srej_q, srej_list, andretrans_list without freeing the previous allocations and setschan->sdu to NULL without freeing the existing skb. This leaks allpreviously allocated ERTM resources.Additionally, l2cap_parse_conf_req() does not validate the minimumvalue of remote_mps derived from the RFC max_pdu_size option. A zerovalue propagates to l2cap_segment_sdu() where pdu_len becomes zero,causing the while loop to never terminate since len is neverdecremented, exhausting all available memory.Fix the double-init by skipping l2cap_ertm_init() andl2cap_chan_ready() when the channel is already in BT_CONNECTED state,while still allowing the reconfiguration parameters to be updatedthrough l2cap_parse_conf_req(). Also add a pdu_len zero check inl2cap_segment_sdu() as a safeguard.

Description: In the Linux kernel, the following vulnerability has been resolved:usbip: validate number_of_packets in usbip_pack_ret_submit()When a USB/IP client receives a RET_SUBMIT response,usbip_pack_ret_submit() unconditionally overwritesurb->number_of_packets from the network PDU. This value issubsequently used as the loop bound in usbip_recv_iso() andusbip_pad_iso() to iterate over urb->iso_frame_desc[], a flexiblearray whose size was fixed at URB allocation time based on the*original* number_of_packets from the CMD_SUBMIT.A malicious USB/IP server can set number_of_packets in the responseto a value larger than what was originally submitted, causing a heapout-of-bounds write when usbip_recv_iso() writes tourb->iso_frame_desc[i] beyond the allocated region.KASAN confirmed this with kernel 7.0.0-rc5: BUG: KASAN: slab-out-of-bounds in usbip_recv_iso+0x46a/0x640 Write of size 4 at addr ffff888106351d40 by task vhci_rx/69 The buggy address is located 0 bytes to the right of allocated 320-byte region [ffff888106351c00, ffff888106351d40)The server side (stub_rx.c) and gadget side (vudc_rx.c) alreadyvalidate number_of_packets in the CMD_SUBMIT path since commitsc6688ef9f297 ("usbip: fix stub_rx: harden CMD_SUBMIT path to handlemalicious input") and b78d830f0049 ("usbip: fix vudc_rx: hardenCMD_SUBMIT path to handle malicious input"). The server side validatesagainst USBIP_MAX_ISO_PACKETS because no URB exists yet at that point.On the client side we have the original URB, so we can use the tighterbound: the response must not exceed the original number_of_packets.This mirrors the existing validation of actual_length againsttransfer_buffer_length in usbip_recv_xbuff(), which checks theresponse value against the original allocation size.Kelvin Mbogo's series ("usb: usbip: fix integer overflow inusbip_recv_iso()", v2) hardens the receive-side functions themselves;this patch complements that work by catching the bad value at itssource -- in usbip_pack_ret_submit() before the overwrite -- andusing the tighter per-URB allocation bound rather than the globalUSBIP_MAX_ISO_PACKETS limit.Fix this by checking rpdu->number_of_packets againsturb->number_of_packets in usbip_pack_ret_submit() before theoverwrite. On violation, clamp to zero so that usbip_recv_iso() andusbip_pad_iso() safely return early.

Description: In the Linux kernel, the following vulnerability has been resolved:batman-adv: reject oversized global TT response buffersbatadv_tt_prepare_tvlv_global_data() builds the allocation length for aglobal TT response in 16-bit temporaries. When a remote originatoradvertises a large enough global TT, the TT payload length plus the VLANheader offset can exceed 65535 and wrap before kmalloc().The full-table response path still uses the original TT payload length whenit fills tt_change, so the wrapped allocation is too small andbatadv_tt_prepare_tvlv_global_data() writes past the end of the heap objectbefore the later packet-size check runs.Fix this by rejecting TT responses whose TVLV value length cannot fit inthe 16-bit TVLV payload length field.

Description: Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, the RSS notifier allows .. path traversal in notify-recipient-uri (e.g., rss:///../job.cache), letting a remote IPP client write RSS XML bytes outside CacheDir/rss (anywhere that is lp-writable). In particular, because CacheDir is group-writable by default (typically root:lp and mode 0770), the notifier (running as lp) can replace root-managed state files via temp-file + rename(). This PoC clobbers CacheDir/job.cache with RSS XML, and after restarting cupsd the scheduler fails to parse the job cache and previously queued jobs disappear. At time of publication, there are no publicly available patches.

Description: In the Linux kernel, the following vulnerability has been resolved:nvme: fix a possible use-after-free in controller reset during loadUnlike .queue_rq, in .submit_async_event drivers may not check the ctrlreadiness for AER submission. This may lead to a use-after-freecondition that was observed with nvme-tcp.The race condition may happen in the following scenario:1. driver executes its reset_ctrl_work2. -> nvme_stop_ctrl - flushes ctrl async_event_work3. ctrl sends AEN which is received by the host, which in turn schedules AEN handling4. teardown admin queue (which releases the queue socket)5. AEN processed, submits another AER, calling the driver to submit6. driver attempts to send the cmd==> use-after-freeIn order to fix that, add ctrl state check to validate the ctrlis actually able to accept the AER submission.This addresses the above race in controller resets because the driverduring teardown should:1. change ctrl state to RESETTING2. flush async_event_work (as well as other async work elements)So after 1,2, any other AER command will find thectrl state to be RESETTING and bail out without submitting the AER.

Description: In the Linux kernel, the following vulnerability has been resolved:regulator: core: Use different devices for resource allocation and DT lookupFollowing by the below discussion, there's the potential UAF issuebetween regulator and mfd.https://lore.kernel.org/all/20221128143601.1698148-1-yangyingliang@huawei.com/From the analysis of YingliangCPU A |CPU Bmt6370_probe() | devm_mfd_add_devices() | |mt6370_regulator_probe() | regulator_register() | //allocate init_data and add it to devres | regulator_of_get_init_data()i2c_unregister_device() | device_del() | devres_release_all() | // init_data is freed | release_nodes() | | // using init_data causes UAF | regulator_register()It's common to use mfd core to create child device for the regulator.In order to do the DT lookup for init data, the child that registeredthe regulator would pass its parent as the parameter. And this causesinit data resource allocated to its parent, not itself. The issue happenwhen parent device is going to release and regulator core is still doingsome operation of init data constraint for the regulator of child device.To fix it, this patch expand 'regulator_register' API to use thedifferent devices for init data allocation and DT lookup.

Description: In the Linux kernel, the following vulnerability has been resolved:mm: call the security_mmap_file() LSM hook in remap_file_pages()The remap_file_pages syscall handler calls do_mmap() directly, whichdoesn't contain the LSM security check. And if the process has calledpersonality(READ_IMPLIES_EXEC) before and remap_file_pages() is called forRW pages, this will actually result in remapping the pages to RWX,bypassing a W^X policy enforced by SELinux.So we should check prot by security_mmap_file LSM hook in theremap_file_pages syscall handler before do_mmap() is called.

Description: In the Linux kernel, the following vulnerability has been resolved:loop: Avoid updating block size under exclusive ownerSyzbot came up with a reproducer where a loop device block size ischanged underneath a mounted filesystem. This causes a mismatch betweenthe block device block size and the block size stored in the superblockcausing confusion in various places such as fs/buffer.c. The particularissue triggered by syzbot was a warning in __getblk_slow() due torequested buffer size not matching block device block size.Fix the problem by getting exclusive hold of the loop device to changeits block size. This fails if somebody (such as filesystem) has alreadyan exclusive ownership of the block device and thus prevents modifyingthe loop device under some exclusive owner which doesn't expect it.

Description: In the Linux kernel, the following vulnerability has been resolved:net: sched: avoid qdisc_reset_all_tx_gt() vs dequeue race for lockless qdiscsWhen shrinking the number of real tx queues,netif_set_real_num_tx_queues() calls qdisc_reset_all_tx_gt() to flushqdiscs for queues which will no longer be used.qdisc_reset_all_tx_gt() currently serializes qdisc_reset() withqdisc_lock(). However, for lockless qdiscs, the dequeue path isserialized by qdisc_run_begin/end() using qdisc->seqlock instead, soqdisc_reset() can run concurrently with __qdisc_run() and free skbswhile they are still being dequeued, leading to UAF.This can easily be reproduced on e.g. virtio-net by imposing heavytraffic while frequently changing the number of queue pairs: iperf3 -ub0 -c $peer -t 0 & while :; do ethtool -L eth0 combined 1 ethtool -L eth0 combined 2 doneWith KASAN enabled, this leads to reports like: BUG: KASAN: slab-use-after-free in __qdisc_run+0x133f/0x1760 ...

Description: In the Linux kernel, the following vulnerability has been resolved:net: mana: fix use-after-free in mana_hwc_destroy_channel() by reordering teardownA potential race condition exists in mana_hwc_destroy_channel() wherehwc->caller_ctx is freed before the HWC's Completion Queue (CQ) andEvent Queue (EQ) are destroyed. This allows an in-flight CQ interrupthandler to dereference freed memory, leading to a use-after-free orNULL pointer dereference in mana_hwc_handle_resp().mana_smc_teardown_hwc() signals the hardware to stop but does notsynchronize against IRQ handlers already executing on other CPUs. TheIRQ synchronization only happens in mana_hwc_destroy_cq() viamana_gd_destroy_eq() -> mana_gd_deregister_irq(). Since this runsafter kfree(hwc->caller_ctx), a concurrent mana_hwc_rx_event_handler()can dereference freed caller_ctx (and rxq->msg_buf) inmana_hwc_handle_resp().Fix this by reordering teardown to reverse-of-creation order: destroythe TX/RX work queues and CQ/EQ before freeing hwc->caller_ctx. Thisensures all in-flight interrupt handlers complete before the memory theyaccess is freed.

Description: In the Linux kernel, the following vulnerability has been resolved:team: fix header_ops type confusion with non-Ethernet portsSimilar to commit 950803f72547 ("bonding: fix type confusion inbond_setup_by_slave()") team has the same class of header_ops typeconfusion.For non-Ethernet ports, team_setup_by_port() copies port_dev->header_opsdirectly. When the team device later calls dev_hard_header() ordev_parse_header(), these callbacks can run with the team net_deviceinstead of the real lower device, so netdev_priv(dev) is interpreted asthe wrong private type and can crash.The syzbot report shows a crash in bond_header_create(), but the rootcause is in team: the topology is gre -> bond -> team, and team callsthe inherited header_ops with its own net_device instead of the lowerdevice, so bond_header_create() receives a team device and interpretsnetdev_priv() as bonding private data, causing a type confusion crash.Fix this by introducing team header_ops wrappers for create/parse,selecting a team port under RCU, and calling the lower device callbackswith port->dev, so each callback always sees the correct net_devicecontext.Also pass the selected lower device to the lower parse callback, sorecursion is bounded in stacked non-Ethernet topologies and parsecallbacks always run with the correct device context.

Description: In the Linux kernel, the following vulnerability has been resolved:driver core: enforce device_lock for driver_match_device()Currently, driver_match_device() is called from three sites. One site(__device_attach_driver) holds device_lock(dev), but the other two(bind_store and __driver_attach) do not. This inconsistency means thatbus match() callbacks are not guaranteed to be called with the lockheld.Fix this by introducing driver_match_device_locked(), which guaranteesholding the device lock using a scoped guard. Replace the unlocked callsin bind_store() and __driver_attach() with this new helper. Also add alock assertion to driver_match_device() to enforce this guarantee.This consistency also fixes a known race condition. The driver_overrideimplementation relies on the device_lock, so the missing lock led to theuse-after-free (UAF) reported in Bugzilla for buses using this field.Stress testing the two newly locked paths for 24 hours withCONFIG_PROVE_LOCKING and CONFIG_LOCKDEP enabled showed no UAF recurrenceand no lockdep warnings.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Prevent lpfc_debugfs_lockstat_write() buffer overflowA static code analysis tool flagged the possibility of buffer overflow whenusing copy_from_user() for a debugfs entry.Currently, it is possible that copy_from_user() copies more bytes than whatwould fit in the mybuf char array. Add a min() restriction check betweensizeof(mybuf) - 1 and nbytes passed from the userspace buffer to protectagainst buffer overflow.

Description: In the Linux kernel, the following vulnerability has been resolved:ftruncate: pass a signed offsetThe old ftruncate() syscall, using the 32-bit off_t misses a signextension when called in compat mode on 64-bit architectures. As aresult, passing a negative length accidentally succeeds in truncatingto file size between 2GiB and 4GiB.Changing the type of the compat syscall to the signed compat_off_tchanges the behavior so it instead returns -EINVAL.The native entry point, the truncate() syscall and the correspondingloff_t based variants are all correct already and do not sufferfrom this mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:net: dsa: properly keep track of conduit referenceProblem description-------------------DSA has a mumbo-jumbo of reference handling of the conduit net deviceand its kobject which, sadly, is just wrong and doesn't make sense.There are two distinct problems.1. The OF path, which uses of_find_net_device_by_node(), never releases the elevated refcount on the conduit's kobject. Nominally, the OF and non-OF paths should result in objects having identical reference counts taken, and it is already suspicious that dsa_dev_to_net_device() has a put_device() call which is missing in dsa_port_parse_of(), but we can actually even verify that an issue exists. With CONFIG_DEBUG_KOBJECT_RELEASE=y, if we run this command "before" and "after" applying this patch:(unbind the conduit driver for net device eno2)echo 0000:00:00.2 > /sys/bus/pci/drivers/fsl_enetc/unbindwe see these lines in the output diff which appear only with the patchapplied:kobject: 'eno2' (ffff002009a3a6b8): kobject_release, parent 0000000000000000 (delayed 1000)kobject: '109' (ffff0020099d59a0): kobject_release, parent 0000000000000000 (delayed 1000)2. After we find the conduit interface one way (OF) or another (non-OF), it can get unregistered at any time, and DSA remains with a long-lived, but in this case stale, cpu_dp->conduit pointer. Holding the net device's underlying kobject isn't actually of much help, it just prevents it from being freed (but we never need that kobject directly). What helps us to prevent the net device from being unregistered is the parallel netdev reference mechanism (dev_hold() and dev_put()).Actually we actually use that netdev tracker mechanism implicitly onuser ports since commit 2f1e8ea726e9 ("net: dsa: link interfaces withthe DSA master to get rid of lockdep warnings"), via netdev_upper_dev_link().But time still passes at DSA switch probe time between the initialof_find_net_device_by_node() code and the user port creation time, timeduring which the conduit could unregister itself and DSA wouldn't knowabout it.So we have to run of_find_net_device_by_node() under rtnl_lock() toprevent that from happening, and release the lock only with the netdevtracker having acquired the reference.Do we need to keep the reference until dsa_unregister_switch() /dsa_switch_shutdown()?1: Maybe yes. A switch device will still be registered even if all user ports failed to probe, see commit 86f8b1c01a0a ("net: dsa: Do not make user port errors fatal"), and the cpu_dp->conduit pointers remain valid. I haven't audited all call paths to see whether they will actually use the conduit in lack of any user port, but if they do, it seems safer to not rely on user ports for that reference.2. Definitely yes. We support changing the conduit which a user port is associated to, and we can get into a situation where we've moved all user ports away from a conduit, thus no longer hold any reference to it via the net device tracker. But we shouldn't let it go nonetheless - see the next change in relation to dsa_tree_find_first_conduit() and LAG conduits which disappear. We have to be prepared to return to the physical conduit, so the CPU port must explicitly keep another reference to it. This is also to say: the user ports and their CPU ports may not always keep a reference to the same conduit net device, and both are needed.As for the conduit's kobject for the /sys/class/net/ entry, we don'tcare about it, we can release it as soon as we hold the net deviceobject itself.History and blame attribution-----------------------------The code has been refactored so many times, it is very difficult tofollow and properly attribute a blame, but I'll try to make a shorthistory which I hope to be correct.We have two distinct probing paths:- one for OF, introduced in 2016 i---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:gve: Fix stats report corruption on queue count changeThe driver and the NIC share a region in memory for stats reporting.The NIC calculates its offset into this region based on the total sizeof the stats region and the size of the NIC's stats.When the number of queues is changed, the driver's stats region isresized. If the queue count is increased, the NIC can write pastthe end of the allocated stats region, causing memory corruption.If the queue count is decreased, there is a gap between the driverand NIC stats, leading to incorrect stats reporting.This change fixes the issue by allocating stats region with maximumsize, and the offset calculation for NIC stats is changed to matchwith the calculation of the NIC.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: libertas: fix use-after-free in lbs_free_adapter()The lbs_free_adapter() function uses timer_delete() (non-synchronous)for both command_timer and tx_lockup_timer before the structure isfreed. This is incorrect because timer_delete() does not wait forany running timer callback to complete.If a timer callback is executing when lbs_free_adapter() is called,the callback will access freed memory since lbs_cfg_free() frees thecontaining structure immediately after lbs_free_adapter() returns.Both timer callbacks (lbs_cmd_timeout_handler and lbs_tx_lockup_handler)access priv->driver_lock, priv->cur_cmd, priv->dev, and other fields,which would all be use-after-free violations.Use timer_delete_sync() instead to ensure any running timer callbackhas completed before returning.This bug was introduced in commit 8f641d93c38a ("libertas: detect TXlockups and reset hardware") where del_timer() was used instead ofdel_timer_sync() in the cleanup path. The command_timer has had thesame issue since the driver was first written.

Description: In the Linux kernel, the following vulnerability has been resolved:drbd: fix "LOGIC BUG" in drbd_al_begin_io_nonblock()Even though we check that we "should" be able to do lc_get_cumulative()while holding the device->al_lock spinlock, it may still fail,if some other code path decided to do lc_try_lock() with bad timing.If that happened, we logged "LOGIC BUG for enr=...",but still did not return an error.The rest of the code now assumed that this request has referencesfor the relevant activity log extents.The implcations are that during an active resync, mutual exclusivity ofresync versus application IO is not guaranteed. And a potential crashat this point may not realizs that these extents could have been targetof in-flight IO and would need to be resynced just in case.Also, once the request completes, it will give up activity log references itdoes not even hold, which will trigger a BUG_ON(refcnt == 0) in lc_put().Fix:Do not crash the kernel for a condition that is harmless during normaloperation: also catch "e->refcnt == 0", not only "e == NULL"when being noisy about "al_complete_io() called on inactive extent %u\n".And do not try to be smart and "guess" whether something will work, thenbe surprised when it does not.Deal with the fact that it may or may not work. If it does not, remember apossible "partially in activity log" state (only possible for requests thatcross extent boundaries), and return an error code fromdrbd_al_begin_io_nonblock().A latter call for the same request will then resume from where we left off.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: radiotap: reject radiotap with unknown bitsThe radiotap parser is currently only used with the radiotapnamespace (not with vendor namespaces), but if the undefinedfield 18 is used, the alignment/size is unknown as well. Inthis case, iterator->_next_ns_data isn't initialized (it'sonly set for skipping vendor namespaces), and syzbot pointsout that we later compare against this uninitialized value.Fix this by moving the rejection of unknown radiotap fieldsdown to after the in-namespace lookup, so it will really useiterator->_next_ns_data only for vendor namespaces, even incase undefined fields are present.

Description: In the Linux kernel, the following vulnerability has been resolved:parisc: Revise __get_user() to probe user read accessBecause of the way read access support is implemented, read accessinterruptions are only triggered at privilege levels 2 and 3. Thekernel executes at privilege level 0, so __get_user() never triggersa read access interruption (code 26). Thus, it is currently possiblefor user code to access a read protected address via a system call.Fix this by probing read access rights at privilege level 3 (PRIV_USER)and setting __gu_err to -EFAULT (-14) if access isn't allowed.Note the cmpiclr instruction does a 32-bit compare because COND macrodoesn't work inside asm.

Description: In the Linux kernel, the following vulnerability has been resolved:net: usb: cdc_ncm: add ndpoffset to NDP16 nframes bounds checkcdc_ncm_rx_verify_ndp16() validates that the NDP header and its DPEentries fit within the skb. The first check correctly accounts forndpoffset: if ((ndpoffset + sizeof(struct usb_cdc_ncm_ndp16)) > skb_in->len)but the second check omits it: if ((sizeof(struct usb_cdc_ncm_ndp16) + ret * (sizeof(struct usb_cdc_ncm_dpe16))) > skb_in->len)This validates the DPE array size against the total skb length as ifthe NDP were at offset 0, rather than at ndpoffset. When the NDP isplaced near the end of the NTB (large wNdpIndex), the DPE entries canextend past the skb data buffer even though the check passes.cdc_ncm_rx_fixup() then reads out-of-bounds memory when iteratingthe DPE array.Add ndpoffset to the nframes bounds check and use struct_size_t() toexpress the NDP-plus-DPE-array size more clearly.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: log new dentries when logging parent dir of a conflicting inodeIf we log the parent directory of a conflicting inode, we are not loggingthe new dentries of the directory, so when we finish we have the parentdirectory's inode marked as logged but we did not log its new dentries.As a consequence if the parent directory is explicitly fsynced later andit does not have any new changes since we logged it, the fsync is a no-opand after a power failure the new dentries are missing.Example scenario: $ mkdir foo $ sync $rmdir foo $ mkdir dir1 $ mkdir dir2 # A file with the same name and parent as the directory we just deleted # and was persisted in a past transaction. So the deleted directory's # inode is a conflicting inode of this new file's inode. $ touch foo $ ln foo dir2/link # The fsync on dir2 will log the parent directory (".") because the # conflicting inode (deleted directory) does not exists anymore, but it # it does not log its new dentries (dir1). $ xfs_io -c "fsync" dir2 # This fsync on the parent directory is no-op, since the previous fsync # logged it (but without logging its new dentries). $ xfs_io -c "fsync" .
# After log replay dir1 is missing.Fix this by ensuring we log new dir dentries whenever we log the parentdirectory of a no longer existing conflicting inode.A test case for fstests will follow soon.

Description: In the Linux kernel, the following vulnerability has been resolved:udp: Fix wildcard bind conflict check when using hash2When binding a udp_sock to a local address and port, UDP usestwo hashes (udptable->hash and udptable->hash2) for collisiondetection. The current code switches to "hash2" whenhslot->count > 10."hash2" is keyed by local address and local port."hash" is keyed by local port only.The issue can be shown in the following bind sequence (pseudo code):bind(fd1, "[fd00::1]:8888")bind(fd2, "[fd00::2]:8888")bind(fd3, "[fd00::3]:8888")bind(fd4, "[fd00::4]:8888")bind(fd5, "[fd00::5]:8888")bind(fd6, "[fd00::6]:8888")bind(fd7, "[fd00::7]:8888")bind(fd8, "[fd00::8]:8888")bind(fd9, "[fd00::9]:8888")bind(fd10, "[fd00::10]:8888")/* Correctly return -EADDRINUSE because "hash" is used * instead of "hash2". udp_lib_lport_inuse() detects the * conflict. */bind(fail_fd, "[::]:8888")/* After one more socket is bound to "[fd00::11]:8888", * hslot->count exceeds 10 and "hash2" is used instead. */bind(fd11, "[fd00::11]:8888")bind(fail_fd, "[::]:8888") /* succeeds unexpectedly */The same issue applies to the IPv4 wildcard address "0.0.0.0"and the IPv4-mapped wildcard address "::ffff:0.0.0.0". Forexample, if there are existing sockets bound to"192.168.1.[1-11]:8888", then binding "0.0.0.0:8888" or"[::ffff:0.0.0.0]:8888" can also miss the conflict whenhslot->count > 10.TCP inet_csk_get_port() already has the correct check ininet_use_bhash2_on_bind(). Rename it toinet_use_hash2_on_bind() and move it to inet_hashtables.hso udp.c can reuse it in this fix.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete()A broken/bored/mean USB host can overflow the skb_shared_info->frags[]array on a Linux gadget exposing a Phonet function by sending anunbounded sequence of full-page OUT transfers.pn_rx_complete() finalizes the skb only when req->actual < req->length,where req->length is set to PAGE_SIZE by the gadget. If the host alwayssends exactly PAGE_SIZE bytes per transfer, fp->rx.skb will never bereset and each completion will add another fragment viaskb_add_rx_frag(). Once nr_frags exceeds MAX_SKB_FRAGS (default 17),subsequent frag stores overwrite memory adjacent to the shinfo on theheap.Drop the skb and account a length error when the frag limit is reached,matching the fix applied in t7xx by commit f0813bcd2d9d ("net: wwan:t7xx: fix potential skb->frags overflow in RX path").

