CVE-2023-34049 Severity: Important CVSS3 score: 8.4

Description: The Salt-SSH pre-flight option copies the script to the target at a predictable path, which allows an attacker to force Salt-SSH to run their script. If an attacker has access to the target VM and knows the path to the pre-flight script before it runs they can ensure Salt-SSH runs their script with the privileges of the user running Salt-SSH. Do not make the copy path on the target predictable and ensure we check return codes of the scp command if the copy fails.

CVE-2020-14664 Severity: Important CVSS3 score: 8.3

Description: Vulnerability in the Java SE product of Oracle Java SE (component: JavaFX). The supported version that is affected is Java SE: 8u251. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator).

CVE-2024-47220 Severity: Important CVSS3 score: 8.2

Description: An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby. It allows HTTP request smuggling by providing both a Content-Length header and a Transfer-Encoding header, e.g., "GET /admin HTTP/1.1\r\n" inside of a "POST /user HTTP/1.1\r\n" request.

CVE-2026-33186 Severity: Important CVSS3 score: 8.1

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.

CVE-2022-48991 Severity: Important CVSS3 score: 7.8

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.

Description: In the Linux kernel, the following vulnerability has been resolved:net: tls: handle backlogging of crypto requestsSince we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on ourrequests to the crypto API, crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in valid situations. 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. The handling is identical.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOTIn qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumedto be either root or ingress. This assumption is bogus since it's validto create egress qdiscs with major handle ffff:Budimir Markovic found that for qdiscs like DRR that maintain an activeclass list, it will cause a UAF with a dangling class pointer.In 066a3b5b2346, the concern was to avoid iterating over the ingressqdisc since its parent is itself. The proper fix is to stop when parentTC_H_ROOT is reached because the only way to retrieve ingress is when ahierarchy which does not contain a ffff: major handle call intoqdisc_lookup with TC_H_MAJ(TC_H_ROOT).In the scenario where major ffff: is an egress qdisc in any of the treelevels, the updates will also propagate to TC_H_ROOT, which then theiteration must stop. net/sched/sch_api.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

When the network namespace is deleted, the net structureaccessed by tcp's timer handler function causes problems.To fix this problem, let's hold netns refcnt for the tcp kernel socket asdone in other modules. This is an ugly hack which can easily be backportedto earlier kernels. A proper fix which cleans up the interfaces willfollow, but may not be so easy to backport.

CVE-2024-53214 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:vfio/pci: Properly hide first-in-list PCIe extended capabilityThere are cases where a PCIe extended capability should be hidden fromthe user. For example, an unknown capability (i.e., capability with IDgreater than PCI_EXT_CAP_ID_MAX) or a capability that is intentionallychosen to be hidden from the user.Hiding a capability is done by virtualizing and modifying the 'NextCapability Offset' field of the previous capability so it points to thecapability after the one that should be hidden.The special case where the first capability in the list should be hiddenis handled differently because there is no previous capability that canbe modified. In this case, the capability ID and version are zeroedwhile leaving the next pointer intact. This hides the capability andleaves an anchor for the rest of the capability list.However, today, hiding the first capability in the list is not doneproperly if the capability is unknown, as structvfio_pci_core_device->pci_config_map is set to the capability ID duringinitialization but the capability ID is not properly checked later whenused in vfio_config_do_rw(). This leads to the following warning [1] andto an out-of-bounds access to ecap_perms array.Fix it by checking cap_id in vfio_config_do_rw(), and if it is greaterthan PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for directread only access instead of the ecap_perms array.Note that this is safe since the above is the only case where cap_id canexceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, whichare already checked before).[1]WARNING: CPU: 118 PID: 5329 at drivers/vfio/pci/vfio_pci_config.c:1900 vfio_pci_config_rw+0x395/0x430 [vfio_pci_core]CPU: 118 UID: 0 PID: 5329 Comm: simx-qemu-syste Not tainted 6.12.0+ #1(snip)Call Trace: ? show_regs+0x69/0x80 ? __warn+0x8d/0x140 ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core] ? report_bug+0x18f/0x1a0 ? handle_bug+0x63/0xa0 ? exc_invalid_op+0x19/0x70 ? asm_exc_invalid_op+0x1b/0x20 ? vfio_pci_config_rw+0x395/0x430 [vfio_pci_core] ? vfio_pci_config_rw+0x244/0x430 [vfio_pci_core] vfio_pci_rw+0x101/0x1b0 [vfio_pci_core] vfio_pci_core_read+0x1d/0x30 [vfio_pci_core] vfio_device_fops_read+0x27/0x40 [vfio] vfs_read+0xbd/0x340 ? vfio_device_fops_unl_ioctl+0xbb/0x740 [vfio] ? __rseq_handle_notify_resume+0xa4/0x4b0 __x64_sys_pread64+0x96/0xc0 x64_sys_call+0x1c3d/0x20d0 do_syscall_64+0x4d/0x120 entry_SYSCALL_64_after_hwframe+0x76/0x7e