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: f_eem: Fix net_device lifecycle with device_moveThe net_device is allocated during function instance creation andregistered during the bind phase with the gadget device as its sysfsparent. When the function unbinds, the parent device is destroyed, butthe net_device survives, resulting in dangling sysfs symlinks:console:/ # ls -l /sys/class/net/usb0lrwxrwxrwx ... /sys/class/net/usb0 ->/sys/devices/platform/.../gadget.0/net/usb0console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0ls: .../gadget.0/net/usb0: No such file or directoryUse device_move() to reparent the net_device between the gadget devicetree and /sys/devices/virtual across bind and unbind cycles. During thefinal unbind, calling device_move(NULL) moves the net_device to thevirtual device tree before the gadget device is destroyed. On rebinding,device_move() reparents the device back under the new gadget, ensuringproper sysfs topology and power management ordering.To maintain compatibility with legacy composite drivers (e.g., multi.c),the bound flag is used to indicate whether the network device is sharedand pre-registered during the legacy driver's bind phase.

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: caiaq: fix stack out-of-bounds read in init_cardThe loop creates a whitespace-stripped copy of the card shortnamewhere `len < sizeof(card->id)` is used for the bounds check. Sincesizeof(card->id) is 16 and the local id buffer is also 16 bytes,writing 16 non-space characters fills the entire buffer,overwriting the terminating nullbyte.When this non-null-terminated string is later passed tosnd_card_set_id() -> copy_valid_id_string(), the function scansforward with `while (*nid && ...)` and reads past the end of thestack buffer, reading the contents of the stack.A USB device with a product name containing many non-ASCII, non-spacecharacters (e.g. multibyte UTF-8) will reliably trigger this as follows: BUG: KASAN: stack-out-of-bounds in copy_valid_id_string sound/core/init.c:696 [inline] BUG: KASAN: stack-out-of-bounds in snd_card_set_id_no_lock+0x698/0x74c sound/core/init.c:718The off-by-one has been present since commit bafeee5b1f8d ("ALSA:snd_usb_caiaq: give better shortname") from June 2009 (v2.6.31-rc1),which first introduced this whitespace-stripping loop. The originalcode never accounted for the null terminator when bounding the copy.Fix this by changing the loop bound to `sizeof(card->id) - 1`,ensuring at least one byte remains as the null terminator.

Description: In the Linux kernel, the following vulnerability has been resolved:firmware_loader: Block path traversalMost firmware names are hardcoded strings, or are constructed from fairlyconstrained format strings where the dynamic parts are just some hexnumbers or such.However, there are a couple codepaths in the kernel where firmware filenames contain string components that are passed through from a device orsemi-privileged userspace; the ones I could find (not counting interfacesthat require root privileges) are: - lpfc_sli4_request_firmware_update() seems to construct the firmware filename from "ModelName", a string that was previously parsed out of some descriptor ("Vital Product Data") in lpfc_fill_vpd() - nfp_net_fw_find() seems to construct a firmware filename from a model name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I think parses some descriptor that was read from the device. (But this case likely isn't exploitable because the format string looks like "netronome/nic_%s", and there shouldn't be any *folders* starting with "netronome/nic_". The previous case was different because there, the "%s" is *at the start* of the format string.) - module_flash_fw_schedule() is reachable from the ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is enough to pass the privilege check), and takes a userspace-provided firmware name. (But I think to reach this case, you need to have CAP_NET_ADMIN over a network namespace that a special kind of ethernet device is mapped into, so I think this is not a viable attack path in practice.)Fix it by rejecting any firmware names containing ".." path components.For what it's worth, I went looking and haven't found any USB devicedrivers that use the firmware loader dangerously.

Prior to 9.2.0316, a command injection vulnerability in Vim's netbeans interface allows a malicious netbeans server to execute arbitrary Ex commands when Vim connects to it, via unsanitized strings in the defineAnnoType and specialKeys protocol messages. This vulnerability is fixed in 9.2.0316.

Description: OpenSSL 1.1.1 introduced a rewritten random number generator (RNG). This was intended to include protection in the event of a fork() system call in order to ensure that the parent and child processes did not share the same RNG state. However this protection was not being used in the default case. A partial mitigation for this issue is that the output from a high precision timer is mixed into the RNG state so the likelihood of a parent and child process sharing state is significantly reduced. If an application already calls OPENSSL_init_crypto() explicitly using OPENSSL_INIT_ATFORK then this problem does not occur at all. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c).

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV socketsTCP_SYN_RECV state is really special, it is only used bycross-syn connections, mostly used by fuzzers.In the following crash [1], syzbot managed to trigger a divideby zero in tcp_rcv_space_adjust()A socket makes the following state transitions,without ever calling tcp_init_transfer(),meaning tcp_init_buffer_space() is also not called. TCP_CLOSEconnect() TCP_SYN_SENT TCP_SYN_RECVshutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1To fix this issue, change tcp_shutdown() to notperform a TCP_SYN_RECV -> TCP_FIN_WAIT1 transition,which makes no sense anyway.When tcp_rcv_state_process() later changes socket statefrom TCP_SYN_RECV to TCP_ESTABLISH, then look atsk->sk_shutdown to finally enter TCP_FIN_WAIT1 state,and send a FIN packet from a sane socket state.This means tcp_send_fin() can now be called from BHcontext, and must use GFP_ATOMIC allocations.[1]divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 1 PID: 5084 Comm: syz-executor358 Not tainted 6.9.0-rc6-syzkaller-00022-g98369dccd2f8 #0Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 03/27/2024 RIP: 0010:tcp_rcv_space_adjust+0x2df/0x890 net/ipv4/tcp_input.c:767Code: e3 04 4c 01 eb 48 8b 44 24 38 0f b6 04 10 84 c0 49 89 d5 0f 85 a5 03 00 00 41 8b 8e c8 09 00 00 89 e8 29 c8 48 0f af c3 31 d2 <48> f7 f1 48 8d 1c 43 49 8d 96 76 08 00 00 48 89 d0 48 c1 e8 03 48RSP: 0018:ffffc900031ef3f0 EFLAGS: 00010246RAX: 0c677a10441f8f42 RBX: 000000004fb95e7e RCX: 0000000000000000RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000RBP: 0000000027d4b11f R08: ffffffff89e535a4 R09: 1ffffffff25e6ab7R10: dffffc0000000000 R11: ffffffff8135e920 R12: ffff88802a9f8d30R13: dffffc0000000000 R14: ffff88802a9f8d00 R15: 1ffff1100553f2daFS: 00005555775c0380(0000) GS:ffff8880b9500000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f1155bf2304 CR3: 000000002b9f2000 CR4: 0000000000350ef0Call Trace: tcp_recvmsg_locked+0x106d/0x25a0 net/ipv4/tcp.c:2513 tcp_recvmsg+0x25d/0x920 net/ipv4/tcp.c:2578 inet6_recvmsg+0x16a/0x730 net/ipv6/af_inet6.c:680 sock_recvmsg_nosec net/socket.c:1046 [inline] sock_recvmsg+0x109/0x280 net/socket.c:1068 ____sys_recvmsg+0x1db/0x470 net/socket.c:2803 ___sys_recvmsg net/socket.c:2845 [inline] do_recvmmsg+0x474/0xae0 net/socket.c:2939 __sys_recvmmsg net/socket.c:3018 [inline] __do_sys_recvmmsg net/socket.c:3041 [inline] __se_sys_recvmmsg net/socket.c:3034 [inline] __x64_sys_recvmmsg+0x199/0x250 net/socket.c:3034 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf5/0x240 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7fRIP: 0033:0x7faeb6363db9Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 c1 17 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007ffcc1997168 EFLAGS: 00000246 ORIG_RAX: 000000000000012bRAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007faeb6363db9RDX: 0000000000000001 RSI: 0000000020000bc0 RDI: 0000000000000005RBP: 0000000000000000 R08: 0000000000000000 R09: 000000000000001cR10: 0000000000000122 R11: 0000000000000246 R12: 0000000000000000R13: 0000000000000000 R14: 0000000000000001 R15: 0000000000000001

Description: In GnuPG through 2.4.8, if a signed message has \f at the end of a plaintext line, an adversary can construct a modified message that places additional text after the signed material, such that signature verification of the modified message succeeds (although an "invalid armor" message is printed during verification).

Description: In MIT Kerberos 5 (aka krb5) before 1.22.3, there is an integer underflow and resultant out-of-bounds read if an application calls gss_accept_sec_context() on a system with a NegoEx mechanism registered in /etc/gss/mech. An unauthenticated remote attacker can trigger this, possibly causing the process to terminate in parse_message.

Description: lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: core: Prevent USB core invalid event buffer address accessThis commit addresses an issue where the USB core could access aninvalid event buffer address during runtime suspend, potentially causingSMMU faults and other memory issues in Exynos platforms. The problemarises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address.To prevent this hardware quirk on Exynos platforms, this commit ensuresthat the event buffer address is not cleared by software when the USBcore is active during runtime suspend by checking its status beforeclearing the buffer address.

Description: In the Linux kernel, the following vulnerability has been resolved:padata: Fix pd UAF once and for allThere is a race condition/UAF in padata_reorder that goes backto the initial commit. A reference count is taken at the startof the process in padata_do_parallel, and released at the end inpadata_serial_worker.This reference count is (and only is) required for padata_replaceto function correctly. If padata_replace is never called thenthere is no issue.In the function padata_reorder which serves as the core of padata,as soon as padata is added to queue->serial.list, and the associatedspin lock released, that padata may be processed and the referencecount on pd would go away.Fix this by getting the next padata before the squeue->serial lockis released.In order to make this possible, simplify padata_reorder by onlycalling it once the next padata arrives.

Description: pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation.

Description: Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash.A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets.

Description: Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1406, when processing nested tuples during Vim9 script import operations, an error during evaluation can trigger a double-free in Vim's internal typed value (typval_T) management. Specifically, the clear_tv() function may attempt to free memory that has already been deallocated, due to improper lifetime handling in the handle_import / ex_import code paths. The vulnerability can only be triggered if a user explicitly opens and executes a specially crafted Vim script. This issue has been patched in version 9.1.1406.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_netem: fix out-of-bounds access in packet corruptionIn netem_enqueue(), the packet corruption logic usesget_random_u32_below(skb_headlen(skb)) to select an index formodifying skb->data. When an AF_PACKET TX_RING sends fully non-linearpackets over an IPIP tunnel, skb_headlen(skb) evaluates to 0.Passing 0 to get_random_u32_below() takes the variable-ceil slow pathwhich returns an unconstrained 32-bit random integer. Using thisunconstrained value as an offset into skb->data results in anout-of-bounds memory access.Fix this by verifying skb_headlen(skb) is non-zero before attemptingto corrupt the linear data area. Fully non-linear packets will silentlybypass the corruption logic.

Description: A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.

Description: In the Linux kernel, the following vulnerability has been resolved:ip6_tunnel: clear skb2->cb[] in ip4ip6_err()Oskar Kjos reported the following problem.ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was writtenby the IPv6 receive path as struct inet6_skb_parm. icmp_send() passesIPCB(skb2) to __ip_options_echo(), which interprets that cb[] regionas struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoffat offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rrvalue. __ip_options_echo() then reads optlen from attacker-controlledpacket data at sptr[rr+1] and copies that many bytes into dopt->__data,a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).To fix this we clear skb2->cb[], as suggested by Oskar Kjos.Also add minimal IPv4 header validation (version == 4, ihl >= 5).

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()Sashiko AI-review observed: In ip6_err_gen_icmpv6_unreach(), the skb is an outer IPv4 ICMP error packet where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2 and passed to icmp6_send(), it uses IP6CB(skb2). IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm. The cipso offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm at offset 18. If an attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao would be a non-zero offset. Inside icmp6_send(), mip6_addr_swap() is called and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO). This would scan the inner, attacker-controlled IPv6 packet starting at that offset, potentially returning a fake TLV without checking if the remaining packet length can hold the full 18-byte struct ipv6_destopt_hao. Could mip6_addr_swap() then perform a 16-byte swap that extends past the end of the packet data into skb_shared_info? Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and ip6ip6_err() to prevent this?This patch implements the first suggestion.I am not sure if ip6ip6_err() needs to be changed.A separate patch would be better anyway.

Description: Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters (instead of using a named curve). In those cases it is possible that such a group does not have the cofactor present. This can occur even where all the parameters match a known named curve. If such a curve is used then OpenSSL falls back to non-side channel resistant code paths which may result in full key recovery during an ECDSA signature operation. In order to be vulnerable an attacker would have to have the ability to time the creation of a large number of signatures where explicit parameters with no co-factor present are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL 1.1.0l (Affected 1.1.0-1.1.0k).

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock when cloning inline extents and using qgroupsThere are a few exceptional cases where cloning an inline extent needs tocopy the inline extent data into a page of the destination inode.When this happens, we end up starting a transaction while having a dirtypage for the destination inode and while having the range locked in thedestination's inode iotree too. Because when reserving metadata spacefor a transaction we may need to flush existing delalloc in case there isnot enough free space, we have a mechanism in place to prevent a deadlock,which was introduced in commit 3d45f221ce627d ("btrfs: fix deadlock whencloning inline extent and low on free metadata space").However when using qgroups, a transaction also reserves metadata qgroupspace, which can also result in flushing delalloc in case there is notenough available space at the moment. When this happens we deadlock, sinceflushing delalloc requires locking the file range in the inode's iotreeand the range was already locked at the very beginning of the cloneoperation, before attempting to start the transaction.When this issue happens, stack traces like the following are reported: [72747.556262] task:kworker/u81:9 state:D stack: 0 pid: 225 ppid: 2 flags:0x00004000 [72747.556268] Workqueue: writeback wb_workfn (flush-btrfs-1142) [72747.556271] Call Trace: [72747.556273] __schedule+0x296/0x760 [72747.556277] schedule+0x3c/0xa0 [72747.556279] io_schedule+0x12/0x40 [72747.556284] __lock_page+0x13c/0x280 [72747.556287] ? generic_file_readonly_mmap+0x70/0x70 [72747.556325] extent_write_cache_pages+0x22a/0x440 [btrfs] [72747.556331] ? __set_page_dirty_nobuffers+0xe7/0x160 [72747.556358] ? set_extent_buffer_dirty+0x5e/0x80 [btrfs] [72747.556362] ? update_group_capacity+0x25/0x210 [72747.556366] ? cpumask_next_and+0x1a/0x20 [72747.556391] extent_writepages+0x44/0xa0 [btrfs] [72747.556394] do_writepages+0x41/0xd0 [72747.556398] __writeback_single_inode+0x39/0x2a0 [72747.556403] writeback_sb_inodes+0x1ea/0x440 [72747.556407] __writeback_inodes_wb+0x5f/0xc0 [72747.556410] wb_writeback+0x235/0x2b0 [72747.556414] ? get_nr_inodes+0x35/0x50 [72747.556417] wb_workfn+0x354/0x490 [72747.556420] ? newidle_balance+0x2c5/0x3e0 [72747.556424] process_one_work+0x1aa/0x340 [72747.556426] worker_thread+0x30/0x390 [72747.556429] ? create_worker+0x1a0/0x1a0 [72747.556432] kthread+0x116/0x130 [72747.556435] ? kthread_park+0x80/0x80 [72747.556438] ret_from_fork+0x1f/0x30 [72747.566958] Workqueue: btrfs-flush_delalloc btrfs_work_helper [btrfs] [72747.566961] Call Trace: [72747.566964] __schedule+0x296/0x760 [72747.566968] ? finish_wait+0x80/0x80 [72747.566970] schedule+0x3c/0xa0 [72747.566995] wait_extent_bit.constprop.68+0x13b/0x1c0 [btrfs] [72747.566999] ? finish_wait+0x80/0x80 [72747.567024] lock_extent_bits+0x37/0x90 [btrfs] [72747.567047] btrfs_invalidatepage+0x299/0x2c0 [btrfs] [72747.567051] ? find_get_pages_range_tag+0x2cd/0x380 [72747.567076] __extent_writepage+0x203/0x320 [btrfs] [72747.567102] extent_write_cache_pages+0x2bb/0x440 [btrfs] [72747.567106] ? update_load_avg+0x7e/0x5f0 [72747.567109] ? enqueue_entity+0xf4/0x6f0 [72747.567134] extent_writepages+0x44/0xa0 [btrfs] [72747.567137] ? enqueue_task_fair+0x93/0x6f0 [72747.567140] do_writepages+0x41/0xd0 [72747.567144] __filemap_fdatawrite_range+0xc7/0x100 [72747.567167] btrfs_run_delalloc_work+0x17/0x40 [btrfs] [72747.567195] btrfs_work_helper+0xc2/0x300 [btrfs] [72747.567200] process_one_work+0x1aa/0x340 [72747.567202] worker_thread+0x30/0x390 [72747.567205] ? create_worker+0x1a0/0x1a0 [72747.567208] kthread+0x116/0x130 [72747.567211] ? kthread_park+0x80/0x80 [72747.567214] ret_from_fork+0x1f/0x30 [72747.569686] task:fsstress state:D stack: ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: bridge: fix vlan tunnel dst null pointer dereferenceThis patch fixes a tunnel_dst null pointer dereference due to locklessaccess in the tunnel egress path. When deleting a vlan tunnel thetunnel_dst pointer is set to NULL without waiting a grace period (i.e.while it's still usable) and packets egressing are dereferencing itwithout checking. Use READ/WRITE_ONCE to annotate the lockless use oftunnel_id, use RCU for accessing tunnel_dst and make sure it is readonly once and checked in the egress path. The dst is already properly RCUprotected so we don't need to do anything fancy than to make suretunnel_id and tunnel_dst are read only once and checked in the egress path.

Description: In the Linux kernel, the following vulnerability has been resolved:mac80211-hwsim: fix late beacon hrtimer handlingThomas explained in https://lore.kernel.org/r/87mtoeb4hb.ffs@tglxthat our handling of the hrtimer here is wrong: If the timer fireslate (e.g. due to vCPU scheduling, as reported by Dmitry/syzbot)then it tries to actually rearm the timer at the next deadline,which might be in the past already: 1 2 3 N N+1 | | | ... | | ^ intended to fire here (1) ^ next deadline here (2) ^ actually fired hereThe next time it fires, it's later, but will still try to schedulefor the next deadline (now 3), etc. until it catches up with N,but that might take a long time, causing stalls etc.Now, all of this is simulation, so we just have to fix it, butnote that the behaviour is wrong even per spec, since there's novalue then in sending all those beacons unaligned - they should bealigned to the TBTT (1, 2, 3, ... in the picture), and if we're abit (or a lot) late, then just resume at that point.Therefore, change the code to use hrtimer_forward_now() which willensure that the next firing of the timer would be at N+1 (in thepicture), i.e. the next interval point after the current time.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix abort logic in btrfs_replace_file_extentsError injection testing uncovered a case where we'd end up with acorrupt file system with a missing extent in the middle of a file. Thisoccurs because the if statement to decide if we should abort is wrong.The only way we would abort in this case is if we got a ret !=-EOPNOTSUPP and we called from the file clone code. However theprealloc code uses this path too. Instead we need to abort if there isan error, and the only error we _don't_ abort on is -EOPNOTSUPP and onlyif we came from the clone file code.

We try to create an inline extent for them, but we fail when trying to insert the inline extent with -ENOSPC (at cow_file_range_inline()) - since this is not critical, we fallback to non-inline mode (back to cow_file_range()), reserve extents---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix a memleak when uncloning an skb dst and its metadataWhen uncloning an skb dst and its associated metadata, a newdst+metadata is allocated and later replaces the old one in the skb.This is helpful to have a non-shared dst+metadata attached to a specificskb.The issue is the uncloned dst+metadata is initialized with a refcount of1, which is increased to 2 before attaching it to the skb. Whentun_dst_unclone returns, the dst+metadata is only referenced from asingle place (the skb) while its refcount is 2. Its refcount will neverdrop to 0 (when the skb is consumed), leading to a memory leak.Fix this by removing the call to dst_hold in tun_dst_unclone, as thedst+metadata refcount is already 1.

Description: In the Linux kernel, the following vulnerability has been resolved:swiotlb: fix info leak with DMA_FROM_DEVICEThe problem I'm addressing was discovered by the LTP test coveringcve-2018-1000204.A short description of what happens follows:1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV and a corresponding dxferp. The peculiar thing about this is that TUR is not reading from the device.2) In sg_start_req() the invocation of blk_rq_map_user() effectively bounces the user-space buffer. As if the device was to transfer into it. Since commit a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in sg_build_indirect()") we make sure this first bounce buffer is allocated with GFP_ZERO.3) For the rest of the story we keep ignoring that we have a TUR, so the device won't touch the buffer we prepare as if the we had a DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device and the buffer allocated by SG is mapped by the function virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here scatter-gather and not scsi generics). This mapping involves bouncing via the swiotlb (we need swiotlb to do virtio in protected guest like s390 Secure Execution, or AMD SEV).4) When the SCSI TUR is done, we first copy back the content of the second (that is swiotlb) bounce buffer (which most likely contains some previous IO data), to the first bounce buffer, which contains all zeros. Then we copy back the content of the first bounce buffer to the user-space buffer.5) The test case detects that the buffer, which it zero-initialized, ain't all zeros and fails.One can argue that this is an swiotlb problem, because without swiotlbwe leak all zeros, and the swiotlb should be transparent in a sense thatit does not affect the outcome (if all other participants are wellbehaved).Copying the content of the original buffer into the swiotlb buffer isthe only way I can think of to make swiotlb transparent in suchscenarios. So let's do just that if in doubt, but allow the driverto tell us that the whole mapped buffer is going to be overwritten,in which case we can preserve the old behavior and avoid the performanceimpact of the extra bounce.

Description: In the Linux kernel, the following vulnerability has been resolved:rtc: cmos: Fix event handler registration ordering issueBecause acpi_install_fixed_event_handler() enables the eventautomatically on success, it is incorrect to call it before thehandler routine passed to it is ready to handle events.Unfortunately, the rtc-cmos driver does exactly the incorrect thingby calling cmos_wake_setup(), which passes rtc_handler() toacpi_install_fixed_event_handler(), before cmos_do_probe(), becausertc_handler() uses dev_get_drvdata() to get to the cmos objectpointer and the driver data pointer is only populated incmos_do_probe().This leads to a NULL pointer dereference in rtc_handler() on bootif the RTC fixed event happens to be active at the init time.To address this issue, change the initialization ordering of thedriver so that cmos_wake_setup() is always called after a successfulcmos_do_probe() call.While at it, change cmos_pnp_probe() to call cmos_do_probe() afterthe initial if () statement used for computing the IRQ argument tobe passed to cmos_do_probe() which is cleaner than calling it ineach branch of that if () (local variable "irq" can be of type int,because it is passed to that function as an argument of type int).Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not checkACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger numberof systems, because previously it only affected systems withACPI_FADT_LOW_POWER_S0 set, but it is present regardless of thatcommit.

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()As comment of pci_get_domain_bus_and_slot() says, it returnsa pci device with refcount increment, when finish using it,the caller must decrement the reference count by callingpci_dev_put(). So call it after using to avoid refcount leak.

Description: In the Linux kernel, the following vulnerability has been resolved:net: xfrm: unexport __init-annotated xfrm4_protocol_init()EXPORT_SYMBOL and __init is a bad combination because the .init.textsection is freed up after the initialization. Hence, modules cannotuse symbols annotated __init. The access to a freed symbol may end upwith kernel panic.modpost used to detect it, but it has been broken for a decade.Recently, I fixed modpost so it started to warn it again, then thisshowed up in linux-next builds.There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOLI chose the latter for this case because the only in-tree call-site,net/ipv4/xfrm4_policy.c is never compiled as modular.(CONFIG_XFRM is boolean)

In normalcase, aead_request_complete() will be called in pcrypt_aead_serial and thereturn err is 0 for padata_do_parallel. But, when pinst->flags isPADATA_RESET, the return err is -EBUSY for padata_do_parallel, and itwon't call aead_request_complete(). Therefore, test_aead_vec_cfg willhung at wait_for_completion(&wait->completion), which will causehungtask.The problem comes as following:(padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return errIn order to resolve the problem, we replace the return err -EBUSY with-EAGAIN, which means parallel_data is changing, and the caller should callit again.v3:remove retry and just change the return err.v2:introduce padata_try_do_parallel() in pcrypt_aead_encrypt andpcrypt_aead_decrypt to solve the hungtask.

Description: In the Linux kernel, the following vulnerability has been resolved:padata: Fix refcnt handling in padata_free_shell()In a high-load arm64 environment, the pcrypt_aead01 test in LTP can leadto system UAF (Use-After-Free) issues. Due to the lengthy analysis ofthe pcrypt_aead01 function call, I'll describe the problem scenariousing a simplified model:Suppose there's a user of padata named `user_function` that adheres tothe padata requirement of calling `padata_free_shell` after `serial()`has been invoked, as demonstrated in the following code:```cstruct request { struct padata_priv padata; struct completion *done;};void parallel(struct padata_priv *padata) { do_something();}void serial(struct padata_priv *padata) { struct request *request = container_of(padata, struct request, padata); complete(request->done);}void user_function() { DECLARE_COMPLETION(done) padata->parallel = parallel; padata->serial = serial; padata_do_parallel(); wait_for_completion(&done); padata_free_shell();}```In the corresponding padata.c file, there's the following code:```cstatic void padata_serial_worker(struct work_struct *serial_work) { ... cnt = 0; while (!list_empty(&local_list)) { ... padata->serial(padata); cnt++; } local_bh_enable(); if (refcount_sub_and_test(cnt, &pd->refcnt)) padata_free_pd(pd);}```Because of the high system load and the accumulation of unexecutedsoftirq at this moment, `local_bh_enable()` in padata takes longerto execute than usual. Subsequently, when accessing `pd->refcnt`,`pd` has already been released by `padata_free_shell()`, resultingin a UAF issue with `pd->refcnt`.The fix is straightforward: add `refcount_dec_and_test` before calling`padata_free_pd` in `padata_free_shell`.

Description: In the Linux kernel, the following vulnerability has been resolved:hwrng: virtio - Fix race on data_avail and actual dataThe virtio rng device kicks off a new entropy request whenever thedata available reaches zero. When a new request occurs at the endof a read operation, that is, when the result of that request isonly needed by the next reader, then there is a race between thewriting of the new data and the next reader.This is because there is no synchronisation whatsoever between thewriter and the reader.Fix this by writing data_avail with smp_store_release and readingit with smp_load_acquire when we first enter read. The subsequentreads are safe because they're either protected by the first loadacquire, or by the completion mechanism.Also remove the redundant zeroing of data_idx in random_recv_done(data_idx must already be zero at this point) and data_avail inrequest_entropy (ditto).

Description: In the Linux kernel, the following vulnerability has been resolved:xen: speed up grant-table reclaimWhen a grant entry is still in use by the remote domain, Linux must putit on a deferred list. Normally, this list is very short, becausethe PV network and block protocols expect the backend to unmap the grantfirst. However, Qubes OS's GUI protocol is subject to the constraintsof the X Window System, and as such winds up with the frontend unmappingthe window first. As a result, the list can grow very large, resultingin a massive memory leak and eventual VM freeze.To partially solve this problem, make the number of entries that the VMwill attempt to free at each iteration tunable. The default is still10, but it can be overridden via a module parameter.This is Cc: stable because (when combined with appropriate userspacechanges) it fixes a severe performance and stability problem for QubesOS users.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: typec: bus: verify partner exists in typec_altmode_attentionSome usb hubs will negotiate DisplayPort Alt mode with the devicebut will then negotiate a data role swap after entering the altmode. The data role swap causes the device to unregister all altmodes, however the usb hub will still send Attention messageseven after failing to reregister the Alt Mode. type_altmode_attentioncurrently does not verify whether or not a device's altmode partnerexists, which results in a NULL pointer error when dereferencingthe typec_altmode and typec_altmode_ops belonging to the altmodepartner.Verify the presence of a device's altmode partner before sendingthe Attention message to the Alt Mode driver.

Description: In the Linux kernel, the following vulnerability has been resolved:fs/xattr: missing fdput() in fremovexattr error pathIn the Linux kernel, the fremovexattr() syscall calls fdget() to acquire afile reference but returns early without calling fdput() whenstrncpy_from_user() fails on the name argument. In multi-threaded processeswhere fdget() takes the slow path, this permanently leaks onefile reference per call, pinning the struct file and associated kernelobjects in memory. An unprivileged local user can exploit this to causekernel memory exhaustion. The issue was inadvertently fixed by commita71874379ec8 ("xattr: switch to CLASS(fd)").

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: act_mirred: use the backlog for mirred ingressThe test Davide added in commit ca22da2fbd69 ("act_mirred: use the backlogfor nested calls to mirred ingress") hangs our testing VMs every 10 or soruns, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported bylockdep.The problem as previously described by Davide (see Link) is thatif we reverse flow of traffic with the redirect (egress -> ingress)we may reach the same socket which generated the packet. And we maystill be holding its socket lock. The common solution to such deadlocksis to put the packet in the Rx backlog, rather than run the Rx pathinline. Do that for all egress -> ingress reversals, not just oncewe started to nest mirred calls.In the past there was a concern that the backlog indirection willlead to loss of error reporting / less accurate stats. But the currentworkaround does not seem to address the issue.

IOW, we skb->data gets "adjusted" by a huge value.The negative value is returned because skb->head and skb->data distance ismore than 64k and skb->network_header (u16) has wrapped around.The bug is in the ip_tunnel infrastructure, which can causedev->needed_headroom to increment ad infinitum.The syzkaller reproducer consists of packets getting routed via a gretunnel, and route of gre encapsulated packets pointing at another (ipip)tunnel. The ipip encapsulation finds gre0 as next output device.This results in the following pattern:1). First packet is to be sent out via gre0.Route lookup found an output device, ipip0.2).ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the futureoutput device, rt.dev->needed_headroom (ipip0).3).ip output / start_xmit moves skb on to ipip0. which runs the samecode path again (xmit recursion).4).Routing step for the post-gre0-encap packet finds gre0 as output deviceto use for ipip0 encapsulated packet.tunl0->needed_headroom is then incremented based on the (already bumped)gre0 device headroom.This repeats for every future packet:gre0->needed_headroom gets inflated because previous packets' ipip0 stepincremented rt->dev (gre0) headroom, and ipip0 incremented because gre0needed_headroom was increased.For each subsequent packet, gre/ipip0->needed_headroom grows untilpost-expand-head reallocations result in a skb->head/data distance ofmore than 64k.Once that happens, skb->network_header (u16) wraps around whenpskb_expand_head tries to make sure that skb_network_offset() is unchangedafter the headroom expansion/reallocation.After this skb_network_offset(skb) returns a different (and negative)result post headroom expansion.The next trip to neigh layer (or anything else that would __skb_pull thenetwork header) makes skb->data point to a memory location outsideskb->head area.v2: Cap the needed_headroom update to an arbitarily chosen upperlimit toprevent perpetual increase instead of dropping the headroom incrementcompletely.

It is dropped only when the last fragment is processedor when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received.However, the NCI device may be deallocated before that which leads to skbleak.As by design the rx_data_reassembly skb is bound to the NCI device andnothing prevents the device to be freed before the skb is processed insome way and cleaned, free it on the NCI device cleanup.Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Gifting a reference to theassociated VM prevents the workqueue callback from dereferencing freedvCPU/VM memory, but does not prevent the KVM module from being unloadedbefore the callback completes.Drop the misguided VM refcount gifting, as calling kvm_put_kvm() fromasync_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue willresult in deadlock. async_pf_execute() can't return until kvm_put_kvm()finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes: WARNING: CPU: 8 PID: 251 at virt/kvm/kvm_main.c:1435 kvm_put_kvm+0x2d/0x320 [kvm] Modules linked in: vhost_net vhost vhost_iotlb tap kvm_intel kvm irqbypass CPU: 8 PID: 251 Comm: kworker/8:1 Tainted: G W 6.6.0-rc1-e7af8d17224a-x86/gmem-vm #119 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Workqueue: events async_pf_execute [kvm] RIP: 0010:kvm_put_kvm+0x2d/0x320 [kvm] Call Trace: async_pf_execute+0x198/0x260 [kvm] process_one_work+0x145/0x2d0 worker_thread+0x27e/0x3a0 kthread+0xba/0xe0 ret_from_fork+0x2d/0x50 ret_from_fork_asm+0x11/0x20 ---[ end trace 0000000000000000 ]--- INFO: task kworker/8:1:251 blocked for more than 120 seconds.

And that in turn fixes the moduleunloading bug as __fput() won't do module_put() on the last vCPU referenceuntil the vCPU has been freed, e.g. if closing the vCPU file also puts thelast reference to the KVM module.Note that kvm_check_async_pf_completion() may also take the work item offthe completion queue and so also needs to flush the work queue, as thework will not be seen by kvm_clear_async_pf_completion_queue(). Waitingon the workqueue could theoretically delay a vCPU due to waiting for thework to complete, but that's a very, very small chance, and likely a verysmall delay. kvm_arch_async_page_present_queued() unconditionally makes anew request, i.e. will effectively delay entering the guest, so theremaining work is really just: trace_kvm_async_pf_completed(addr, cr2_or_gpa); __kvm_vcpu_wake_up(vcpu); mmput(mm);and mmput() can't drop the last reference to the page tables if the vCPU isstill alive, i.e. the vCPU won't get stuck tearing down page tables.Add a helper to do the flushing, specifically to deal with "wakeup all"work items, as they aren't actually work items, i.e. are never placed in aworkqueue. Trying to flush a bogus workqueue entry rightly makes__flush_work() complain (kudos to whoever added that sanity check).Note, commit 5f6de5cbebee ("KVM: Prevent module exit until al---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: check the inode number is not the invalid value of zeroSyskiller has produced an out of bounds access in fill_meta_index().That out of bounds access is ultimately caused because the inodehas an inode number with the invalid value of zero, which was not checked.The reason this causes the out of bounds access is due to followingsequence of events:1. Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).2. When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.This patch adds a sanity check which checks that the inode numberis not zero when the inode is created and returns -EINVAL if it is.[phillip@squashfs.org.uk: whitespace fix]

Description: In the Linux kernel, the following vulnerability has been resolved:dm-raid: really frozen sync_thread during suspend1) commit f52f5c71f3d4 ("md: fix stopping sync thread") remove MD_RECOVERY_FROZEN from __md_stop_writes() and doesn't realize that dm-raid relies on __md_stop_writes() to frozen sync_thread indirectly. Fix this problem by adding MD_RECOVERY_FROZEN in md_stop_writes(), and since stop_sync_thread() is only used for dm-raid in this case, also move stop_sync_thread() to md_stop_writes().2) The flag MD_RECOVERY_FROZEN doesn't mean that sync thread is frozen, it only prevent new sync_thread to start, and it can't stop the running sync thread; In order to frozen sync_thread, after seting the flag, stop_sync_thread() should be used.3) The flag MD_RECOVERY_FROZEN doesn't mean that writes are stopped, use it as condition for md_stop_writes() in raid_postsuspend() doesn't look correct. Consider that reentrant stop_sync_thread() do nothing, always call md_stop_writes() in raid_postsuspend().4) raid_message can set/clear the flag MD_RECOVERY_FROZEN at anytime, and if MD_RECOVERY_FROZEN is cleared while the array is suspended, new sync_thread can start unexpected. Fix this by disallow raid_message() to change sync_thread status during suspend.Note that after commit f52f5c71f3d4 ("md: fix stopping sync thread"), thetest shell/lvconvert-raid-reshape.sh start to hang in stop_sync_thread(),and with previous fixes, the test won't hang there anymore, however, thetest will still fail and complain that ext4 is corrupted. And with thispatch, the test won't hang due to stop_sync_thread() or fail due to ext4is corrupted anymore. However, there is still a deadlock related todm-raid456 that will be fixed in following patches.

To peek into theoriginal net_device we will use dev_get_by_index_rcu(). Thus either weget device and are safe to use it or we don't get it and drop skb.

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Prevent double free on errorThe error handling path in its_vpe_irq_domain_alloc() causes a double freewhen its_vpe_init() fails after successfully allocating at least oneinterrupt. This happens because its_vpe_irq_domain_free() frees theinterrupts along with the area bitmap and the vprop_page andits_vpe_irq_domain_alloc() subsequently frees the area bitmap and thevprop_page again.Fix this by unconditionally invoking its_vpe_irq_domain_free() whichhandles all cases correctly and by removing the bitmap/vprop_page freeingfrom its_vpe_irq_domain_alloc().[ tglx: Massaged change log ]

Description: In the Linux kernel, the following vulnerability has been resolved:tcp: properly terminate timers for kernel socketsWe had various syzbot reports about tcp timers firing afterthe corresponding netns has been dismantled.Fortunately Josef Bacik could trigger the issue more often,and could test a patch I wrote two years ago.When TCP sockets are closed, we call inet_csk_clear_xmit_timers()to 'stop' the timers.inet_csk_clear_xmit_timers() can be called from any context,including when socket lock is held.This is the reason it uses sk_stop_timer(), aka del_timer().This means that ongoing timers might finish much later.For user sockets, this is fine because each running timerholds a reference on the socket, and the user socket holdsa reference on the netns.For kernel sockets, we risk that the netns is freed beforetimer can complete, because kernel sockets do not holdreference on the netns.This patch adds inet_csk_clear_xmit_timers_sync() functionthat using sk_stop_timer_sync() to make sure all timersare terminated before the kernel socket is released.Modules using kernel sockets close them in their netns exit()handler.Also add sock_not_owned_by_me() helper to get LOCKDEPsupport : inet_csk_clear_xmit_timers_sync() must not be calledwhile socket lock is held.It is very possible we can revert in the future commit3a58f13a881e ("net: rds: acquire refcount on TCP sockets")which attempted to solve the issue in rds only.(net/smc/af_smc.c and net/mptcp/subflow.c have similar code)We probably can remove the check_net() tests fromtcp_out_of_resources() and __tcp_close() in the future.

Description: In the Linux kernel, the following vulnerability has been resolved:Drivers: hv: vmbus: Don't free ring buffers that couldn't be re-encryptedIn CoCo VMs it is possible for the untrusted host to causeset_memory_encrypted() or set_memory_decrypted() to fail such that anerror is returned and the resulting memory is shared. Callers need totake care to handle these errors to avoid returning decrypted (shared)memory to the page allocator, which could lead to functional or securityissues.The VMBus ring buffer code could free decrypted/shared pages ifset_memory_decrypted() fails. Check the decrypted field in the structvmbus_gpadl for the ring buffers to decide whether to free the memory.

Description: In the Linux kernel, the following vulnerability has been resolved:Reapply "drm/qxl: simplify qxl_fence_wait"This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds"and further debugging points to a possible circular locking dependencybetween the console_owner locking and the worker pool locking.Reverting the commit allows Steve's VM to boot to completion again.[ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ]

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: ecdh - explicitly zeroize private_keyprivate_key is overwritten with the key parameter passed in by thecaller (if present), or alternatively a newly generated private key.However, it is possible that the caller provides a key (or the newlygenerated key) which is shorter than the previous key. In thatscenario, some key material from the previous key would not beoverwritten. The easiest solution is to explicitly zeroize the entireprivate_key array first.Note that this patch slightly changes the behavior of this function:previously, if the ecc_gen_privkey failed, the old private_key wouldremain. Now, the private_key is always zeroized. This behavior isconsistent with the case where params.key is set and ecc_is_key_validfails.

That's why count is equal to 1.Therefore add the ext4_check_dx_root() helper function to add more sanitychecks to dot and dotdot before starting the conversion to avoid the aboveissue.

Description: In the Linux kernel, the following vulnerability has been resolved:udf: Avoid using corrupted block bitmap bufferWhen the filesystem block bitmap is corrupted, we detect the corruptionwhile loading the bitmap and fail the allocation with error. However thenext allocation from the same bitmap will notice the bitmap buffer isalready loaded and tries to allocate from the bitmap with mixed results(depending on the exact nature of the bitmap corruption). Fix theproblem by using BH_verified bit to indicate whether the bitmap is validor not.

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: prevent potential speculation leaks in gpio_device_get_desc()Userspace may trigger a speculative read of an address outside the gpiodescriptor array.Users can do that by calling gpio_ioctl() with an offset out of range.Offset is copied from user and then used as an array index to getthe gpio descriptor without sanitization in gpio_device_get_desc().This change ensures that the offset is sanitized by usingarray_index_nospec() to mitigate any possibility of speculativeinformation leaks.This bug was discovered and resolved using Coverity Static AnalysisSecurity Testing (SAST) by Synopsys, Inc.

Description: In the Linux kernel, the following vulnerability has been resolved:fuse: Initialize beyond-EOF page contents before setting uptodatefuse_notify_store(), unlike fuse_do_readpage(), does not enable pagezeroing (because it can be used to change partial page contents).So fuse_notify_store() must be more careful to fully initialize pagecontents (including parts of the page that are beyond end-of-file)before marking the page uptodate.The current code can leave beyond-EOF page contents uninitialized, whichmakes these uninitialized page contents visible to userspace via mmap().This is an information leak, but only affects systems which do notenable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or thecorresponding kernel command line parameter).

Description: In the Linux kernel, the following vulnerability has been resolved:x86/mtrr: Check if fixed MTRRs exist before saving themMTRRs have an obsolete fixed variant for fine grained caching controlof the 640K-1MB region that uses separate MSRs. This fixed variant hasa separate capability bit in the MTRR capability MSR.So far all x86 CPUs which support MTRR have this separate bit set, so itwent unnoticed that mtrr_save_state() does not check the capability bitbefore accessing the fixed MTRR MSRs.Though on a CPU that does not support the fixed MTRR capability thisresults in a #GP. The #GP itself is harmless because the RDMSR fault ishandled gracefully, but results in a WARN_ON().Add the missing capability check to prevent this.

Description: In the Linux kernel, the following vulnerability has been resolved:selinux,smack: don't bypass permissions check in inode_setsecctx hookMarek Gresko reports that the root user on an NFS client is able tochange the security labels on files on an NFS filesystem that isexported with root squashing enabled.The end of the kerneldoc comment for __vfs_setxattr_noperm() states: * This function requires the caller to lock the inode's i_mutex before it * is executed. It also assumes that the caller will make the appropriate * permission checks.nfsd_setattr() does do permissions checking via fh_verify() andnfsd_permission(), but those don't do all the same permissions checksthat are done by security_inode_setxattr() and its related LSM hooks do.Since nfsd_setattr() is the only consumer of security_inode_setsecctx(),simplest solution appears to be to replace the call to__vfs_setxattr_noperm() with a call to __vfs_setxattr_locked(). Thisfixes the above issue and has the added benefit of causing nfsd torecall conflicting delegations on a file when a client tries to changeits security label.

Description: In the Linux kernel, the following vulnerability has been resolved:Squashfs: sanity check symbolic link sizeSyzkiller reports a "KMSAN: uninit-value in pick_link" bug.This is caused by an uninitialised page, which is ultimately causedby a corrupted symbolic link size read from disk.The reason why the corrupted symlink size causes an uninitialisedpage is due to the following sequence of events:1. squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.2. Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.3. The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.This patch adds a sanity check which checks that the symboliclink size is not larger than expected.--V2: fix spelling mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:Input: uinput - reject requests with unreasonable number of slotsWhen exercising uinput interface syzkaller may try setting up devicewith a really large number of slots, which causes memory allocationfailure in input_mt_init_slots(). While this allocation failure ishandled properly and request is rejected, it results in syzkallerreports. Additionally, such request may put undue burden on thesystem which will try to free a lot of memory for a bogus request.Fix it by limiting allowed number of slots to 100. This can easilybe extended if we see devices that can track more than 100 contacts.

Description: In the Linux kernel, the following vulnerability has been resolved:pci/hotplug/pnv_php: Fix hotplug driver crash on PowernvThe hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernelcrash when we try to hot-unplug/disable the PCIe switch/bridge fromthe PHB.The crash occurs because although the MSI data structure has beenreleased during disable/hot-unplug path and it has been assignedwith NULL, still during unregistration the code was again trying toexplicitly disable the MSI which causes the NULL pointer dereference andkernel crash.The patch fixes the check during unregistration path to prevent invokingpci_disable_msi/msix() since its data structure is already freed.

[0]The NULL pointer is sk->sk_user_data, and the offset 8 is of protocolin struct fou.When fou_release() is called due to netns dismantle or explicit tunnelteardown, udp_tunnel_sock_release() sets NULL to sk->sk_user_data.Then, the tunnel socket is destroyed after a single RCU grace period.So, in-flight udp4_gro_receive() could find the socket and execute theFOU GRO handler, where sk->sk_user_data could be NULL.Let's use rcu_dereference_sk_user_data() in fou_from_sock() and add NULLchecks in FOU GRO handlers.[0]:BUG: kernel NULL pointer dereference, address: 0000000000000008 PF: supervisor read access in kernel mode PF: error_code(0x0000) - not-present pagePGD 80000001032f4067 P4D 80000001032f4067 PUD 103240067 PMD 0SMP PTICPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.216-204.855.amzn2.x86_64 #1Hardware name: Amazon EC2 c5.large/, BIOS 1.0 10/16/2017RIP: 0010:fou_gro_receive (net/ipv4/fou.c:233) [fou]Code: 41 5f c3 cc cc cc cc e8 e7 2e 69 f4 0f 1f 80 00 00 00 00 0f 1f 44 00 00 49 89 f8 41 54 48 89 f7 48 89 d6 49 8b 80 88 02 00 00 <0f> b6 48 08 0f b7 42 4a 66 25 fd fd 80 cc 02 66 89 42 4a 0f b6 42RSP: 0018:ffffa330c0003d08 EFLAGS: 00010297RAX: 0000000000000000 RBX: ffff93d9e3a6b900 RCX: 0000000000000010RDX: ffff93d9e3a6b900 RSI: ffff93d9e3a6b900 RDI: ffff93dac2e24d08RBP: ffff93d9e3a6b900 R08: ffff93dacbce6400 R09: 0000000000000002R10: 0000000000000000 R11: ffffffffb5f369b0 R12: ffff93dacbce6400R13: ffff93dac2e24d08 R14: 0000000000000000 R15: ffffffffb4edd1c0FS: 0000000000000000(0000) GS:ffff93daee800000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000000000008 CR3: 0000000102140001 CR4: 00000000007706f0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400PKRU: 55555554Call Trace: ? show_trace_log_lvl (arch/x86/kernel/dumpstack.c:259) ? __die_body.cold (arch/x86/kernel/dumpstack.c:478 arch/x86/kernel/dumpstack.c:420) ? no_context (arch/x86/mm/fault.c:752) ? exc_page_fault (arch/x86/include/asm/irqflags.h:49 arch/x86/include/asm/irqflags.h:89 arch/x86/mm/fault.c:1435 arch/x86/mm/fault.c:1483) ? asm_exc_page_fault (arch/x86/include/asm/idtentry.h:571) ? fou_gro_receive (net/ipv4/fou.c:233) [fou] udp_gro_receive (include/linux/netdevice.h:2552 net/ipv4/udp_offload.c:559) udp4_gro_receive (net/ipv4/udp_offload.c:604) inet_gro_receive (net/ipv4/af_inet.c:1549 (discriminator 7)) dev_gro_receive (net/core/dev.c:6035 (discriminator 4)) napi_gro_receive (net/core/dev.c:6170) ena_clean_rx_irq (drivers/amazon/net/ena/ena_netdev.c:1558) [ena] ena_io_poll (drivers/amazon/net/ena/ena_netdev.c:1742) [ena] napi_poll (net/core/dev.c:6847) net_rx_action (net/core/dev.c:6917) __do_softirq (arch/x86/include/asm/jump_label.h:25 include/linux/jump_label.h:200 include/trace/events/irq.h:142 kernel/softirq.c:299) asm_call_irq_on_stack (arch/x86/entry/entry_64.S:809) do_softirq_own_stack (arch/x86/include/asm/irq_stack.h:27 arch/x86/include/asm/irq_stack.h:77 arch/x86/kernel/irq_64.c:77) irq_exit_rcu (kernel/softirq.c:393 kernel/softirq.c:423 kernel/softirq.c:435) common_interrupt (arch/x86/kernel/irq.c:239) asm_common_interrupt (arch/x86/include/asm/idtentry.h:626)RIP: 0010:acpi_idle_do_entry (arch/x86/include/asm/irqflags.h:49 arch/x86/include/asm/irqflags.h:89 drivers/acpi/processor_idle.c:114 drivers/acpi/processor_idle.c:575)Code: 8b 15 d1 3c c4 02 ed c3 cc cc cc cc 65 48 8b 04 25 40 ef 01 00 48 8b 00 a8 08 75 eb 0f 1f 44 00 00 0f 00 2d d5 09 55 00 fb f4 c3 cc cc cc cc e9 be fc ff ff 66 66 2e 0f 1f 84 00 00 00 00 00RSP: 0018:ffffffffb5603e58 EFLAGS: 00000246RAX: 0000000000004000 RBX: ffff93dac0929c00 RCX: ffff93daee833900RDX: ffff93daee800000 RSI: ffff93d---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:userfaultfd: fix checks for huge PMDsPatch series "userfaultfd: fix races around pmd_trans_huge() check", v2.The pmd_trans_huge() code in mfill_atomic() is wrong in three differentways depending on kernel version:1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().3. On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.I decided to write two separate fixes for these (one fix for bugs 1+2, onefix for bug 3), so that the first fix can be backported to kernelsaffected by bugs 1+2.This patch (of 2):This fixes two issues.I discovered that the following race can occur: mfill_atomic other thread ============ ============
pmdp_get_lockless() [reads none pmd] __pte_alloc [no-op] BUG_ON(pmd_none(*dst_pmd))I have experimentally verified this in a kernel with extra mdelay() calls;the BUG_ON(pmd_none(*dst_pmd)) triggers.On kernels newer than commit 0d940a9b270b ("mm/pgtable: allowpte_offset_map[_lock]() to fail"), this can't lead to anything worse thana BUG_ON(), since the page table access helpers are actually designed todeal with page tables concurrently disappearing; but on older kernels(<=6.4), I think we could probably theoretically race past the twoBUG_ON() checks and end up treating a hugepage as a page table.The second issue is that, as Qi Zheng pointed out, there are other typesof huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs(in particular, migration PMDs).On <=6.4, this is worse than the first issue: If mfill_atomic() runs on aPMD that contains a migration entry (which just requires winning a single,fairly wide race), it will pass the PMD to pte_offset_map_lock(), whichassumes that the PMD points to a page table.Breakage follows: First, the kernel tries to take the PTE lock (which willcrash or maybe worse if there is no "struct page" for the address bits inthe migration entry PMD - I think at least on X86 there usually is nocorresponding "struct page" thanks to the PTE inversion mitigation, amd64looks different).If that didn't crash, the kernel would next try to write a PTE into whatit wrongly thinks is a page table.As part of fixing these issues, get rid of the check for pmd_trans_huge()before __pte_alloc() - that's redundant, we're going to have to check forthat after the __pte_alloc() anyway.Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64: acpi: Harden get_cpu_for_acpi_id() against missing CPU entryIn a review discussion of the changes to support vCPU hotplug wherea check was added on the GICC being enabled if was online, it wasnoted that there is need to map back to the cpu and use that to indexinto a cpumask. As such, a valid ID is needed.If an MPIDR check fails in acpi_map_gic_cpu_interface() it is possiblefor the entry in cpu_madt_gicc[cpu] == NULL. This function wouldthen cause a NULL pointer dereference. Whilst a path to triggerthis has not been established, harden this caller against thepossibility.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: clean up our handling of refs == 0 in snapshot deleteIn reada we BUG_ON(refs == 0), which could be unkind since we aren'tholding a lock on the extent leaf and thus could get a transientincorrect answer. In walk_down_proc we also BUG_ON(refs == 0), whichcould happen if we have extent tree corruption. Change that to return-EUCLEAN. In do_walk_down() we catch this case and handle it correctly,however we return -EIO, which -EUCLEAN is a more appropriate error code.Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convertthat to proper error handling. Also adjust the error message so we canactually do something with the information.

(For thedetails, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/)The HSW11 requires a period larger than 100 for the INST_RETIRED.ALLevent, but the initial period in the freq mode is 1. The erratum is thesame as the BDM11, which has been supported in the kernel. A minimumperiod of 128 is enforced as well on HSW.HSW143 is regarding that the fixed counter 1 may overcount 32 with theHyper-Threading is enabled. However, based on the test, the hardwarehas more issues than it tells. Besides the fixed counter 1, the message'interrupt took too long' can be observed on any counter which was armedwith a period < 32 and two events expired in the same NMI. A minimumperiod of 32 is enforced for the rest of the events.The recommended workaround code of the HSW143 is not implemented.Because it only addresses the issue for the fixed counter. It bringsextra overhead through extra MSR writing. No related overcounting issuehas been reported so far.

Description: In the Linux kernel, the following vulnerability has been resolved:platform/x86: panasonic-laptop: Fix SINF array out of bounds accessesThe panasonic laptop code in various places uses the SINF array with indexvalues of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF arrayis big enough.Not all panasonic laptops have this many SINF array entries, for examplethe Toughbook CF-18 model only has 10 SINF array entries. So it onlysupports the AC+DC brightness entries and mute.Check that the SINF array has a minimum size which covers all AC+DCbrightness entries and refuse to load if the SINF array is smaller.For higher SINF indexes hide the sysfs attributes when the SINF arraydoes not contain an entry for that attribute, avoiding show()/store()accessing the array out of bounds and add bounds checking to the probe()and resume() code accessing these.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: pm80xx: Set phy->enable_completion only when we wait for itpm8001_phy_control() populates the enable_completion pointer with a stackaddress, sends a PHY_LINK_RESET / PHY_HARD_RESET, waits 300 ms, andreturns. The problem arises when a phy control response comes late. After300 ms the pm8001_phy_control() function returns and the passedenable_completion stack address is no longer valid. Late phy controlresponse invokes complete() on a dangling enable_completion pointer whichleads to a kernel crash.

Description: In the Linux kernel, the following vulnerability has been resolved:icmp: change the order of rate limitsICMP messages are ratelimited :After the blamed commits, the two rate limiters are applied in this order:1) host wide ratelimit (icmp_global_allow())2) Per destination ratelimit (inetpeer based)In order to avoid side-channels attacks, we need to applythe per destination check first.This patch makes the following change :1) icmp_global_allow() checks if the host wide limit is reached. But credits are not yet consumed. This is deferred to 3)2) The per destination limit is checked/updated. This might add a new node in inetpeer tree.3) icmp_global_consume() consumes tokens if prior operations succeeded.This means that host wide ratelimit is still effectivein keeping inetpeer tree small even under DDOS.As a bonus, I removed icmp_global.lock as the fast pathcan use a lock-free operation.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmitSyzbot points out that skb_trim() has a sanity check on the existing length ofthe skb, which can be uninitialised in some error paths. The intent here isclearly just to reset the length to zero before resubmitting, so switch tocalling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()already contains a call to skb_reset_tail_pointer(), so remove the redundantcall.The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similarusage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

Description: In the Linux kernel, the following vulnerability has been resolved:ocfs2: reserve space for inline xattr before attaching reflink treeOne of our customers reported a crash and a corrupted ocfs2 filesystem. The crash was due to the detection of corruption. Upon troubleshooting,the fsck -fn output showed the below corruption[EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record,but fsck believes the largest valid value is 227. Clamp the next record value? nThe stat output from the debugfs.ocfs2 showed the following corruptionwhere the "Next Free Rec:" had overshot the "Count:" in the root metadatablock.

The problematic function is ocfs2_reflink_xattr_inline(). By thetime this function is called the reflink tree is already recreated at thedestination inode from the source inode. At this point, this functionreserves space for inline xattrs at the destination inode without evenchecking if there is space at the root metadata block. It simply reducesthe l_count from 243 to 227 thereby making space of 256 bytes for inlinexattr whereas the inode already has extents beyond this index (in thiscase up to 230), thereby causing corruption.The fix for this is to reserve space for inline metadata at the destinationinode before the reflink tree gets recreated. The customer has verified thefix.

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: Fix buffer overflow when parsing NFS reparse pointsReparseDataLength is sum of the InodeType size and DataBuffer size.So to get DataBuffer size it is needed to subtract InodeType's size fromReparseDataLength.Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBufferat position after the end of the buffer because it does not subtractInodeType size from the length. Fix this problem and correctly subtractvariable len.Member InodeType is present only when reparse buffer is large enough. Checkfor ReparseDataLength before accessing InodeType to prevent another invalidmemory access.Major and minor rdev values are present also only when reparse buffer islarge enough. Check for reparse buffer size before calling reparse_mkdev().

Description: In the Linux kernel, the following vulnerability has been resolved:net: do not delay dst_entries_add() in dst_release()dst_entries_add() uses per-cpu data that might be freed at netnsdismantle from ip6_route_net_exit() calling dst_entries_destroy()Before ip6_route_net_exit() can be called, we release allthe dsts associated with this netns, via calls to dst_release(),which waits an rcu grace period before calling dst_destroy()dst_entries_add() use in dst_destroy() is racy, becausedst_entries_destroy() could have been called already.Decrementing the number of dsts must happen sooner.Notes:1) in CONFIG_XFRM case, dst_destroy() can call dst_release_immediate(child), this might also cause UAF if the child does not have DST_NOCOUNT set. IPSEC maintainers might take a look and see how to address this.2) There is also discussion about removing this count of dst, which might happen in future kernels.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: br_netfilter: fix panic with metadata_dst skbFix a kernel panic in the br_netfilter module when sending untaggedtraffic via a VxLAN device.This happens during the check for fragmentation in br_nf_dev_queue_xmit.It is dependent on:1) the br_netfilter module being loaded;2) net.bridge.bridge-nf-call-iptables set to 1;3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;4) untagged frames with size higher than the VxLAN MTU forwarded/floodedWhen forwarding the untagged packet to the VxLAN bridge port, beforethe netfilter hooks are called, br_handle_egress_vlan_tunnel is called andchanges the skb_dst to the tunnel dst. The tunnel_dst is a metadata typeof dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL.Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a checkfor frames that needs to be fragmented: frames with higher MTU than theVxLAN device end up calling br_nf_ip_fragment, which in turns callip_skb_dst_mtu.The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dstwith valid dst->dev, thus the crash.This case was never supported in the first place, so drop the packetinstead.PING 10.0.0.2 (10.0.0.2) from 0.0.0.0 h1-eth0: 2000(2028) bytes of data.[ 176.291791] Unable to handle kernel NULL pointer dereference atvirtual address 0000000000000110[ 176.292101] Mem abort info:[ 176.292184] ESR = 0x0000000096000004[ 176.292322] EC = 0x25: DABT (current EL), IL = 32 bits[ 176.292530] SET = 0, FnV = 0[ 176.292709] EA = 0, S1PTW = 0[ 176.292862] FSC = 0x04: level 0 translation fault[ 176.293013] Data abort info:[ 176.293104] ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000[ 176.293488] CM = 0, WnR = 0, TnD = 0, TagAccess = 0[ 176.293787] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 176.293995] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000043ef5000[ 176.294166] [0000000000000110] pgd=0000000000000000,p4d=0000000000000000[ 176.294827] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP[ 176.295252] Modules linked in: vxlan ip6_udp_tunnel udp_tunnel vethbr_netfilter bridge stp llc ipv6 crct10dif_ce[ 176.295923] CPU: 0 PID: 188 Comm: ping Not tainted6.8.0-rc3-g5b3fbd61b9d1 #2[ 176.296314] Hardware name: linux,dummy-virt (DT)[ 176.296535] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBSBTYPE=--)[ 176.296808] pc : br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter][ 176.297382] lr : br_nf_dev_queue_xmit+0x2ac/0x4ec [br_netfilter][ 176.297636] sp : ffff800080003630[ 176.297743] x29: ffff800080003630 x28: 0000000000000008 x27:ffff6828c49ad9f8[ 176.298093] x26: ffff6828c49ad000 x25: 0000000000000000 x24:00000000000003e8[ 176.298430] x23: 0000000000000000 x22: ffff6828c4960b40 x21:ffff6828c3b16d28[ 176.298652] x20: ffff6828c3167048 x19: ffff6828c3b16d00 x18:0000000000000014[ 176.298926] x17: ffffb0476322f000 x16: ffffb7e164023730 x15:0000000095744632[ 176.299296] x14: ffff6828c3f1c880 x13: 0000000000000002 x12:ffffb7e137926a70[ 176.299574] x11: 0000000000000001 x10: ffff6828c3f1c898 x9 :0000000000000000[ 176.300049] x8 : ffff6828c49bf070 x7 : 0008460f18d5f20e x6 :f20e0100bebafeca[ 176.300302] x5 : ffff6828c7f918fe x4 : ffff6828c49bf070 x3 :0000000000000000[ 176.300586] x2 : 0000000000000000 x1 : ffff6828c3c7ad00 x0 :ffff6828c7f918f0[ 176.300889] Call trace:[ 176.301123] br_nf_dev_queue_xmit+0x390/0x4ec [br_netfilter][ 176.301411] br_nf_post_routing+0x2a8/0x3e4 [br_netfilter][ 176.301703] nf_hook_slow+0x48/0x124[ 176.302060] br_forward_finish+0xc8/0xe8 [bridge][ 176.302371] br_nf_hook_thresh+0x124/0x134 [br_netfilter][ 176.302605] br_nf_forward_finish+0x118/0x22c [br_netfilter][ 176.302824] br_nf_forward_ip.part.0+0x264/0x290 [br_netfilter][ 176.303136] br_nf_forward+0x2b8/0x4e0 [br_netfilter][ 176.303359] nf_hook_slow+0x48/0x124[ 176.303---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:serial: protect uart_port_dtr_rts() in uart_shutdown() tooCommit af224ca2df29 (serial: core: Prevent unsafe uart port access, part3) added few uport == NULL checks. It added one to uart_shutdown(), sothe commit assumes, uport can be NULL in there. But right after thatprotection, there is an unprotected "uart_port_dtr_rts(uport, false);"call. That is invoked only if HUPCL is set, so I assume that is thereason why we do not see lots of these reports.Or it cannot be NULL at this point at all for some reason :P.Until the above is investigated, stay on the safe side and move thisdereference to the if too.I got this inconsistency from Coverity under CID 1585130.

Description: In the Linux kernel, the following vulnerability has been resolved:parport: Proper fix for array out-of-bounds accessThe recent fix for array out-of-bounds accesses replaced sprintf()calls blindly with snprintf(). However, since snprintf() returns thewould-be-printed size, not the actually output size, the lengthcalculation can still go over the given limit.Use scnprintf() instead of snprintf(), which returns the actuallyoutput letters, for addressing the potential out-of-bounds accessproperly.

Description: In the Linux kernel, the following vulnerability has been resolved:nfsd: fix race between laundromat and free_stateidThere is a race between laundromat handling of revoked delegationsand a client sending free_stateid operation. Laundromat threadfinds that delegation has expired and needs to be revoked so itmarks the delegation stid revoked and it puts it on a reaper listbut then it unlock the state lock and the actual delegation revocationhappens without the lock. Once the stid is marked revoked a racingfree_stateid processing thread does the following (1) it callslist_del_init() which removes it from the reaper list and (2) freesthe delegation stid structure. The laundromat thread ends up notcalling the revoke_delegation() function for this particular delegationbut that means it will no release the lock lease that exists onthe file.Now, a new open for this file comes in and ends up finding thatlease list isn't empty and calls nfsd_breaker_owns_lease() which endsup trying to derefence a freed delegation stateid.

Then, coordinating whether the stid has been puton the cl_revoked list or we are processing FREE_STATEID and need tomake sure to remove it from the list, each check that state and actaccordingly. If laundromat has added to the cl_revoke list beforethe arrival of FREE_STATEID, then nfsd4_free_stateid() knows to removeit from the list. If nfsd4_free_stateid() finds that operations arrivedbefore laundromat has placed it on cl_revoke list, it marks the statefreed and then laundromat will no longer add it to the list.Also, for nfsd4_delegreturn() when looking for the specified stid,we need to access stid that are marked removed or freeable, it meansthe laundromat has started processing it but hasn't finished and thisdelegreturn needs to return nfserr_deleg_revoked and notnfserr_bad_stateid. The latter will not trigger a FREE_STATEID and thelack of it will leave this stid on the cl_revoked list indefinitely.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/vc4: Stop the active perfmon before being destroyedUpon closing the file descriptor, the active performance monitor is notstopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`,the active performance monitor's pointer (`vc4->active_perfmon`) is stillretained.If we open a new file descriptor and submit a few jobs with performancemonitors, the driver will attempt to stop the active performance monitorusing the stale pointer in `vc4->active_perfmon`. However, this pointeris no longer valid because the previous process has already terminated,and all performance monitors associated with it have been destroyed andfreed.To fix this, when the active performance monitor belongs to a givenprocess, explicitly stop it before destroying and freeing it.

Description: In the Linux kernel, the following vulnerability has been resolved:posix-clock: Fix missing timespec64 check in pc_clock_settime()As Andrew pointed out, it will make sense that the PTP corechecked timespec64 struct's tv_sec and tv_nsec range before callingptp->info->settime64().As the man manual of clock_settime() said, if tp.tv_sec is negative ortp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,which include dynamic clocks which handles PTP clock, and the condition isconsistent with timespec64_valid(). As Thomas suggested, timespec64_valid()only check the timespec is valid, but not ensure that the time isin a valid range, so check it ahead using timespec64_valid_strict()in pc_clock_settime() and return -EINVAL if not valid.There are some drivers that use tp->tv_sec and tp->tv_nsec directly towrite registers without validity checks and assume that the higher layerhas checked it, which is dangerous and will benefit from this, such ashclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),and some drivers can remove the checks of itself.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: reject VHT opmode for unsupported channel widthsVHT operating mode notifications are not defined for channel widthsbelow 20 MHz. In particular, 5 MHz and 10 MHz are not valid under theVHT specification and must be rejected.Without this check, malformed notifications using these widths mayreach ieee80211_chan_width_to_rx_bw(), leading to a WARN_ON due toinvalid input. This issue was reported by syzbot.Reject these unsupported widths early in sta_link_apply_parameters()when opmode_notif is used. The accepted set includes 20, 40, 80, 160,and 80+80 MHz, which are valid for VHT. While 320 MHz is not definedfor VHT, it is allowed to avoid rejecting HE or EHT clients that maystill send a VHT opmode notification.

Description: In the Linux kernel, the following vulnerability has been resolved:eventpoll: Fix semi-unbounded recursionEnsure that epoll instances can never form a graph deeper thanEP_MAX_NESTS+1 links.Currently, ep_loop_check_proc() ensures that the graph is loop-free anddoes some recursion depth checks, but those recursion depth checks don'tlimit the depth of the resulting tree for two reasons: - They don't look upwards in the tree. - If there are multiple downwards paths of different lengths, only one of the paths is actually considered for the depth check since commit 28d82dc1c4ed ("epoll: limit paths").Essentially, the current recursion depth check in ep_loop_check_proc() justserves to prevent it from recursing too deeply while checking for loops.A more thorough check is done in reverse_path_check() after the new graphedge has already been created; this checks, among other things, that nopaths going upwards from any non-epoll file with a length of more than 5edges exist. However, this check does not apply to non-epoll files.As a result, it is possible to recurse to a depth of at least roughly 500,tested on v6.15. (I am unsure if deeper recursion is possible; and this mayhave changed with commit 8c44dac8add7 ("eventpoll: Fix priority inversionproblem").)To fix it:1. In ep_loop_check_proc(), note the subtree depth of each visited node,and use subtree depths for the total depth calculation even when a subtreehas already been visited.2. Add ep_get_upwards_depth_proc() for similarly determining the maximumdepth of an upwards walk.3. In ep_loop_check(), use these values to limit the total path lengthbetween epoll nodes to EP_MAX_NESTS edges.

Description: In the Linux kernel, the following vulnerability has been resolved:xfrm: state: initialize state_ptrs earlier in xfrm_state_findIn case of preemption, xfrm_state_look_at will find a differentpcpu_id and look up states for that other CPU. If we matched a statefor CPU2 in the state_cache while the lookup started on CPU1, we willjump to "found", but the "best" state that we got will be ignored andwe will enter the "acquire" block. This block uses state_ptrs, whichisn't initialized at this point.Let's initialize state_ptrs just after taking rcu_read_lock. This willalso prevent a possible misuse in the future, if someone adjusts thisfunction.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: fix race between polling and detachingsyzbot reports a use-after-free in comedi in the below link, which isdue to comedi gladly removing the allocated async area even though pollrequests are still active on the wait_queue_head inside of it. This cancause a use-after-free when the poll entries are later triggered orremoved, as the memory for the wait_queue_head has been freed. We needto check there are no tasks queued on any of the subdevices' wait queuesbefore allowing the device to be detached by the `COMEDI_DEVCONFIG`ioctl.Tasks will read-lock `dev->attach_lock` before adding themselves to thesubdevice wait queue, so fix the problem in the `COMEDI_DEVCONFIG` ioctlhandler by write-locking `dev->attach_lock` before checking that all ofthe subdevices are safe to be deleted. This includes testing for anysleepers on the subdevices' wait queues. It remains locked until thedevice has been detached. This requires the `comedi_device_detach()`function to be refactored slightly, moving the bulk of it into newfunction `comedi_device_detach_locked()`.Note that the refactor of `comedi_device_detach()` results in`comedi_device_cancel_all()` now being called while `dev->attach_lock`is write-locked, which wasn't the case previously, but that does notmatter.Thanks to Jens Axboe for diagnosing the problem and co-developing thispatch.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: fix refcount leak on table dumpThere is a reference count leak in ctnetlink_dump_table(): if (res < 0) { nf_conntrack_get(&ct->ct_general); // HERE cb->args[1] = (unsigned long)ct; ...While its very unlikely, its possible that ct == last.If this happens, then the refcount of ct was already incremented.This 2nd increment is never undone.This prevents the conntrack object from being released, which in turnkeeps prevents cnet->count from dropping back to 0.This will then block the netns dismantle (or conntrack rmmod) asnf_conntrack_cleanup_net_list() will wait forever.This can be reproduced by running conntrack_resize.sh selftest in a loop.It takes ~20 minutes for me on a preemptible kernel on average beforeI see a runaway kworker spinning in nf_conntrack_cleanup_net_list.One fix would to change this to: if (res < 0) { if (ct != last) nf_conntrack_get(&ct->ct_general);But this reference counting isn't needed in the first place.We can just store a cookie value instead.A followup patch will do the same for ctnetlink_exp_dump_table,it looks to me as if this has the same problem and likectnetlink_dump_table, we only need a 'skip hint', not the actualobject so we can apply the same cookie strategy there as well.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fix use of uninitialized memory in do_insn_ioctl() and do_insnlist_ioctl()syzbot reports a KMSAN kernel-infoleak in `do_insn_ioctl()`. A kernelbuffer is allocated to hold `insn->n` samples (each of which is an`unsigned int`). For some instruction types, `insn->n` samples arecopied back to user-space, unless an error code is being returned. Theproblem is that not all the instruction handlers that need to returndata to userspace fill in the whole `insn->n` samples, so that there isan information leak. There is a similar syzbot report for`do_insnlist_ioctl()`, although it does not have a reproducer for it atthe time of writing.One culprit is `insn_rw_emulate_bits()` which is used as the handler for`INSN_READ` or `INSN_WRITE` instructions for subdevices that do not havea specific handler for that instruction, but do have an `INSN_BITS`handler. For `INSN_READ` it only fills in at most 1 sample, so if`insn->n` is greater than 1, the remaining `insn->n - 1` samples copiedto userspace will be uninitialized kernel data.Another culprit is `vm80xx_ai_insn_read()` in the "vm80xx" driver. Itnever returns an error, even if it fails to fill the buffer.Fix it in `do_insn_ioctl()` and `do_insnlist_ioctl()` by making surethat uninitialized parts of the allocated buffer are zeroed beforehandling each instruction.Thanks to Arnaud Lecomte for their fix to `do_insn_ioctl()`. That fixreplaced the call to `kmalloc_array()` with `kcalloc()`, but it is notalways necessary to clear the whole buffer.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Make insn_rw_emulate_bits() do insn->n samplesThe `insn_rw_emulate_bits()` function is used as a default handler for`INSN_READ` instructions for subdevices that have a handler for`INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a defaulthandler for `INSN_WRITE` instructions for subdevices that have a handlerfor `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the`INSN_READ` or `INSN_WRITE` instruction handling with a constructed`INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE`instructions are supposed to be able read or write multiple samples,indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currentlyonly handles a single sample. For `INSN_READ`, the comedi core willcopy `insn->n` samples back to user-space. (That triggered KASANkernel-infoleak errors when `insn->n` was greater than 1, but that isbeing fixed more generally elsewhere in the comedi core.)Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or returnan error, to conform to the general expectation for `INSN_READ` and`INSN_WRITE` handlers.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not assert we found block group item when creating free space treeCurrently, when building a free space tree at populate_free_space_tree(),if we are not using the block group tree feature, we always expect to findblock group items (either extent items or a block group item with key typeBTRFS_BLOCK_GROUP_ITEM_KEY) when we search the extent tree withbtrfs_search_slot_for_read(), so we assert that we found an item. Howeverthis expectation is wrong since we can have a new block group created inthe current transaction which is still empty and for which we still havenot added the block group's item to the extent tree, in which case we donot have any items in the extent tree associated to the block group.The insertion of a new block group's block group item in the extent treehappens at btrfs_create_pending_block_groups() when it calls the helperinsert_block_group_item(). This typically is done when a transactionhandle is released, committed or when running delayed refs (either aspart of a transaction commit or when serving tickets for space reservationif we are low on free space).So remove the assertion at populate_free_space_tree() even when the blockgroup tree feature is not enabled and update the comment to mention thiscase.Syzbot reported this with the following stack trace: BTRFS info (device loop3 state M): rebuilding free space tree assertion failed: ret == 0 :: 0, in fs/btrfs/free-space-tree.c:1115 ------------[ cut here ]------------ kernel BUG at fs/btrfs/free-space-tree.c:1115!

Description: In the Linux kernel, the following vulnerability has been resolved:exfat: validate cluster allocation bits of the allocation bitmapsyzbot created an exfat image with cluster bits not set for the allocationbitmap. exfat-fs reads and uses the allocation bitmap without checkingthis. The problem is that if the start cluster of the allocation bitmapis 6, cluster 6 can be allocated when creating a directory with mkdir.exfat zeros out this cluster in exfat_mkdir, which can delete existingentries. This can reallocate the allocated entries. In addition,the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.This patch adds exfat_test_bitmap_range to validate that clusters used forthe allocation bitmap are correctly marked as in-use.

Description: In the Linux kernel, the following vulnerability has been resolved:futex: Don't leak robust_list pointer on exec racesys_get_robust_list() and compat_get_robust_list() use ptrace_may_access()to check if the calling task is allowed to access another task'srobust_list pointer. This check is racy against a concurrent exec() in thetarget process.During exec(), a task may transition from a non-privileged binary to aprivileged one (e.g., setuid binary) and its credentials/memory mappingsmay change. If get_robust_list() performs ptrace_may_access() beforethis transition, it may erroneously allow access to sensitive informationafter the target becomes privileged.A racy access allows an attacker to exploit a window during whichptrace_may_access() passes before a target process transitions to aprivileged state via exec().For example, consider a non-privileged task T that is about to execute asetuid-root binary. An attacker task A calls get_robust_list(T) while Tis still unprivileged. Since ptrace_may_access() checks permissionsbased on current credentials, it succeeds. However, if T begins execimmediately afterwards, it becomes privileged and may change its memorymappings. Because get_robust_list() proceeds to access T->robust_listwithout synchronizing with exec() it may read user-space pointers from anow-privileged process.This violates the intended post-exec access restrictions and couldexpose sensitive memory addresses or be used as a primitive in a largerexploit chain. Consequently, the race can lead to unauthorizeddisclosure of information across privilege boundaries and poses apotential security risk.Take a read lock on signal->exec_update_lock prior to invokingptrace_may_access() and accessing the robust_list/compat_robust_list.This ensures that the target task's exec state remains stable during thecheck, allowing for consistent and synchronized validation ofcredentials.

Description: In the Linux kernel, the following vulnerability has been resolved:nfs4_setup_readdir(): insufficient locking for ->d_parent->d_inode dereferencingTheoretically it's an oopsable race, but I don't believe one can manageto hit it on real hardware; might become doable on a KVM, but it stillwon't be easy to attack.Anyway, it's easy to deal with - since xdr_encode_hyper() is just a call ofput_unaligned_be64(), we can put that under ->d_lock and be done with that.

Description: In the Linux kernel, the following vulnerability has been resolved:ksm: use range-walk function to jump over holes in scan_get_next_rmap_itemCurrently, scan_get_next_rmap_item() walks every page address in a VMA tolocate mergeable pages. This becomes highly inefficient when scanninglarge virtual memory areas that contain mostly unmapped regions, causingksmd to use large amount of cpu without deduplicating much pages.This patch replaces the per-address lookup with a range walk usingwalk_page_range(). The range walker allows KSM to skip over entireunmapped holes in a VMA, avoiding unnecessary lookups. This problem waspreviously discussed in [1].Consider the following test program which creates a 32 TiB mapping in thevirtual address space but only populates a single page:#include #include #include /* 32 TiB */const size_t size = 32ul * 1024 * 1024 * 1024 * 1024;int main() { char *area = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_NORESERVE | MAP_PRIVATE | MAP_ANON, -1, 0); if (area == MAP_FAILED) { perror("mmap() failed\n"); return -1; } /* Populate a single page such that we get an anon_vma. */ *area = 0; /* Enable KSM. */ madvise(area, size, MADV_MERGEABLE); pause(); return 0;}$ ./ksm-sparse &$ echo 1 > /sys/kernel/mm/ksm/run Without this patch ksmd uses 100% of the cpu for a long time (more then 1hour in my test machine) scanning all the 32 TiB virtual address spacethat contain only one mapped page. This makes ksmd essentially deadlockednot able to deduplicate anything of value. With this patch ksmd walksonly the one mapped page and skips the rest of the 32 TiB virtual addressspace, making the scan fast using little cpu.

Description: In the Linux kernel, the following vulnerability has been resolved:timers: Fix NULL function pointer race in timer_shutdown_sync()There is a race condition between timer_shutdown_sync() and timerexpiration that can lead to hitting a WARN_ON in expire_timers().The issue occurs when timer_shutdown_sync() clears the timer functionto NULL while the timer is still running on another CPU. The racescenario looks like this:CPU0 CPU1 lock_timer_base() expire_timers() base->running_timer = timer; unlock_timer_base() [call_timer_fn enter] mod_timer() ...timer_shutdown_sync()lock_timer_base()// For now, will not detach the timer but only clear its function to NULLif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base() [call_timer_fn exit] lock_timer_base() base->running_timer = NULL; unlock_timer_base() ... // Now timer is pending while its function set to NULL. // next timer trigger expire_timers() WARN_ON_ONCE(!fn) // hit ...lock_timer_base()// Now timer will detachif (base->running_timer != timer) ret = detach_if_pending(timer, base, true);if (shutdown) timer->function = NULL;unlock_timer_base()The problem is that timer_shutdown_sync() clears the timer functionregardless of whether the timer is currently running. This can leave apending timer with a NULL function pointer, which triggers theWARN_ON_ONCE(!fn) check in expire_timers().Fix this by only clearing the timer function when actually detaching thetimer. If the timer is running, leave the function pointer intact, which issafe because the timer will be properly detached when it finishes running.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: multiq3: sanitize config options in multiq3_attach()Syzbot identified an issue [1] in multiq3_attach() that induces atask timeout due to open() or COMEDI_DEVCONFIG ioctl operations,specifically, in the case of multiq3 driver.This problem arose when syzkaller managed to craft weird configurationoptions used to specify the number of channels in encoder subdevice.If a particularly great number is passed to s->n_chan inmultiq3_attach() via it->options[2], then multiple calls tomultiq3_encoder_reset() at the end of driver-specific attach() methodwill be running for minutes, thus blocking tasks and affected devicesas well.While this issue is most likely not too dangerous for real-lifedevices, it still makes sense to sanitize configuration inputs.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: gadget: udc: fix use-after-free in usb_gadget_state_workA race condition during gadget teardown can lead to a use-after-freein usb_gadget_state_work(), as reported by KASAN: BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0 Workqueue: events usb_gadget_state_workThe fundamental race occurs because a concurrent event (e.g., aninterrupt) can call usb_gadget_set_state() and schedule gadget->workat any time during the cleanup process in usb_del_gadget().Commit 399a45e5237c ("usb: gadget: core: flush gadget workqueue afterdevice removal") attempted to fix this by moving flush_work() to afterdevice_del(). However, this does not fully solve the race, as a newwork item can still be scheduled *after* flush_work() completes butbefore the gadget's memory is freed, leading to the same use-after-free.This patch fixes the race condition robustly by introducing a 'teardown'flag and a 'state_lock' spinlock to the usb_gadget struct. The flag isset during cleanup in usb_del_gadget() *before* calling flush_work() toprevent any new work from being scheduled once cleanup has commenced.The scheduling site, usb_gadget_set_state(), now checks this flag underthe lock before queueing the work, thus safely closing the race window.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix racy bitfield write in btrfs_clear_space_info_full()From the memory-barriers.txt document regarding memory barrier orderingguarantees: (*) These guarantees do not apply to bitfields, because compilers often generate code to modify these using non-atomic read-modify-write sequences. Do not attempt to use bitfields to synchronize parallel algorithms. (*) Even in cases where bitfields are protected by locks, all fields in a given bitfield must be protected by one lock. If two fields in a given bitfield are protected by different locks, the compiler's non-atomic read-modify-write sequences can cause an update to one field to corrupt the value of an adjacent field.btrfs_space_info has a bitfield sharing an underlying word consisting ofthe fields full, chunk_alloc, and flush:struct btrfs_space_info { struct btrfs_fs_info * fs_info; /* 0 8 */ struct btrfs_space_info * parent; /* 8 8 */ ... int clamp; /* 172 4 */ unsigned int full:1; /* 176: 0 4 */ unsigned int chunk_alloc:1; /* 176: 1 4 */ unsigned int flush:1; /* 176: 2 4 */ ...Therefore, to be safe from parallel read-modify-writes losing a write toone of the bitfield members protected by a lock, all writes to all thebitfields must use the lock. They almost universally do, except forbtrfs_clear_space_info_full() which iterates over the space_infos andwrites out found->full = 0 without a lock.Imagine that we have one thread completing a transaction in which wefinished deleting a block_group and are thus callingbtrfs_clear_space_info_full() while simultaneously the data reclaimticket infrastructure is running do_async_reclaim_data_space(): T1 T2btrfs_commit_transaction btrfs_clear_space_info_full data_sinfo->full = 0 READ: full:0, chunk_alloc:0, flush:1 do_async_reclaim_data_space(data_sinfo) spin_lock(&space_info->lock); if(list_empty(tickets)) space_info->flush = 0; READ: full: 0, chunk_alloc:0, flush:1 MOD/WRITE: full: 0, chunk_alloc:0, flush:0 spin_unlock(&space_info->lock); return; MOD/WRITE: full:0, chunk_alloc:0, flush:1and now data_sinfo->flush is 1 but the reclaim worker has exited. Thisbreaks the invariant that flush is 0 iff there is no work queued orrunning. Once this invariant is violated, future allocations that gointo __reserve_bytes() will add tickets to space_info->tickets but willsee space_info->flush is set to 1 and not queue the work. After this,they will block forever on the resulting ticket, as it is now impossibleto kick the worker again.I also confirmed by looking at the assembly of the affected kernel thatit is doing RMW operations. For example, to set the flush (3rd) bit to 0,the assembly is: andb $0xfb,0x60(%rbx)and similarly for setting the full (1st) bit to 0: andb $0xfe,-0x20(%rax)So I think this is really a bug on practical systems. I have observeda number of systems in this exact state, but am currently unable toreproduce it.Rather than leaving this footgun lying around for the future, takeadvantage of the fact that there is room in the struct anyway, and thatit is already quite large and simply change the three bitfield members tobools. This avoids writes to space_info->full having any effect on---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:sched/deadline: only set free_cpus for online runqueuesCommit 16b269436b72 ("sched/deadline: Modify cpudl::free_cpusto reflect rd->online") introduced the cpudl_set/clear_freecpufunctions to allow the cpu_dl::free_cpus mask to be manipulatedby the deadline scheduler class rq_on/offline callbacks so themask would also reflect this state.Commit 9659e1eeee28 ("sched/deadline: Remove cpu_active_maskfrom cpudl_find()") removed the check of the cpu_active_mask tosave some processing on the premise that the cpudl::free_cpusmask already reflected the runqueue online state.Unfortunately, there are cases where it is possible for thecpudl_clear function to set the free_cpus bit for a CPU when thedeadline runqueue is offline. When this occurs while a CPU isconnected to the default root domain the flag may retain the badstate after the CPU has been unplugged. Later, a different CPUthat is transitioning through the default root domain may push adeadline task to the powered down CPU when cpudl_find sees itsfree_cpus bit is set. If this happens the task will not have theopportunity to run.One example is outlined here:https://lore.kernel.org/lkml/20250110233010.2339521-1-opendmb@gmail.comAnother occurs when the last deadline task is migrated from aCPU that has an offlined runqueue. The dequeue_task member ofthe deadline scheduler class will eventually call cpudl_clearand set the free_cpus bit for the CPU.This commit modifies the cpudl_clear function to be aware of theonline state of the deadline runqueue so that the free_cpus maskcan be updated appropriately.It is no longer necessary to manage the mask outside of thecpudl_set/clear functions so the cpudl_set/clear_freecpufunctions are removed. In addition, since the free_cpus mask isnow only updated under the cpudl lock the code was changed touse the non-atomic __cpumask functions.

During device detachment, the original implementationcalls flush_workqueue() in psmouse_disconnect() to ensurecompletion of dev3_register_work. However, the flush_workqueue()in psmouse_disconnect() only blocks and waits for work items thatwere already queued to the workqueue prior to its invocation. Anywork items submitted after flush_workqueue() is called are notincluded in the set of tasks that the flush operation awaits.This means that after flush_workqueue() has finished executing,the dev3_register_work could still be scheduled. Although thepsmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(),the scheduling of dev3_register_work remains unaffected.The race condition can occur as follows:CPU 0 (cleanup path) | CPU 1 (delayed work)psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USEAdd disable_delayed_work_sync() in alps_disconnect() to ensurethat dev3_register_work is properly canceled and prevented fromexecuting after the alps_data structure has been deallocated.This bug is identified by static analysis.

Setting t->paused is leftto __submit_request() which is fine for regular requests but doesn'twork for linger requests -- since __submit_request() doesn't operateon linger requests, there is nowhere for lreq->t.paused to be set.One consequence of this is that watches don't get reestablished onpaused -> unpaused transitions in cases where requests have been pausedlong enough for the (paused) unwatch request to time out and for thesubsequent (re)watch request to enter the paused state. On top of thewatch not getting reestablished, rbd_reregister_watch() gets stuck withrbd_dev->watch_mutex held: rbd_register_watch __rbd_register_watch ceph_osdc_watch linger_reg_commit_waitIt's waiting for lreq->reg_commit_wait to be completed, but for that tohappen the respective request needs to end up on need_resend_linger listand be kicked when requests are unpaused. There is no chance for thatif the request in question is never marked paused in the first place.The fact that rbd_dev->watch_mutex remains taken out forever thenprevents the image from getting unmapped -- "rbd unmap" would inevitablyhang in D state on an attempt to grab the mutex.

Description: In the Linux kernel, the following vulnerability has been resolved:can: esd_usb: esd_usb_read_bulk_callback(): fix URB memory leakFix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:gs_usb_receive_bulk_callback(): fix URB memory leak").In esd_usb_open(), the URBs for USB-in transfers are allocated, added tothe dev->rx_submitted anchor and submitted. In the complete callbackesd_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inesd_usb_close() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in esd_usb_close().Fix the memory leak by anchoring the URB in theesd_usb_read_bulk_callback() to the dev->rx_submitted anchor.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvlan: Make the addrs_lock be per portMake the addrs_lock be per port, not per ipvlan dev.Initial code seems to be written in the assumption,that any address change must occur under RTNL.But it is not so for the case of IPv6. So1) Introduce per-port addrs_lock.2) It was needed to fix places where it was forgottento take lock (ipvlan_open/ipvlan_close)This appears to be a very minor problem though.Since it's highly unlikely that ipvlan_add_addr() willbe called on 2 CPU simultaneously. But nevertheless,this could cause:1) False-negative of ipvlan_addr_busy(): one interfaceiterated through all port->ipvlans + ipvlan->addrsunder some ipvlan spinlock, and another added IPunder its own lock. Though this is only possiblefor IPv6, since looks like only ipvlan_addr6_event() can becalled without rtnl_lock.2) Race since ipvlan_ht_addr_add(port) is called underdifferent ipvlan->addrs_lock locksThis should not affect performance, since add/remove IPis a rare situation and spinlock is not taken on fastpaths.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not strictly require dirty metadata threshold for metadata writepages[BUG]There is an internal report that over 1000 processes arewaiting at the io_schedule_timeout() of balance_dirty_pages(), causinga system hang and trigger a kernel coredump.The kernel is v6.4 kernel based, but the root problem still applies toany upstream kernel before v6.18.[CAUSE]From Jan Kara for his wisdom on the dirty page balance behavior first. This cgroup dirty limit was what was actually playing the role here because the cgroup had only a small amount of memory and so the dirty limit for it was something like 16MB. Dirty throttling is responsible for enforcing that nobody can dirty (significantly) more dirty memory than there's dirty limit. Thus when a task is dirtying pages it periodically enters into balance_dirty_pages() and we let it sleep there to slow down the dirtying. When the system is over dirty limit already (either globally or within a cgroup of the running task), we will not let the task exit from balance_dirty_pages() until the number of dirty pages drops below the limit. So in this particular case, as I already mentioned, there was a cgroup with relatively small amount of memory and as a result with dirty limit set at 16MB. A task from that cgroup has dirtied about 28MB worth of pages in btrfs btree inode and these were practically the only dirty pages in that cgroup.So that means the only way to reduce the dirty pages of that cgroup isto writeback the dirty pages of btrfs btree inode, and only after thatthose processes can exit balance_dirty_pages().Now back to the btrfs part, btree_writepages() is responsible forwriting back dirty btree inode pages.The problem here is, there is a btrfs internal threshold that if thebtree inode's dirty bytes are below the 32M threshold, it will notdo any writeback.This behavior is to batch as much metadata as possible so we won't writeback those tree blocks and then later re-COW them again for anothermodification.This internal 32MiB is higher than the existing dirty page size (28MiB),meaning no writeback will happen, causing a deadlock between btrfs andcgroup:- Btrfs doesn't want to write back btree inode until more dirty pages- Cgroup/MM doesn't want more dirty pages for btrfs btree inode Thus any process touching that btree inode is put into sleep until the number of dirty pages is reduced.Thanks Jan Kara a lot for the analysis of the root cause.[ENHANCEMENT]Since kernel commit b55102826d7d ("btrfs: set AS_KERNEL_FILE on thebtree_inode"), btrfs btree inode pages will only be charged to the rootcgroup which should have a much larger limit than btrfs' 32MiBthreshold.So it should not affect newer kernels.But for all current LTS kernels, they are all affected by this problem,and backporting the whole AS_KERNEL_FILE may not be a good idea.Even for newer kernels I still think it's a good idea to getrid of the internal threshold at btree_writepages(), since for most casescgroup/MM has a better view of full system memory usage than btrfs' fixedthreshold.For internal callers using btrfs_btree_balance_dirty() since thatfunction is already doing internal threshold check, we don't need tobother them.But for external callers of btree_writepages(), just respect theirrequests and write back whatever they want, ignoring the internalbtrfs threshold to avoid such deadlock on btree inode dirty pagebalancing.

Description: In the Linux kernel, the following vulnerability has been resolved:rocker: fix memory leak in rocker_world_port_post_fini()In rocker_world_port_pre_init(), rocker_port->wpriv is allocated withkzalloc(wops->port_priv_size, GFP_KERNEL). However, inrocker_world_port_post_fini(), the memory is only freed whenwops->port_post_fini callback is set: if (!wops->port_post_fini) return; wops->port_post_fini(rocker_port); kfree(rocker_port->wpriv);Since rocker_ofdpa_ops does not implement port_post_fini callback(it is NULL), the wpriv memory allocated for each port is never freedwhen ports are removed. This leads to a memory leak ofsizeof(struct ofdpa_port) bytes per port on every device removal.Fix this by always calling kfree(rocker_port->wpriv) regardless ofwhether the port_post_fini callback exists.

Description: In the Linux kernel, the following vulnerability has been resolved:gve: fix incorrect buffer cleanup in gve_tx_clean_pending_packets for QPLIn DQ-QPL mode, gve_tx_clean_pending_packets() incorrectly uses the RDAbuffer cleanup path. It iterates num_bufs times and attempts to unmapentries in the dma array.This leads to two issues:1. The dma array shares storage with tx_qpl_buf_ids (union). Interpreting buffer IDs as DMA addresses results in attempting to unmap incorrect memory locations.2. num_bufs in QPL mode (counting 2K chunks) can significantly exceed the size of the dma array, causing out-of-bounds access warnings(trace below is how we noticed this issue).UBSAN: array-index-out-of-bounds indrivers/net/ethernet/drivers/net/ethernet/google/gve/gve_tx_dqo.c:178:5 index 18 is out ofrange for type 'dma_addr_t[18]' (aka 'unsigned long long[18]')Workqueue: gve gve_service_task [gve]Call Trace:dump_stack_lvl+0x33/0xa0__ubsan_handle_out_of_bounds+0xdc/0x110gve_tx_stop_ring_dqo+0x182/0x200 [gve]gve_close+0x1be/0x450 [gve]gve_reset+0x99/0x120 [gve]gve_service_task+0x61/0x100 [gve]process_scheduled_works+0x1e9/0x380Fix this by properly checking for QPL mode and delegating togve_free_tx_qpl_bufs() to reclaim the buffers.

Description: In the Linux kernel, the following vulnerability has been resolved:ice: Fix memory leak in ice_set_ringparam()In ice_set_ringparam, tx_rings and xdp_rings are allocated beforerx_rings. If the allocation of rx_rings fails, the code jumps tothe done label leaking both tx_rings and xdp_rings. Furthermore, ifthe setup of an individual Rx ring fails during the loop, the code jumpsto the free_tx label which releases tx_rings but leaks xdp_rings.Fix this by introducing a free_xdp label and updating the error paths toensure both xdp_rings and tx_rings are properly freed if rx_ringsallocation or setup fails.Compile tested only.

Although the previous multiplication overflow checkprevents out-of-bounds allocation, a large number of entries could stillcause excessive memory allocation (up to potentially gigabytes) andunnecessarily long list processing times.Introduce a hard limit of 128k entries per BO list, which is more thansufficient for any realistic use case (e.g., a single list containing allbuffers in a large scene). This prevents memory exhaustion attacks andensures predictable performance.Return -EINVAL if the requested entry count exceeds the limit(cherry picked from commit 688b87d39e0aa8135105b40dc167d74b5ada5332)

Description: Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility function uses a predictable filename when extracting files from zip archives into the system temporary directory. If the target file already exists, it is reused without validation. A local attacker with write access to the temp directory could pre-create a malicious file that would be loaded in place of the legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set `TMPDIR` in their environment to a directory with restricted write access.

Description: systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.

Description: In the Linux kernel, the following vulnerability has been resolved:net: atm: fix crash due to unvalidated vcc pointer in sigd_send()Reproducer available at [1].The ATM send path (sendmsg -> vcc_sendmsg -> sigd_send) reads the vccpointer from msg->vcc and uses it directly without any validation. Thispointer comes from userspace via sendmsg() and can be arbitrarily forged: int fd = socket(AF_ATMSVC, SOCK_DGRAM, 0); ioctl(fd, ATMSIGD_CTRL); // become ATM signaling daemon struct msghdr msg = { .msg_iov = &iov, ... }; *(unsigned long *)(buf + 4) = 0xdeadbeef; // fake vcc pointer sendmsg(fd, &msg, 0); // kernel dereferences 0xdeadbeefIn normal operation, the kernel sends the vcc pointer to the signalingdaemon via sigd_enq() when processing operations like connect(), bind(),or listen(). The daemon is expected to return the same pointer whenresponding. However, a malicious daemon can send arbitrary pointer values.Fix this by introducing find_get_vcc() which validates the pointer bysearching through vcc_hash (similar to how sigd_close() iterates overall VCCs), and acquires a reference via sock_hold() if found.Since struct atm_vcc embeds struct sock as its first member, they sharethe same lifetime. Therefore using sock_hold/sock_put is sufficient tokeep the vcc alive while it is being used.Note that there may be a race with sigd_close() which could mark the vccwith various flags (e.g., ATM_VF_RELEASED) after find_get_vcc() returns.However, sock_hold() guarantees the memory remains valid, so this raceonly affects the logical state, not memory safety.[1]: https://gist.github.com/mrpre/1ba5949c45529c511152e2f4c755b0f3

Because NF_ARP_OUT == 1 == NF_INET_LOCAL_IN, the .hooksvalidation silently passes for the wrong reasons, allowing matches torun on ARP chains where the hook assumptions (e.g. state->in beingset on input hooks) do not hold.

Description: In the Linux kernel, the following vulnerability has been resolved:rds: ib: reject FRMR registration before IB connection is establishedrds_ib_get_mr() extracts the rds_ib_connection from conn->c_transport_dataand passes it to rds_ib_reg_frmr() for FRWR memory registration. On afresh outgoing connection, ic is allocated in rds_ib_conn_alloc() withi_cm_id = NULL because the connection worker has not yet calledrds_ib_conn_path_connect() to create the rdma_cm_id. When sendmsg() withRDS_CMSG_RDMA_MAP is called on such a connection, the sendmsg path parsesthe control message before any connection establishment, allowingrds_ib_post_reg_frmr() to dereference ic->i_cm_id->qp and crash thekernel.The existing guard in rds_ib_reg_frmr() only checks for !ic (added incommit 9e630bcb7701), which does not catch this case since ic is allocatedearly and is always non-NULL once the connection object exists.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nfnetlink_log: fix uninitialized padding leak in NFULA_PAYLOAD__build_packet_message() manually constructs the NFULA_PAYLOAD netlinkattribute using skb_put() and skb_copy_bits(), bypassing the standardnla_reserve()/nla_put() helpers. While nla_total_size(data_len) bytesare allocated (including NLA alignment padding), only data_len bytesof actual packet data are copied. The trailing nla_padlen(data_len)bytes (1-3 when data_len is not 4-byte aligned) are never initialized,leaking stale heap contents to userspace via the NFLOG netlink socket.Replace the manual attribute construction with nla_reserve(), whichhandles the tailroom check, header setup, and padding zeroing via__nla_reserve(). The subsequent skb_copy_bits() fills in the payloaddata on top of the properly initialized attribute.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: validate p_idx bounds in ext4_ext_correct_indexesext4_ext_correct_indexes() walks up the extent tree correctingindex entries when the first extent in a leaf is modified. Beforeaccessing path[k].p_idx->ei_block, there is no validation thatp_idx falls within the valid range of index entries for thatlevel.If the on-disk extent header contains a corrupted or craftedeh_entries value, p_idx can point past the end of the allocatedbuffer, causing a slab-out-of-bounds read.Fix this by validating path[k].p_idx against EXT_LAST_INDEX() atboth access sites: before the while loop and inside it. Return-EFSCORRUPTED if the index pointer is out of range, consistentwith how other bounds violations are handled in the ext4 extenttree code.

Description: In the Linux kernel, the following vulnerability has been resolved:hwmon: (pmbus/core) Protect regulator operations with mutexThe regulator operations pmbus_regulator_get_voltage(),pmbus_regulator_set_voltage(), and pmbus_regulator_list_voltage()access PMBus registers and shared data but were not protected bythe update_lock mutex. This could lead to race conditions.However, adding mutex protection directly to these functions causesa deadlock because pmbus_regulator_notify() (which callsregulator_notifier_call_chain()) is often called with the mutexalready held (e.g., from pmbus_fault_handler()). If a regulatorcallback then calls one of the now-protected voltage functions,it will attempt to acquire the same mutex.Rework pmbus_regulator_notify() to utilize a worker function tosend notifications outside of the mutex protection. Events arestored as atomics in a per-page bitmask and processed by the worker.Initialize the worker and its associated data during regulatorregistration, and ensure it is cancelled on device removal usingdevm_add_action_or_reset().While at it, remove the unnecessary include of linux/of.h.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: set BTRFS_ROOT_ORPHAN_CLEANUP during subvol createWe have recently observed a number of subvolumes with broken dentries.ls-ing the parent dir looks like:drwxrwxrwt 1 root root 16 Jan 23 16:49 .drwxr-xr-x 1 root root 24 Jan 23 16:48 ..d????????? ? ? ? ? ? broken_subvoland similarly stat-ing the file fails.In this state, deleting the subvol fails with ENOENT, but attempting tocreate a new file or subvol over it errors out with EEXIST and evenaborts the fs. Which leaves us a bit stuck.dmesg contains a single notable error message reading:"could not do orphan cleanup -2"2 is ENOENT and the error comes from the failure handling path ofbtrfs_orphan_cleanup(), with the stack leading back up tobtrfs_lookup().btrfs_lookupbtrfs_lookup_dentrybtrfs_orphan_cleanup // prints that message and returns -ENOENTAfter some detailed inspection of the internal state, it became clearthat:- there are no orphan items for the subvol- the subvol is otherwise healthy looking, it is not half-deleted or anything, there is no drop progress, etc.- the subvol was created a while ago and does the meaningful first btrfs_orphan_cleanup() call that sets BTRFS_ROOT_ORPHAN_CLEANUP much later.- after btrfs_orphan_cleanup() fails, btrfs_lookup_dentry() returns -ENOENT, which results in a negative dentry for the subvolume via d_splice_alias(NULL, dentry), leading to the observed behavior. The bug can be mitigated by dropping the dentry cache, at which point we can successfully delete the subvolume if we want.i.e.,btrfs_lookup() btrfs_lookup_dentry() if (!sb_rdonly(inode->vfs_inode)->vfs_inode) btrfs_orphan_cleanup(sub_root) test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP) btrfs_search_slot() // finds orphan item for inode N ... prints "could not do orphan cleanup -2" if (inode == ERR_PTR(-ENOENT)) inode = NULL; return d_splice_alias(NULL, dentry) // NEGATIVE DENTRY for valid subvolumebtrfs_orphan_cleanup() does test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)on the root when it runs, so it cannot run more than once on a givenroot, so something else must run concurrently. However, the obviousroutes to deleting an orphan when nlinks goes to 0 should not be able torun without first doing a lookup into the subvolume, which should runbtrfs_orphan_cleanup() and set the bit.The final important observation is that create_subvol() callsd_instantiate_new() but does not set BTRFS_ROOT_ORPHAN_CLEANUP, so ifthe dentry cache gets dropped, the next lookup into the subvolume willmake a real call into btrfs_orphan_cleanup() for the first time. Thisopens up the possibility of concurrently deleting the inode/orphan itemsbut most typical evict() paths will be holding a reference on the parentdentry (child dentry holds parent->d_lockref.count via dget ind_alloc(), released in __dentry_kill()) and prevent the parent frombeing removed from the dentry cache.The one exception is delayed iputs. Ordered extent creation callsigrab() on the inode. If the file is unlinked and closed while thoserefs are held, iput() in __dentry_kill() decrements i_count but doesnot trigger eviction (i_count > 0). The child dentry is freed and thesubvol dentry's d_lockref.count drops to 0, making it evictable whilethe inode is still alive.Since there are two races (the race between writeback and unlink andthe race between lookup and delayed iputs), and there are too many movingparts, the following three diagrams show the complete picture.(Only the second and third are races)Phase 1:Create Subvol in dentry cache without BTRFS_ROOT_ORPHAN_CLEANUP setbtrfs_mksubvol() lookup_one_len() __lookup_slow() d_alloc_parallel() __d_alloc() // d_lockref.count = 1 create_subvol(dentry) // doesn't touch the bit.. d_instantiate_new(dentry, inode) // dentry in cache with d_lockref.c---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:media: hackrf: fix to not free memory after the device is registered in hackrf_probe()In hackrf driver, the following race condition occurs:``` CPU0 CPU1hackrf_probe() kzalloc(); // alloc hackrf_dev .... v4l2_device_register(); .... fd = sys_open("/path/to/dev"); // open hackrf fd .... v4l2_device_unregister(); .... kfree(); // free hackrf_dev .... sys_ioctl(fd, ...); v4l2_ioctl(); video_is_registered() // UAF!! .... sys_close(fd); v4l2_release() // UAF!! hackrf_video_release() kfree(); // DFB!!```When a V4L2 or video device is unregistered, the device node is removed sonew open() calls are blocked.However, file descriptors that are already open-and any in-flight I/O-donot terminate immediately; they remain valid until the last reference isdropped and the driver's release() is invoked.Therefore, freeing device memory on the error path after hackrf_probe()has registered dev it will lead to a race to use-after-free vuln, sincethose already-open handles haven't been released yet.And since release() free memory too, race to use-after-free anddouble-free vuln occur.To prevent this, if device is registered from probe(), it should bemodified to free memory only through release() rather than callingkfree() directly.

Description: In the Linux kernel, the following vulnerability has been resolved:media: as102: fix to not free memory after the device is registered in as102_usb_probe()In as102_usb driver, the following race condition occurs:``` CPU0 CPU1as102_usb_probe() kzalloc(); // alloc as102_dev_t .... usb_register_dev(); fd = sys_open("/path/to/dev"); // open as102 fd .... usb_deregister_dev(); .... kfree(); // free as102_dev_t .... sys_close(fd); as102_release() // UAF!! as102_usb_release() kfree(); // DFB!!```When a USB character device registered with usb_register_dev() is laterunregistered (via usb_deregister_dev() or disconnect), the device node isremoved so new open() calls fail. However, file descriptors that arealready open do not go away immediately: they remain valid until the lastreference is dropped and the driver's .release() is invoked.In as102, as102_usb_probe() calls usb_register_dev() and then, on anerror path, does usb_deregister_dev() and frees as102_dev_t right away.If userspace raced a successful open() before the deregistration, thatopen FD will later hit as102_release() --> as102_usb_release() and accessor free as102_dev_t again, occur a race to use-after-free anddouble-free vuln.The fix is to never kfree(as102_dev_t) directly once usb_register_dev()has succeeded. After deregistration, defer freeing memory to .release().In other words, let release() perform the last kfree when the final openFD is closed.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: SEV: Drop WARN on large size for KVM_MEMORY_ENCRYPT_REG_REGIONDrop the WARN in sev_pin_memory() on npages overflowing an int, as theWARN is comically trivially to trigger from userspace, e.g. by doing: struct kvm_enc_region range = { .addr = 0, .size = -1ul, }; __vm_ioctl(vm, KVM_MEMORY_ENCRYPT_REG_REGION, &range);Note, the checks in sev_mem_enc_register_region() that presumably exist toverify the incoming address+size are completely worthless, as both "addr"and "size" are u64s and SEV is 64-bit only, i.e. they _can't_ be greaterthan ULONG_MAX. That wart will be cleaned up in the near future. if (range->addr > ULONG_MAX || range->size > ULONG_MAX) return -EINVAL;Opportunistically add a comment to explain why the code calculates thenumber of pages the "hard" way, e.g. instead of just shifting @ulen.

But until commita166563e7ec37 ("arm64: mm: support large block mapping whenrodata=full") large leaf mappings were never made invalid in this way.It turns out various parts of the code base are not equipped to handleinvalid large leaf mappings (in the way they are currently encoded) andI've observed a kernel panic while booting a realm guest on aBBML2_NOABORT system as a result:[ 15.432706] software IO TLB: Memory encryption is active and system is using DMA bounce buffers[ 15.476896] Unable to handle kernel paging request at virtual address ffff000019600000[ 15.513762] Mem abort info:[ 15.527245] ESR = 0x0000000096000046[ 15.548553] EC = 0x25: DABT (current EL), IL = 32 bits[ 15.572146] SET = 0, FnV = 0[ 15.592141] EA = 0, S1PTW = 0[ 15.612694] FSC = 0x06: level 2 translation fault[ 15.640644] Data abort info:[ 15.661983] ISV = 0, ISS = 0x00000046, ISS2 = 0x00000000[ 15.694875] CM = 0, WnR = 1, TnD = 0, TagAccess = 0[ 15.723740] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0[ 15.755776] swapper pgtable: 4k pages, 48-bit VAs, pgdp=0000000081f3f000[ 15.800410] [ffff000019600000] pgd=0000000000000000, p4d=180000009ffff403, pud=180000009fffe403, pmd=00e8000199600704[ 15.855046] Internal error: Oops: 0000000096000046 [#1] SMP[ 15.886394] Modules linked in:[ 15.900029] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 7.0.0-rc4-dirty #4 PREEMPT[ 15.935258] Hardware name: linux,dummy-virt (DT)[ 15.955612] pstate: 21400005 (nzCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)[ 15.986009] pc : __pi_memcpy_generic+0x128/0x22c[ 16.006163] lr : swiotlb_bounce+0xf4/0x158[ 16.024145] sp : ffff80008000b8f0[ 16.038896] x29: ffff80008000b8f0 x28: 0000000000000000 x27: 0000000000000000[ 16.069953] x26: ffffb3976d261ba8 x25: 0000000000000000 x24: ffff000019600000[ 16.100876] x23: 0000000000000001 x22: ffff0000043430d0 x21: 0000000000007ff0[ 16.131946] x20: 0000000084570010 x19: 0000000000000000 x18: ffff00001ffe3fcc[ 16.163073] x17: 0000000000000000 x16: 00000000003fffff x15: 646e612065766974[ 16.194131] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000[ 16.225059] x11: 0000000000000000 x10: 0000000000000010 x9 : 0000000000000018[ 16.256113] x8 : 0000000000000018 x7 : 0000000000000000 x6 : 0000000000000000[ 16.287203] x5 : ffff000019607ff0 x4 : ffff000004578000 x3 : ffff000019600000[ 16.318145] x2 : 0000000000007ff0 x1 : ffff000004570010 x0 : ffff000019600000[ 16.349071] Call trace:[ 16.360143] __pi_memcpy_generic+0x128/0x22c (P)[ 16.380310] swiotlb_tbl_map_single+0x154/0x2b4[ 16.400282] swiotlb_map+0x5c/0x228[ 16.415984] dma_map_phys+0x244/0x2b8[ 16.432199] dma_map_page_attrs+0x44/0x58[ 16.449782] virtqueue_map_page_attrs+0x38/0x44[ 16.469596] virtqueue_map_single_attrs+0xc0/0x130[ 16.490509] virtnet_rq_alloc.isra.0+0xa4/0x1fc[ 16.510355] try_fill_recv+0x2a4/0x584[ 16.526989] virtnet_open+0xd4/0x238[ 16.542775] __dev_open+0x110/0x24c[ 16.558280] __dev_change_flags+0x194/0x20c[ 16.576879] netif_change_flags+0x24/0x6c[ 16.594489] dev_change_flags+0x48/0x7c[ 16.611462] ip_auto_config+0x258/0x1114[ 16.628727] do_one_initcall+0x80/0x1c8[ 16.645590] kernel_init_freeable+0x208/0x2f0[ 16.664917] kernel_init+0x24/0x1e0[ 16.680295] ret_from_fork+0x10/0x20[ 16.696369] Code: 927cec03 cb0e0021 8b0e0042 a9411c26 (a900340c)[ 16.723106] ---[ end trace 0000000000000000 ]---[ 16.752866] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b[ 16.792556] Kernel Offset: 0x3396ea200000 from 0xffff8000800000---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:HID: core: clamp report_size in s32ton() to avoid undefined shifts32ton() shifts by n-1 where n is the field's report_size, a value thatcomes directly from a HID device. The HID parser bounds report_sizeonly to <= 256, so a broken HID device can supply a report descriptorwith a wide field that triggers shift exponents up to 256 on a 32-bittype when an output report is built via hid_output_field() orhid_set_field().Commit ec61b41918587 ("HID: core: fix shift-out-of-bounds inhid_report_raw_event") added the same n > 32 clamp to the functionsnto32(), but s32ton() was never given the same fix as I guess syzbothadn't figured out how to fuzz a device the same way.Fix this up by just clamping the max value of n, just like snto32()does.

Description: In the Linux kernel, the following vulnerability has been resolved:rxrpc: proc: size address buffers for %pISpc outputThe AF_RXRPC procfs helpers format local and remote socket addresses intofixed 50-byte stack buffers with "%pISpc".That is too small for the longest current-tree IPv6-with-port form theformatter can produce. In lib/vsprintf.c, the compressed IPv6 path uses adotted-quad tail not only for v4mapped addresses, but also for ISATAPaddresses via ipv6_addr_is_isatap().As a result, a case such as [ffff:ffff:ffff:ffff:0:5efe:255.255.255.255]:65535is possible with the current formatter. That is 50 visible characters, so51 bytes including the trailing NUL, which does not fit in the existingchar[50] buffers used by net/rxrpc/proc.c.Size the buffers from the formatter's maximum textual form and switch thecall sites to scnprintf().Changes since v1:- correct the changelog to cite the actual maximum current-tree case explicitly- frame the proof around the ISATAP formatting path instead of the earlier mapped-v4 example

While the XDR path (rxrpc_preparse_xdr_rxkad()) correctlyvalidates the ticket length against AFSTOKEN_RK_TIX_MAX, the non-XDRpath fails to do so.This allows an unprivileged user to provide a very large ticket length.When this key is later read via rxrpc_read(), the totaltoken size (toksize) calculation results in a value that exceedsAFSTOKEN_LENGTH_MAX, triggering a WARN_ON().[ 2001.302904] WARNING: CPU: 2 PID: 2108 at net/rxrpc/key.c:778 rxrpc_read+0x109/0x5c0 [rxrpc]Fix this by adding a check in the non-XDR parsing path of rxrpc_preparse()to ensure the ticket length does not exceed AFSTOKEN_RK_TIX_MAX,bringing it into parity with the XDR parsing logic.

Description: In the Linux kernel, the following vulnerability has been resolved:xen/privcmd: fix double free via VMA splittingprivcmd_vm_ops defines .close (privcmd_close), but neither .may_splitnor .open. When userspace does a partial munmap() on a privcmd mapping,the kernel splits the VMA via __split_vma(). Since may_split is NULL,the split is allowed. vm_area_dup() copies vm_private_data (a pagesarray allocated in alloc_empty_pages()) into the new VMA without anyfixup, because there is no .open callback.Both VMAs now point to the same pages array. When the unmapped portionis closed, privcmd_close() calls: - xen_unmap_domain_gfn_range() - xen_free_unpopulated_pages() - kvfree(pages)The surviving VMA still holds the dangling pointer. When it is laterdestroyed, the same sequence runs again, which leads to a double free.Fix this issue by adding a .may_split callback denying the VMA split.This is XSA-487 / CVE-2026-31787

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, an integer underflow vulnerability in _ppdCreateFromIPP() (cups/ppd-cache.c) allows any unprivileged local user to crash the cupsd root process by supplying a negative job-password-supported IPP attribute. The bounds check only caps the upper bound, so a negative value passes validation, is cast to size_t (wrapping to ~2^64), and is used as the length argument to memset() on a 33-byte stack buffer. This causes an immediate SIGSEGV in the cupsd root process. Combined with systemd's Restart=on-failure, an attacker can repeat the crash for sustained denial of service.

Description: OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: ctnetlink: zero expect NAT fields when CTA_EXPECT_NAT absentctnetlink_alloc_expect() allocates expectations from a non-zeroingslab cache via nf_ct_expect_alloc(). When CTA_EXPECT_NAT is notpresent in the netlink message, saved_addr and saved_proto arenever initialized. Stale data from a previous slab occupant canthen be dumped to userspace by ctnetlink_exp_dump_expect(), whichchecks these fields to decide whether to emit CTA_EXPECT_NAT.The safe sibling nf_ct_expect_init(), used by the packet path,explicitly zeroes these fields.Zero saved_addr, saved_proto and dir in the else branch, guardedby IS_ENABLED(CONFIG_NF_NAT) since these fields only exist whenNAT is enabled.Confirmed by priming the expect slab with NAT-bearing expectations,freeing them, creating a new expectation without CTA_EXPECT_NAT,and observing that the ctnetlink dump emits a spuriousCTA_EXPECT_NAT containing stale data from the prior allocation.

This value gets passed to mpls_label_ok once morein both mpls_route_add and mpls_route_del, so there is no issue, butthat additional check must not be removed.

Description: When curl is asked to use HSTS, the expiry time for a subdomain mightoverwrite a parent domain's cache entry, making it end sooner or later thanotherwise intended.This affects curl using applications that enable HSTS and use URLs with theinsecure `HTTP://` scheme and perform transfers with hosts like`x.example.com` as well as `example.com` where the first host is a subdomainof the second host.(The HSTS cache either needs to have been populated manually or there needs tohave been previous HTTPS accesses done as the cache needs to have entries forthe domains involved to trigger this problem.)When `x.example.com` responds with `Strict-Transport-Security:` headers, thisbug can make the subdomain's expiry timeout *bleed over* and get set for theparent domain `example.com` in curl's HSTS cache.The result of a triggered bug is that HTTP accesses to `example.com` getconverted to HTTPS for a different period of time than what was asked for bythe origin server. If `example.com` for example stops supporting HTTPS at itsexpiry time, curl might then fail to access `http://example.com` until the(wrongly set) timeout expires. This bug can also expire the parent's entry*earlier*, thus making curl inadvertently switch back to insecure HTTP earlierthan otherwise intended.

Description: The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a DNS packet.An attacker can craft a malicious DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the name decompression process consumes a large amount of CPU resources, as the library does not limit the resulting length of the name.This resource consumption can cause the application thread to become unresponsive, resulting in a Denial of Service condition.

Description: xz is a pure golang package for reading and writing xz-compressed files. Prior to version 0.5.14, it is possible to put data in front of an LZMA-encoded byte stream without detecting the situation while reading the header. This can lead to increased memory consumption because the current implementation allocates the full decoding buffer directly after reading the header. The LZMA header doesn't include a magic number or has a checksum to detect such an issue according to the specification. Note that the code recognizes the issue later while reading the stream, but at this time the memory allocation has already been done. This issue has been patched in version 0.5.14.

Description: urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.0 and prior to 2.6.0, the Streaming API improperly handles highly compressed data. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header (e.g., gzip, deflate, br, or zstd). The library must read compressed data from the network and decompress it until the requested chunk size is met. Any resulting decompressed data that exceeds the requested amount is held in an internal buffer for the next read operation. The decompression logic could cause urllib3 to fully decode a small amount of highly compressed data in a single operation. This can result in excessive resource consumption (high CPU usage and massive memory allocation for the decompressed data.

Description: In the Linux kernel, the following vulnerability has been resolved:atm: lec: fix null-ptr-deref in lec_arp_clear_vccssyzkaller reported a null-ptr-deref in lec_arp_clear_vccs().This issue can be easily reproduced using the syzkaller reproducer.In the ATM LANE (LAN Emulation) module, the same atm_vcc can be shared bymultiple lec_arp_table entries (e.g., via entry->vcc or entry->recv_vcc).When the underlying VCC is closed, lec_vcc_close() iterates over allARP entries and calls lec_arp_clear_vccs() for each matched entry.For example, when lec_vcc_close() iterates through the hlists inpriv->lec_arp_empty_ones or other ARP tables:1. In the first iteration, for the first matched ARP entry sharing the VCC,lec_arp_clear_vccs() frees the associated vpriv (which is vcc->user_back)and sets vcc->user_back to NULL.2. In the second iteration, for the next matched ARP entry sharing the sameVCC, lec_arp_clear_vccs() is called again. It obtains a NULL vpriv fromvcc->user_back (via LEC_VCC_PRIV(vcc)) and then attempts to dereference itvia `vcc->pop = vpriv->old_pop`, leading to a null-ptr-deref crash.Fix this by adding a null check for vpriv before dereferencingit. If vpriv is already NULL, it means the VCC has been clearedby a previous call, so we can safely skip the cleanup and justclear the entry's vcc/recv_vcc pointers.The entire cleanup block (including vcc_release_async()) is placed insidethe vpriv guard because a NULL vpriv indicates the VCC has already beenfully released by a prior iteration - repeating the teardown wouldredundantly set flags and trigger callbacks on an already-closing socket.The Fixes tag points to the initial commit because the entry->vcc path hasbeen vulnerable since the original code. The entry->recv_vcc path was lateradded by commit 8d9f73c0ad2f ("atm: fix a memory leak of vcc->user_back")with the same pattern, and both paths are fixed here.

Description: Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state->out1->out without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.

This can lead to data being accepted which may be processed differently by other implementations. Use "validate=True" to enable stricter processing of base64 data.

Description: A weakness has been identified in libssh up to 0.11.3. The impacted element is the function sftp_extensions_get_name/sftp_extensions_get_data of the file src/sftp.c of the component SFTP Extension Name Handler. Executing a manipulation of the argument idx can lead to out-of-bounds read. The attack may be performed from remote. Upgrading to version 0.11.4 and 0.12.0 is sufficient to resolve this issue. This patch is called 855a0853ad3abd4a6cd85ce06fce6d8d4c7a0b60. You should upgrade the affected component.

Description: The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory.These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: VMX: Fix crash due to uninitialized current_vmcsKVM enables 'Enlightened VMCS' and 'Enlightened MSR Bitmap' when running asa nested hypervisor on top of Hyper-V. When MSR bitmap is updated,evmcs_touch_msr_bitmap function uses current_vmcs per-cpu variable to markthat the msr bitmap was changed.vmx_vcpu_create() modifies the msr bitmap via vmx_disable_intercept_for_msr-> vmx_msr_bitmap_l01_changed which in the end calls this function. Thefunction checks for current_vmcs if it is null but the check isinsufficient because current_vmcs is not initialized. Because of this, thecode might incorrectly write to the structure pointed by current_vmcs valueleft by another task. Preemption is not disabled, the current task can bepreempted and moved to another CPU while current_vmcs is accessed multipletimes from evmcs_touch_msr_bitmap() which leads to crash.The manipulation of MSR bitmaps by callers happens only for vmcs01 so thesolution is to use vmx->vmcs01.vmcs instead of current_vmcs.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.0.9 to before 1.6.57, passing a pointer obtained from png_get_PLTE, png_get_tRNS, or png_get_hIST back into the corresponding setter on the same png_struct/png_info pair causes the setter to read from freed memory and copy its contents into the replacement buffer. The setter frees the internal buffer before copying from the caller-supplied pointer, which now dangles. The freed region may contain stale data (producing silently corrupted chunk metadata) or data from subsequent heap allocations (leaking unrelated heap contents into the chunk struct). This vulnerability is fixed in 1.6.57.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: fix i_data_sem unlock order in ext4_ind_migrate()Fuzzing reports a possible deadlock in jbd2_log_wait_commit.This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to requiresynchronous updates because the file descriptor is opened with O_SYNC.This can lead to the jbd2_journal_stop() function callingjbd2_might_wait_for_commit(), potentially causing a deadlock if theEXT4_IOC_MIGRATE call races with a write(2) system call.This problem only arises when CONFIG_PROVE_LOCKING is enabled. In thiscase, the jbd2_might_wait_for_commit macro locks jbd2_handle in thejbd2_journal_stop function while i_data_sem is locked. This triggerslockdep because the jbd2_journal_start function might also lock the samejbd2_handle simultaneously.Found by Linux Verification Center (linuxtesting.org) with syzkaller.Rule: add

Description: In the Linux kernel, the following vulnerability has been resolved:sched/rt: Fix race in push_rt_taskOverview========When a CPU chooses to call push_rt_task and picks a task to push toanother CPU's runqueue then it will call find_lock_lowest_rq methodwhich would take a double lock on both CPUs' runqueues. If one of thelocks aren't readily available, it may lead to dropping the currentrunqueue lock and reacquiring both the locks at once. During this windowit is possible that the task is already migrated and is running on someother CPU. These cases are already handled. However, if the task ismigrated and has already been executed and another CPU is now trying towake it up (ttwu) such that it is queued again on the runqeue(on_rq is 1) and also if the task was run by the same CPU, then thecurrent checks will pass even though the task was migrated out and is nolonger in the pushable tasks list.Crashes=======This bug resulted in quite a few flavors of crashes triggering kernelpanics with various crash signatures such as assert failures, pagefaults, null pointer dereferences, and queue corruption errors allcoming from scheduler itself.Some of the crashes:-> kernel BUG at kernel/sched/rt.c:1616!

Description: A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process.A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: don't log conflicting inode if it's a dir moved in the current transactionWe can't log a conflicting inode if it's a directory and it was movedfrom one parent directory to another parent directory in the currenttransaction, as this can result an attempt to have a directory withtwo hard links during log replay, one for the old parent directory andanother for the new parent directory.The following scenario triggers that issue:1) We have directories "dir1" and "dir2" created in a past transaction. Directory "dir1" has inode A as its parent directory;2) We move "dir1" to some other directory;3) We create a file with the name "dir1" in directory inode A;4) We fsync the new file. This results in logging the inode of the new file and the inode for the directory "dir1" that was previously moved in the current transaction. So the log tree has the INODE_REF item for the new location of "dir1";5) We move the new file to some other directory. This results in updating the log tree to included the new INODE_REF for the new location of the file and removes the INODE_REF for the old location. This happens during the rename when we call btrfs_log_new_name();6) We fsync the file, and that persists the log tree changes done in the previous step (btrfs_log_new_name() only updates the log tree in memory);7) We have a power failure;8) Next time the fs is mounted, log replay happens and when processing the inode for directory "dir1" we find a new INODE_REF and add that link, but we don't remove the old link of the inode since we have not logged the old parent directory of the directory inode "dir1".As a result after log replay finishes when we trigger writeback of thesubvolume tree's extent buffers, the tree check will detect that we havea directory a hard link count of 2 and we get a mount failure.The errors and stack traces reported in dmesg/syslog are like this: [ 3845.729764] BTRFS info (device dm-0): start tree-log replay [ 3845.730304] page: refcount:3 mapcount:0 mapping:000000005c8a3027 index:0x1d00 pfn:0x11510c [ 3845.731236] memcg:ffff9264c02f4e00 [ 3845.731751] aops:btree_aops [btrfs] ino:1 [ 3845.732300] flags: 0x17fffc00000400a(uptodate|private|writeback|node=0|zone=2|lastcpupid=0x1ffff) [ 3845.733346] raw: 017fffc00000400a 0000000000000000 dead000000000122 ffff9264d978aea8 [ 3845.734265] raw: 0000000000001d00 ffff92650e6d4738 00000003ffffffff ffff9264c02f4e00 [ 3845.735305] page dumped because: eb page dump [ 3845.735981] BTRFS critical (device dm-0): corrupt leaf: root=5 block=30408704 slot=6 ino=257, invalid nlink: has 2 expect no more than 1 for dir [ 3845.737786] BTRFS info (device dm-0): leaf 30408704 gen 10 total ptrs 17 free space 14881 owner 5 [ 3845.737789] BTRFS info (device dm-0): refs 4 lock_owner 0 current 30701 [ 3845.737792] item 0 key (256 INODE_ITEM 0) itemoff 16123 itemsize 160 [ 3845.737794] inode generation 3 transid 9 size 16 nbytes 16384 [ 3845.737795] block group 0 mode 40755 links 1 uid 0 gid 0 [ 3845.737797] rdev 0 sequence 2 flags 0x0 [ 3845.737798] atime 1764259517.0 [ 3845.737800] ctime 1764259517.572889464 [ 3845.737801] mtime 1764259517.572889464 [ 3845.737802] otime 1764259517.0 [ 3845.737803] item 1 key (256 INODE_REF 256) itemoff 16111 itemsize 12 [ 3845.737805] index 0 name_len 2 [ 3845.737807] item 2 key (256 DIR_ITEM 2363071922) itemoff 16077 itemsize 34 [ 3845.737808] location key (257 1 0) type 2 [ 3845.737810] transid 9 data_len 0 name_len 4 [ 3845.737811] item 3 key (256 DIR_ITEM 2676584006) itemoff 16043 itemsize 34 [ 3845.737813] location key (258 1 0) type 2 [ 3845.737814] transid 9 data_len 0 name_len 4 [ 3845.737815] item 4 key (256 DIR_INDEX 2) itemoff 16009 itemsize 34 [ 3845.737816] location key (257 1 0) type 2 [---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not free data reservation in fallback from inline due to -ENOSPCIf we fail to create an inline extent due to -ENOSPC, we will attempt togo through the normal COW path, reserve an extent, create an orderedextent, etc. However we were always freeing the reserved qgroup data,which is wrong since we will use data.

Description: In the Linux kernel, the following vulnerability has been resolved:net: add proper RCU protection to /proc/net/ptypeYin Fengwei reported an RCU stall in ptype_seq_show() and provideda patch.Real issue is that ptype_seq_next() and ptype_seq_show() violateRCU rules.ptype_seq_show() runs under rcu_read_lock(), and reads pt->devto get device name without any barrier.At the same time, concurrent writers can remove a packet_type structure(which is correctly freed after an RCU grace period) and clear pt->devwithout an RCU grace period.Define ptype_iter_state to carry a dev pointer along seq_net_private:struct ptype_iter_state { struct seq_net_private p; struct net_device *dev; // added in this patch};We need to record the device pointer in ptype_get_idx() andptype_seq_next() so that ptype_seq_show() is safe againstconcurrent pt->dev changes.We also need to add full RCU protection in ptype_seq_next().(Missing READ_ONCE() when reading list.next values)Many thanks to Dong Chenchen for providing a repro.

Description: util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privileges via fork() + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0) without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the source file with a symlink pointing to any root-owned file or device during the race window, causing the SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized read access to root-protected files and block devices, including backup images, disk volumes, and any file containing a valid filesystem. This issue has been patched in version 2.41.4.

Description: In the Linux kernel, the following vulnerability has been resolved:Input: uinput - fix circular locking dependency with ff-coreA lockdep circular locking dependency warning can be triggeredreproducibly when using a force-feedback gamepad with uinput (forexample, playing ELDEN RING under Wine with a Flydigi Vader 5controller): ff->mutex -> udev->mutex -> input_mutex -> dev->mutex -> ff->mutexThe cycle is caused by four lock acquisition paths:1. ff upload: input_ff_upload() holds ff->mutex and calls uinput_dev_upload_effect() -> uinput_request_submit() -> uinput_request_send(), which acquires udev->mutex.2. device create: uinput_ioctl_handler() holds udev->mutex and calls uinput_create_device() -> input_register_device(), which acquires input_mutex.3. device register: input_register_device() holds input_mutex and calls kbd_connect() -> input_register_handle(), which acquires dev->mutex.4. evdev release: evdev_release() calls input_flush_device() under dev->mutex, which calls input_ff_flush() acquiring ff->mutex.Fix this by introducing a new state_lock spinlock to protectudev->state and udev->dev access in uinput_request_send() instead ofacquiring udev->mutex. The function only needs to atomically checkdevice state and queue an input event into the ring buffer viauinput_dev_event() -- both operations are safe under a spinlock(ktime_get_ts64() and wake_up_interruptible() do not sleep). Thisbreaks the ff->mutex -> udev->mutex link since a spinlock is a leaf inthe lock ordering and cannot form cycles with mutexes.To keep state transitions visible to uinput_request_send(), protectwrites to udev->state in uinput_create_device() anduinput_destroy_device() with the same state_lock spinlock.Additionally, move init_completion(&request->done) fromuinput_request_send() to uinput_request_submit() beforeuinput_request_reserve_slot(). Once the slot is allocated,uinput_flush_requests() may call complete() on it at any time fromthe destroy path, so the completion must be initialised before therequest becomes visible.Lock ordering after the fix: ff->mutex -> state_lock (spinlock, leaf) udev->mutex -> state_lock (spinlock, leaf) udev->mutex -> input_mutex -> dev->mutex -> ff->mutex (no back-edge)

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: flowlabel: defer exclusive option free until RCU teardown`ip6fl_seq_show()` walks the global flowlabel hash under the seq-fileRCU read-side lock and prints `fl->opt->opt_nflen` when an option blockis present.Exclusive flowlabels currently free `fl->opt` as soon as `fl->users`drops to zero in `fl_release()`. However, the surrounding`struct ip6_flowlabel` remains visible in the global hash table untillater garbage collection removes it and `fl_free_rcu()` finally tears itdown.A concurrent `/proc/net/ip6_flowlabel` reader can therefore race thatearly `kfree()` and dereference freed option state, triggering a crashin `ip6fl_seq_show()`.Fix this by keeping `fl->opt` alive until `fl_free_rcu()`. That matchesthe lifetime already required for the enclosing flowlabel while readerscan still reach it under RCU.

Description: Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.
Packages affected:

Description: Vim is an improved version of the unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. So this may lead to the tb_off position within the typebuf variable to point outside of the valid buffer size, which can then later lead to a heap-buffer overflow in e.g. ins_typebuf(). Therefore, when flushing the typeahead buffer, check if there is enough space left before advancing the off position. If not, fall back to flush current typebuf contents. It's not quite clear yet, what can lead to this situation. It seems to happen when error messages occur (which will cause Vim to flush the typeahead buffer) in comnination with several long mappgins and so it may eventually move the off position out of a valid buffer size. Impact is low since it is not easily reproducible and requires to have several mappings active and run into some error condition. But when this happens, this will cause a crash. The issue has been fixed as of Vim patch v9.1.0697. Users are advised to upgrade. There are no known workarounds for this issue.

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: nf_conntrack_sip: fix use of uninitialized rtp_addr in process_sdpprocess_sdp() declares union nf_inet_addr rtp_addr on the stack andpasses it to the nf_nat_sip sdp_session hook after walking the SDPmedia descriptions. However rtp_addr is only initialized inside themedia loop when a recognized media type with a non-zero port is found.If the SDP body contains no m= lines, only inactive media sections(m=audio 0 ...) or only unrecognized media types, rtp_addr is neverassigned. Despite that, the function still calls hooks->sdp_session()with &rtp_addr, causing nf_nat_sdp_session() to format the stale stackvalue as an IP address and rewrite the SDP session owner and connectionlines with it.With CONFIG_INIT_STACK_ALL_ZERO (default on most distributions) thisresults in the session-level o= and c= addresses being rewritten to0.0.0.0 for inactive SDP sessions. Without stack auto-init therewritten address is whatever happened to be on the stack.Fix this by pre-initializing rtp_addr from the session-level connectionaddress (caddr) when available, and tracking via a have_rtp_addr flagwhether any valid address was established. Skip the sdp_session hookentirely when no valid address exists.

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Lock external INTx masking opsMask operations through config space changes to DisINTx may race INTxconfiguration changes via ioctl. Create wrappers that add locking forpaths outside of the core interrupt code.In particular, irq_type is updated holding igate, therefore testingis_intx() requires holding igate. For example clearing DisINTx fromconfig space can otherwise race changes of the interrupt configuration.This aligns interfaces which may trigger the INTx eventfd into twocamps, one side serialized by igate and the other only enabled whileINTx is configured. A subsequent patch introduces synchronization forthe latter flows.

Description: Vim is an open source, command line text editor. Patch v9.1.0038 optimized how the cursor position is calculated and removed a loop, that verified that the cursor position always points inside a line and does not become invalid by pointing beyond the end ofa line. Back then we assumed this loop is unnecessary. However, this change made it possible that the cursor position stays invalid and points beyond the end of a line, which would eventually cause a heap-buffer-overflow when trying to access the line pointer atthe specified cursor position. It's not quite clear yet, what can lead to this situation that the cursor points to an invalid position. That's why patch v9.1.0707 does not include a test case. The only observed impact has been a program crash. This issue has been addressed in with the patch v9.1.0707. All users are advised to upgrade.

Description: In the Linux kernel, the following vulnerability has been resolved:thunderbolt: Mark XDomain as unplugged when router is removedI noticed that when we do discrete host router NVM upgrade and it getshot-removed from the PCIe side as a result of NVM firmware authentication,if there is another host connected with enabled paths we hang in tearingthem down. This is due to fact that the Thunderbolt networking driveralso tries to cleanup the paths and ends up blocking intb_disconnect_xdomain_paths() waiting for the domain lock.However, at this point we already cleaned the paths in tb_stop() sothere is really no need for tb_disconnect_xdomain_paths() to do thatanymore. Furthermore it already checks if the XDomain is unplugged andbails out early so take advantage of that and mark the XDomain asunplugged when we remove the parent router.

That explains why there is no backref item for thatbytenr and why btrfs check is not reporting anything wrong.But this also shows another problem, as btrfs will do all the orphansubvolume cleanup at a read-write mount.So half-dropped subvolume should not exist after an RW mount, andbalance itself is also exclusive to subvolume cleanup, meaning weshouldn't hit a subvolume half-dropped during relocation.The root cause is, there is no orphan item for this subvolume.In fact there are 5 subvolumes from around 2021 that have the sameproblem.It looks like the original report has some older kernels running, andcaused those zombie subvolumes.Thankfully upstream commit 8d488a8c7ba2 ("btrfs: fix subvolume/snapshotdeletion not triggered on mount") has long fixed the bug.[ENHANCEMENT]For repairing such old fs, btrfs-progs will be enhanced.Considering how delayed the problem will show up (at run delayed reftime) and at that time we have to abort transaction already, it is toolate.Instead here we reject any half-dropped subvolume for reloc tree at theearliest time, preventing confusion and extra time wasted on debuggingsimilar bugs.

Thus, it is trying to acquire frag_sem semaphoreof the same file of which it already holds the semaphore obtained inflush_write_buffer(), leading to acquiring the semaphore in a nested mannerand a possibility of recursive locking.Fix this by modifying target_core_item_dbroot_store() to use kern_path()instead of filp_open() to avoid opening the file using filesystem-specificfunction __configfs_open_file(), and further modifying it to make this fixcompatible.

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: avoid overflows in ip6_datagram_send_ctl()Yiming Qian reported : I believe I found a locally triggerable kernel bug in the IPv6 sendmsg ancillary-data path that can panic the kernel via `skb_under_panic()` (local DoS). The core issue is a mismatch between: - a 16-bit length accumulator (`struct ipv6_txoptions::opt_flen`, type `__u16`) and - a pointer to the *last* provided destination-options header (`opt->dst1opt`) when multiple `IPV6_DSTOPTS` control messages (cmsgs) are provided. - `include/net/ipv6.h`: - `struct ipv6_txoptions::opt_flen` is `__u16` (wrap possible). (lines 291-307, especially 298) - `net/ipv6/datagram.c:ip6_datagram_send_ctl()`: - Accepts repeated `IPV6_DSTOPTS` and accumulates into `opt_flen` without rejecting duplicates. (lines 909-933) - `net/ipv6/ip6_output.c:__ip6_append_data()`: - Uses `opt->opt_flen + opt->opt_nflen` to compute header sizes/headroom decisions. (lines 1448-1466, especially 1463-1465) - `net/ipv6/ip6_output.c:__ip6_make_skb()`: - Calls `ipv6_push_frag_opts()` if `opt->opt_flen` is non-zero. (lines 1930-1934) - `net/ipv6/exthdrs.c:ipv6_push_frag_opts()` / `ipv6_push_exthdr()`: - Push size comes from `ipv6_optlen(opt->dst1opt)` (based on the pointed-to header). (lines 1179-1185 and 1206-1211) 1. `opt_flen` is a 16-bit accumulator: - `include/net/ipv6.h:298` defines `__u16 opt_flen; /* after fragment hdr */`. 2. `ip6_datagram_send_ctl()` accepts *repeated* `IPV6_DSTOPTS` cmsgs and increments `opt_flen` each time: - In `net/ipv6/datagram.c:909-933`, for `IPV6_DSTOPTS`: - It computes `len = ((hdr->hdrlen + 1) << 3);` - It checks `CAP_NET_RAW` using `ns_capable(net->user_ns, CAP_NET_RAW)`. (line 922) - Then it does: - `opt->opt_flen += len;` (line 927) - `opt->dst1opt = hdr;` (line 928) There is no duplicate rejection here (unlike the legacy `IPV6_2292DSTOPTS` path which rejects duplicates at `net/ipv6/datagram.c:901-904`). If enough large `IPV6_DSTOPTS` cmsgs are provided, `opt_flen` wraps while `dst1opt` still points to a large (2048-byte) destination-options header. In the attached PoC (`poc.c`): - 32 cmsgs with `hdrlen=255` => `len = (255+1)*8 = 2048` - 1 cmsg with `hdrlen=0` => `len = 8` - Total increment: `32*2048 + 8 = 65544`, so `(__u16)opt_flen == 8` - The last cmsg is 2048 bytes, so `dst1opt` points to a 2048-byte header. 3. The transmit path sizes headers using the wrapped `opt_flen`:- In `net/ipv6/ip6_output.c:1463-1465`: - `headersize = sizeof(struct ipv6hdr) + (opt ? opt->opt_flen + opt->opt_nflen : 0) + ...;` With wrapped `opt_flen`, `headersize`/headroom decisions underestimate what will be pushed later. 4. When building the final skb, the actual push length comes from `dst1opt` and is not limited by wrapped `opt_flen`: - In `net/ipv6/ip6_output.c:1930-1934`: - `if (opt->opt_flen) proto = ipv6_push_frag_opts(skb, opt, proto);` - In `net/ipv6/exthdrs.c:1206-1211`, `ipv6_push_frag_opts()` pushes `dst1opt` via `ipv6_push_exthdr()`. - In `net/ipv6/exthdrs.c:1179-1184`, `ipv6_push_exthdr()` does: - `skb_push(skb, ipv6_optlen(opt));` - `memcpy(h, opt, ipv6_optlen(opt));` With insufficient headroom, `skb_push()` underflows and triggers `skb_under_panic()` -> `BUG()`: - `net/core/skbuff.c:2669-2675` (`skb_push()` calls `skb_under_panic()`) - `net/core/skbuff.c:207-214` (`skb_panic()` ends in `BUG()`) - The `IPV6_DSTOPTS` cmsg path requires `CAP_NET_RAW` in the target netns user namespace (`ns_capable(net->user_ns, CAP_NET_RAW)`). - Root (or any task with `CAP_NET_RAW`) can trigger this without user namespaces. - An unprivileged `uid=1000` user can trigger this if unprivileged user namespaces are enabled and it can create a userns+netns to obtain namespaced `CAP_NET_RAW` (the attached PoC does this). - Local denial of service: kernel BUG/panic (system crash). ----truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ibmvfc: Fix OOB access in ibmvfc_discover_targets_done()A malicious or compromised VIO server can return a num_written value in thediscover targets MAD response that exceeds max_targets. This value isstored directly in vhost->num_targets without validation, and is then usedas the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], whichis only allocated for max_targets entries. Indices at or beyond max_targetsaccess kernel memory outside the DMA-coherent allocation. Theout-of-bounds data is subsequently embedded in Implicit Logout and PLOGIMADs that are sent back to the VIO server, leaking kernel memory.Fix by clamping num_written to max_targets before storing it.

Description: In the Linux kernel, the following vulnerability has been resolved:seg6: separate dst_cache for input and output paths in seg6 lwtunnelThe seg6 lwtunnel uses a single dst_cache per encap route, sharedbetween seg6_input_core() and seg6_output_core(). These two pathscan perform the post-encap SID lookup in different routing contexts(e.g., ip rules matching on the ingress interface, or VRF tableseparation). Whichever path runs first populates the cache, and theother reuses it blindly, bypassing its own lookup.Fix this by splitting the cache into cache_input and cache_output,so each path maintains its own cached dst independently.

Description: Rubygems.org is the Ruby community's gem hosting service. A Gem publisher can cause a Remote DoS when publishing a Gem. This is due to how Ruby reads the Manifest of Gem files when using Gem::Specification.from_yaml. from_yaml makes use of SafeYAML.load which allows YAML aliases inside the YAML-based metadata of a gem. YAML aliases allow for Denial of Service attacks with so-called `YAML-bombs` (comparable to Billion laughs attacks). This was patched. There is is no action required by users. This issue is also tracked as GHSL-2024-001 and was discovered by the GitHub security lab.

Description: In the Linux kernel, the following vulnerability has been resolved:nfc: pn533: Add poll mod list filling checkIn case of im_protocols value is 1 and tm_protocols value is 0 thiscombination successfully passes the check'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().But then after pn533_poll_create_mod_list() call in pn533_start_poll()poll mod list will remain empty and dev->poll_mod_count will remain 0which lead to division by zero.Normally no im protocol has value 1 in the mask, so this combination isnot expected by driver. But these protocol values actually come fromuserspace via Netlink interface (NFC_CMD_START_POLL operation). So abroken or malicious program may pass a message containing a "bad"combination of protocol parameter values so that dev->poll_mod_countis not incremented inside pn533_poll_create_mod_list(), thus leadingto division by zero.Call trace looks like:nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll()Add poll mod list filling check.Found by Linux Verification Center (linuxtesting.org) with SVACE.

Description: urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source.

Description: When switching to other buffers using the :all command and visual mode still being active, this may cause a heap-buffer overflow, because Vim does not properly end visual mode and therefore may try to access beyond the end of a line in a buffer. In Patch 9.1.1003 Vim will correctly reset the visual mode before opening other windows and buffers and therefore fix this bug. In addition it does verify that it won't try to access a position if the position is greater than the corresponding buffer line. Impact is medium since the user must have switched on visual mode when executing the :all ex command. The Vim project would like to thank github user gandalf4a for reporting this issue. The issue has been fixed as of Vim patch v9.1.1003

In silent Ex mode (-s -e), Vim typically doesn't show a screen and just operates silently in batch mode. However, it is still possible to trigger the function that handles the scrolling of a gui version of Vim by feeding some binary characters to Vim.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock between quota disable and qgroup rescan workerQuota disable ioctl starts a transaction before waiting for the qgrouprescan worker completes. However, this wait can be infinite and resultsin deadlock because of circular dependency among the quota disableioctl, the qgroup rescan worker and the other task with transaction suchas block group relocation task.The deadlock happens with the steps following:1) Task A calls ioctl to disable quota. It starts a transaction and waits for qgroup rescan worker completes.2) Task B such as block group relocation task starts a transaction and joins to the transaction that task A started. Then task B commits to the transaction. In this commit, task B waits for a commit by task A.3) Task C as the qgroup rescan worker starts its job and starts a transaction. In this transaction start, task C waits for completion of the transaction that task A started and task B committed.This deadlock was found with fstests test case btrfs/115 and a zonednull_blk device. The test case enables and disables quota, and theblock group reclaim was triggered during the quota disable by chance.The deadlock was also observed by running quota enable and disable inparallel with 'btrfs balance' command on regular null_blk devices.An example report of the deadlock: [372.469894] INFO: task kworker/u16:6:103 blocked for more than 122 seconds.

Description: Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in Vim's tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar archives. Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on. Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1552 contains a patch for the vulnerability.

Description: In the Linux kernel, the following vulnerability has been resolved:net: nfc: fix deadlock between nfc_unregister_device and rfkill_fop_writeA deadlock can occur between nfc_unregister_device() and rfkill_fop_write()due to lock ordering inversion between device_lock and rfkill_global_mutex.The problematic lock order is:Thread A (rfkill_fop_write): rfkill_fop_write() mutex_lock(&rfkill_global_mutex) rfkill_set_block() nfc_rfkill_set_block() nfc_dev_down() device_lock(&dev->dev) <- waits for device_lockThread B (nfc_unregister_device): nfc_unregister_device() device_lock(&dev->dev) rfkill_unregister() mutex_lock(&rfkill_global_mutex) <- waits for rfkill_global_mutexThis creates a classic ABBA deadlock scenario.Fix this by moving rfkill_unregister() and rfkill_destroy() outside thedevice_lock critical section. Store the rfkill pointer in a local variablebefore releasing the lock, then call rfkill_unregister() after releasingdevice_lock.This change is safe because rfkill_fop_write() holds rfkill_global_mutexwhile calling the rfkill callbacks, and rfkill_unregister() also acquiresrfkill_global_mutex before cleanup. Therefore, rfkill_unregister() willwait for any ongoing callback to complete before proceeding, anddevice_del() is only called after rfkill_unregister() returns, preventingany use-after-free.The similar lock ordering in nfc_register_device() (device_lock ->rfkill_global_mutex via rfkill_register) is safe because duringregistration the device is not yet in rfkill_list, so no concurrentrfkill operations can occur on this device.

Description: A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: don't walk off the end of a directory data blockThis adds sanity checks for xfs_dir2_data_unused and xfs_dir2_data_entryto make sure don't stray beyond valid memory region. Before patching, theloop simply checks that the start offset of the dup and dep is within therange. So in a crafted image, if last entry is xfs_dir2_data_unused, wecan change dup->length to dup->length-1 and leave 1 byte of space. In thenext traversal, this space will be considered as dup or dep. We mayencounter an out of bound read when accessing the fixed members.In the patch, we make sure that the remaining bytes large enough to holdan unused entry before accessing xfs_dir2_data_unused andxfs_dir2_data_unused is XFS_DIR2_DATA_ALIGN byte aligned. We also makesure that the remaining bytes large enough to hold a dirent with asingle-byte name before accessing xfs_dir2_data_entry.

Description: The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in argument list handling. When adding a new file to the argument list, this triggers `Buf*` autocommands. If in such an autocommand the buffer that was just opened is closed (including the window where it is shown), this causes the window structure to be freed which contains a reference to the argument list that we are actually modifying. Once the autocommands are completed, the references to the window and argument list are no longer valid and as such cause an use-after-free. Impact is low since the user must either intentionally add some unusual autocommands that wipe a buffer during creation (either manually or by sourcing a malicious plugin), but it will crash Vim. The issue has been fixed as of Vim patch v9.1.0678.

Description: An issue was discovered in elf_link_input_bfd in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in elf_link_input_bfd when used for finding STT_TLS symbols without any TLS section. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.

Description: In the Linux kernel, the following vulnerability has been resolved:iommu/vt-d: Fix PCI device refcount leak in dmar_dev_scope_init()for_each_pci_dev() is implemented by pci_get_device(). The comment ofpci_get_device() says that it will increase the reference count for thereturned pci_dev and also decrease the reference count for the inputpci_dev @from if it is not NULL.If we break for_each_pci_dev() loop with pdev not NULL, we need to callpci_dev_put() to decrease the reference count. Add the missingpci_dev_put() for the error path to avoid reference count leak.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: Fail COMEDI_INSNLIST ioctl if n_insns is too largeThe handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer tohold the array of `struct comedi_insn`, getting the length from the`n_insns` member of the `struct comedi_insnlist` supplied by the user.The allocation will fail with a WARNING and a stack dump if it is toolarge.Avoid that by failing with an `-EINVAL` error if the supplied `n_insns`value is unreasonable.Define the limit on the `n_insns` value in the `MAX_INSNS` macro. Setthis to the same value as `MAX_SAMPLES` (65536), which is the maximumallowed sum of the values of the member `n` in the array of `structcomedi_insn`, and sensible comedi instructions will have an `n` of atleast 1.

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: qat - fix DMA transfer directionWhen CONFIG_DMA_API_DEBUG is selected, while running the crypto selftest on the QAT crypto algorithms, the function add_dma_entry() reportsa warning similar to the one below, saying that overlapping mappingsare not supported. This occurs in tests where the input and the outputscatter list point to the same buffers (i.e. two different scatter listswhich point to the same chunks of memory).The logic that implements the mapping uses the flag DMA_BIDIRECTIONALfor both the input and the output scatter lists which leads tooverlapped write mappings. These are not supported by the DMA layer.Fix by specifying the correct DMA transfer directions when mappingbuffers. For in-place operations where the input scatter listmatches the output scatter list, buffers are mapped once withDMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flagDMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE.Overlapping a read mapping with a write mapping is a valid case indma-coherent devices like QAT.The function that frees and unmaps the buffers, qat_alg_free_bufl()has been changed accordingly to the changes to the mapping function.

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Fix data races in unix_release_sock/unix_stream_sendmsgA data-race condition has been identified in af_unix. In one data path,the write function unix_release_sock() atomically writes tosk->sk_shutdown using WRITE_ONCE. However, on the reader side,unix_stream_sendmsg() does not read it atomically.

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: clear PARENT_WATCHED flags lazilyIn some setups directories can have many (usually negative) dentries.Hence __fsnotify_update_child_dentry_flags() function can take asignificant amount of time. Since the bulk of this function happensunder inode->i_lock this causes a significant contention on the lockwhen we remove the watch from the directory as the__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()races with __fsnotify_update_child_dentry_flags() calls from__fsnotify_parent() happening on children. This can lead upto softlockupreports reported by users.Fix the problem by calling fsnotify_update_children_dentry_flags() toset PARENT_WATCHED flags only when parent starts watching children.When parent stops watching children, clear false positive PARENT_WATCHEDflags lazily in __fsnotify_parent() for each accessed child.

Description: In the Linux kernel, the following vulnerability has been resolved:net/ipv6: release expired exception dst cached in socketDst objects get leaked in ip6_negative_advice() when this function isexecuted for an expired IPv6 route located in the exception table. Thereare several conditions that must be fulfilled for the leak to occur:* an ICMPv6 packet indicating a change of the MTU for the path is received, resulting in an exception dst being created* a TCP connection that uses the exception dst for routing packets must start timing out so that TCP begins retransmissions* after the exception dst expires, the FIB6 garbage collector must not run before TCP executes ip6_negative_advice() for the expired exception dstWhen TCP executes ip6_negative_advice() for an exception dst that hasexpired and if no other socket holds a reference to the exception dst, therefcount of the exception dst is 2, which corresponds to the incrementmade by dst_init() and the increment made by the TCP socket for which theconnection is timing out. The refcount made by the socket is neverreleased. The refcount of the dst is decremented in sk_dst_reset() butthat decrement is counteracted by a dst_hold() intentionally placed justbefore the sk_dst_reset() in ip6_negative_advice(). Afterip6_negative_advice() has finished, there is no other object tied to thedst. The socket lost its reference stored in sk_dst_cache and the dst isno longer in the exception table. The exception dst becomes a leakedobject.As a result of this dst leak, an unbalanced refcount is reported for theloopback device of a net namespace being destroyed under kernels that donot contain e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"):unregister_netdevice: waiting for lo to become free. Usage count = 2Fix the dst leak by removing the dst_hold() in ip6_negative_advice(). Thepatch that introduced the dst_hold() in ip6_negative_advice() was92f1655aa2b22 ("net: fix __dst_negative_advice() race"). But 92f1655aa2b22merely refactored the code with regards to the dst refcount so the issuewas present even before 92f1655aa2b22. The bug was introduced in54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actuallyexpired.") where the expired cached route is deleted and the sk_dst_cachemember of the socket is set to NULL by calling dst_negative_advice() butthe refcount belonging to the socket is left unbalanced.The IPv4 version - ipv4_negative_advice() - is not affected by this bug.When the TCP connection times out ipv4_negative_advice() merely resets thesk_dst_cache of the socket while decrementing the refcount of theexception dst.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/kmemleak: avoid soft lockup in __kmemleak_do_cleanup()A soft lockup warning was observed on a relative small system x86-64system with 16 GB of memory when running a debug kernel with kmemleakenabled. watchdog: BUG: soft lockup - CPU#8 stuck for 33s! [kworker/8:1:134]The test system was running a workload with hot unplug happening inparallel. Then kemleak decided to disable itself due to its inability toallocate more kmemleak objects. The debug kernel has itsCONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE set to 40,000.The soft lockup happened in kmemleak_do_cleanup() when the existingkmemleak objects were being removed and deleted one-by-one in a loop via aworkqueue. In this particular case, there are at least 40,000 objectsthat need to be processed and given the slowness of a debug kernel and thefact that a raw_spinlock has to be acquired and released in__delete_object(), it could take a while to properly handle all theseobjects.As kmemleak has been disabled in this case, the object removal anddeletion process can be further optimized as locking isn't really needed. However, it is probably not worth the effort to optimize for such an edgecase that should rarely happen. So the simple solution is to callcond_resched() at periodic interval in the iteration loop to avoid softlockup.

It reportswarning messages in function __blkdev_issue_discard when mkfs.xfslike this:[ 4616.022599] ------------[ cut here ]------------[ 4616.027779] WARNING: CPU: 4 PID: 99634 at block/blk-lib.c:50 __blkdev_issue_discard+0x16a/0x1a0[ 4616.140663] RIP: 0010:__blkdev_issue_discard+0x16a/0x1a0[ 4616.146601] Code: 24 4c 89 20 31 c0 e9 fe fe ff ff c1 e8 09 8d 48 ff 4c 89 f0 4c 09 e8 48 85 c1 0f 84 55 ff ff ff b8 ea ff ff ff e9 df fe ff ff <0f> 0b 48 8d 74 24 08 e8 ea d6 00 00 48 c7 c6 20 1e 89 ab 48 c7 c7[ 4616.167567] RSP: 0018:ffffaab88cbffca8 EFLAGS: 00010246[ 4616.173406] RAX: ffff9ba1f9e44678 RBX: 0000000000000000 RCX: ffff9ba1c9792080[ 4616.181376] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff9ba1c9792080[ 4616.189345] RBP: 0000000000000cc0 R08: ffffaab88cbffd10 R09: 0000000000000000[ 4616.197317] R10: 0000000000000012 R11: 0000000000000000 R12: 0000000000000000[ 4616.205288] R13: 0000000000400000 R14: 0000000000000cc0 R15: ffff9ba1c9792080[ 4616.213259] FS: 00007f9a5534e980(0000) GS:ffff9ba1b7c80000(0000) knlGS:0000000000000000[ 4616.222298] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 4616.228719] CR2: 000055a390a4c518 CR3: 0000000123e40006 CR4: 00000000001706e0[ 4616.236689] Call Trace:[ 4616.239428] blkdev_issue_discard+0x52/0xb0[ 4616.244108] blkdev_common_ioctl+0x43c/0xa00[ 4616.248883] blkdev_ioctl+0x116/0x280[ 4616.252977] __x64_sys_ioctl+0x8a/0xc0[ 4616.257163] do_syscall_64+0x5c/0x90[ 4616.261164] ? handle_mm_fault+0xc5/0x2a0[ 4616.265652] ? do_user_addr_fault+0x1d8/0x690[ 4616.270527] ? do_syscall_64+0x69/0x90[ 4616.274717] ? exc_page_fault+0x62/0x150[ 4616.279097] entry_SYSCALL_64_after_hwframe+0x63/0xcd[ 4616.284748] RIP: 0033:0x7f9a55398c6b

Description: In the Linux kernel, the following vulnerability has been resolved:start_kernel: Add __no_stack_protector function attributeBack during the discussion ofcommit a9a3ed1eff36 ("x86: Fix early boot crash on gcc-10, third try")we discussed the need for a function attribute to control the omissionof stack protectors on a per-function basis; at the time Clang hadsupport for no_stack_protector but GCC did not. This was fixed ingcc-11. Now that the function attribute is available, let's start usingit.Callers of boot_init_stack_canary need to use this function attributeunless they're compiled with -fno-stack-protector, otherwise the canarystored in the stack slot of the caller will differ upon the call toboot_init_stack_canary. This will lead to a call to __stack_chk_fail()then panic.

Description: In the Linux kernel, the following vulnerability has been resolved:qed: allow sleep in qed_mcp_trace_dump()By default, qed_mcp_cmd_and_union() delays 10us at a time in a loopthat can run 500K times, so calls to qed_mcp_nvm_rd_cmd()may block the current thread for over 5s.We observed thread scheduling delays over 700ms in production,with stacktraces pointing to this code as the culprit.qed_mcp_trace_dump() is called from ethtool, so sleeping is permitted.It already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd().Add a "can sleep" parameter to qed_find_nvram_image() andqed_nvram_read() so they can sleep during qed_mcp_trace_dump().qed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(),called only by qed_mcp_trace_dump(), allow these functions to sleep.I can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep,so keep b_can_sleep set to false when it calls these functions.An example stacktrace from a custom warning we added to the kernelshowing a thread that has not scheduled despite long needing resched:[ 2745.362925,17] ------------[ cut here ]------------[ 2745.362941,17] WARNING: CPU: 23 PID: 5640 at arch/x86/kernel/irq.c:233 do_IRQ+0x15e/0x1a0()[ 2745.362946,17] Thread not rescheduled for 744 ms after irq 99[ 2745.362956,17] Modules linked in: ...[ 2745.363339,17] CPU: 23 PID: 5640 Comm: lldpd Tainted: P O 4.4.182+ #202104120910+6d1da174272d.61x[ 2745.363343,17] Hardware name: FOXCONN MercuryB/Quicksilver Controller, BIOS H11P1N09 07/08/2020[ 2745.363346,17] 0000000000000000 ffff885ec07c3ed8 ffffffff8131eb2f ffff885ec07c3f20[ 2745.363358,17] ffffffff81d14f64 ffff885ec07c3f10 ffffffff81072ac2 ffff88be98ed0000[ 2745.363369,17] 0000000000000063 0000000000000174 0000000000000074 0000000000000000[ 2745.363379,17] Call Trace:[ 2745.363382,17] [] dump_stack+0x8e/0xcf[ 2745.363393,17] [] warn_slowpath_common+0x82/0xc0[ 2745.363398,17] [] warn_slowpath_fmt+0x4c/0x50[ 2745.363404,17] [] ? rcu_irq_exit+0xae/0xc0[ 2745.363408,17] [] do_IRQ+0x15e/0x1a0[ 2745.363413,17] [] common_interrupt+0x89/0x89[ 2745.363416,17] [] ? delay_tsc+0x24/0x50[ 2745.363425,17] [] __udelay+0x34/0x40[ 2745.363457,17] [] qed_mcp_cmd_and_union+0x36f/0x7d0 [qed][ 2745.363473,17] [] qed_mcp_nvm_rd_cmd+0x4d/0x90 [qed][ 2745.363490,17] [] qed_mcp_trace_dump+0x4a7/0x630 [qed][ 2745.363504,17] [] ? qed_fw_asserts_dump+0x1d6/0x1f0 [qed][ 2745.363520,17] [] qed_dbg_mcp_trace_get_dump_buf_size+0x37/0x80 [qed][ 2745.363536,17] [] qed_dbg_feature_size+0x61/0xa0 [qed][ 2745.363551,17] [] qed_dbg_all_data_size+0x247/0x260 [qed][ 2745.363560,17] [] qede_get_regs_len+0x30/0x40 [qede][ 2745.363566,17] [] ethtool_get_drvinfo+0xe3/0x190[ 2745.363570,17] [] dev_ethtool+0x1362/0x2140[ 2745.363575,17] [] ? finish_task_switch+0x76/0x260[ 2745.363580,17] [] ? __schedule+0x3c6/0x9d0[ 2745.363585,17] [] ? hrtimer_start_range_ns+0x1d0/0x370[ 2745.363589,17] [] ? dev_get_by_name_rcu+0x6b/0x90[ 2745.363594,17] [] dev_ioctl+0xe8/0x710[ 2745.363599,17] [] sock_do_ioctl+0x48/0x60[ 2745.363603,17] [] sock_ioctl+0x1c7/0x280[ 2745.363608,17] [] ? seccomp_phase1+0x83/0x220[ 2745.363612,17] [] do_vfs_ioctl+0x2b3/0x4e0[ 2745.363616,17] [] SyS_ioctl+0x41/0x70[ 2745.363619,17] [] entry_SYSCALL_64_fastpath+0x1e/0x79[ 2745.363622,17] ---[ end trace f6954aa440266421 ]---

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: drop unnecessary user-triggerable WARN_ONCE in verifierl logIt's trivial for user to trigger "verifier log line truncated" warning,as verifier has a fixed-sized buffer of 1024 bytes (as of now), and there are atleast two pieces of user-provided information that can be output throughthis buffer, and both can be arbitrarily sized by user: - BTF names; - BTF.ext source code lines strings.Verifier log buffer should be properly sized for typical verifier stateoutput. But it's sort-of expected that this buffer won't be long enoughin some circumstances. So let's drop the check. In any case code willwork correctly, at worst truncating a part of a single line output.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: remove BUG_ON()'s in add_new_free_space()At add_new_free_space() we have these BUG_ON()'s that are there to dealwith any failure to add free space to the in memory free space cache.Such failures are mostly -ENOMEM that should be very rare. However there'sno need to have these BUG_ON()'s, we can just return any error to thecaller and all callers and their upper call chain are already dealing witherrors.So just make add_new_free_space() return any errors, while removing theBUG_ON()'s, and returning the total amount of added free space to anoptional u64 pointer argument.

Description: In the Linux kernel, the following vulnerability has been resolved:usb: dwc3: Remove WARN_ON for device endpoint command timeoutsThis commit addresses a rarely observed endpoint command timeoutwhich causes kernel panic due to warn when 'panic_on_warn' is enabledand unnecessary call trace prints when 'panic_on_warn' is disabled.It is seen during fast software-controlled connect/disconnect testcases.The following is one such endpoint command timeout that we observed:1. Connect =======->dwc3_thread_interrupt ->dwc3_ep0_interrupt ->configfs_composite_setup ->composite_setup ->usb_ep_queue ->dwc3_gadget_ep0_queue ->__dwc3_gadget_ep0_queue ->__dwc3_ep0_do_control_data ->dwc3_send_gadget_ep_cmd2. Disconnect ==========->dwc3_thread_interrupt ->dwc3_gadget_disconnect_interrupt ->dwc3_ep0_reset_state ->dwc3_ep0_end_control_data ->dwc3_send_gadget_ep_cmdIn the issue scenario, in Exynos platforms, we observed that controltransfers for the previous connect have not yet been completed and endtransfer command sent as a part of the disconnect sequence andprocessing of USB_ENDPOINT_HALT feature request from the host timeout.This maybe an expected scenario since the controller is processing EPcommands sent as a part of the previous connect. It maybe better toremove WARN_ON in all places where device endpoint commands are sent toavoid unnecessary kernel panic due to warn.

Description: In the Linux kernel, the following vulnerability has been resolved:ixgbevf: fix mailbox API compatibility by negotiating supported featuresThere was backward compatibility in the terms of mailbox API. Variousdrivers from various OSes supporting 10G adapters from Intel portfoliocould easily negotiate mailbox API.This convention has been broken since introducing API 1.4.Commit 0062e7cc955e ("ixgbevf: add VF IPsec offload code") added supportfor IPSec which is specific only for the kernel ixgbe driver. None of therest of the Intel 10G PF/VF drivers supports it. And actually lack ofsupport was not included in the IPSec implementation - there were no suchcode paths. No possibility to negotiate support for the feature wasintroduced along with introduction of the feature itself.Commit 339f28964147 ("ixgbevf: Add support for new mailbox communicationbetween PF and VF") increasing API version to 1.5 did the same - itintroduced code supported specifically by the PF ESX driver. It altered APIversion for the VF driver in the same time not touching the versiondefined for the PF ixgbe driver. It led to additional discrepancies,as the code provided within API 1.6 cannot be supported for Linux ixgbedriver as it causes crashes.The issue was noticed some time ago and mitigated by Jake within the commitd0725312adf5 ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").As a result we have regression for IPsec support and after increasing APIto version 1.6 ixgbevf driver stopped to support ESX MBX.To fix this mess add new mailbox op asking PF driver about supportedfeatures. Basing on a response determine whether to set support for IPSecand ESX-specific enhanced mailbox.New mailbox op, for compatibility purposes, must be added within new APIrevision, as API version of OOT PF & VF drivers is already increased to1.6 and doesn't incorporate features negotiate op.Features negotiation mechanism gives possibility to be extended with newfeatures when needed in the future.