TBF is out of tokens so it schedules itself for later.* the second packet is sent and TBF tries to queues it to SFQ. qdisc qlen is now 2 and because the SFQ limit is 1 the packet is dropped by SFQ. At this point qlen is 1, and all of the SFQ slots are empty, however q->tail is not NULL.At this point, assuming no more packets are queued, when sch_dequeueruns again it will decrement the qlen for the current empty slotcausing an underflow and the subsequent out of bounds access.

CVE-2025-21702 Severity: Important CVSS3 score: 7.8

Description: In the Linux kernel, the following vulnerability has been resolved:pfifo_tail_enqueue: Drop new packet when sch->limit == 0Expected behaviour:In case we reach scheduler's limit, pfifo_tail_enqueue() will drop apacket in scheduler's queue and decrease scheduler's qlen by one.Then, pfifo_tail_enqueue() enqueue new packet and increasescheduler's qlen by one. Finally, pfifo_tail_enqueue() return`NET_XMIT_CN` status code.Weird behaviour:In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on ascheduler that has no packet, the 'drop a packet' step will do nothing.This means the scheduler's qlen still has value equal 0.Then, we continue to enqueue new packet and increase scheduler's qlen byone. In summary, we can leverage pfifo_tail_enqueue() to increase qlen byone and return `NET_XMIT_CN` status code.The problem is:Let's say we have two qdiscs: Qdisc_A and Qdisc_B. - Qdisc_A's type must have '->graft()' function to create parent/child relationship. Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`. - Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`. - Qdisc_B is configured to have `sch->limit == 0`. - Qdisc_A is configured to route the enqueued's packet to Qdisc_B.Enqueue packet through Qdisc_A will lead to: - hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B) - Qdisc_B->q.qlen += 1 - pfifo_tail_enqueue() return `NET_XMIT_CN` - hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A.The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1.Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem.This violate the design where parent's qlen should equal to the sum of its childrens'qlen.Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

CVE-2021-3449 Severity: Important CVSS3 score: 7.5

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).

CVE-2021-43809 Severity: Important CVSS3 score: 7.3

Description: `Bundler` is a package for managing application dependencies in Ruby. In `bundler` versions before 2.2.33, when working with untrusted and apparently harmless `Gemfile`'s, it is not expected that they lead to execution of external code, unless that's explicit in the ruby code inside the `Gemfile` itself. However, if the `Gemfile` includes `gem` entries that use the `git` option with invalid, but seemingly harmless, values with a leading dash, this can be false. To handle dependencies that come from a Git repository instead of a registry, Bundler uses various commands, such as `git clone`. These commands are being constructed using user input (e.g. the repository URL). When building the commands, Bundler versions before 2.2.33 correctly avoid Command Injection vulnerabilities by passing an array of arguments instead of a command string. However, there is the possibility that a user input starts with a dash (`-`) and is therefore treated as an optional argument instead of a positional one. This can lead to Code Execution because some of the commands have options that can be leveraged to run arbitrary executables. Since this value comes from the `Gemfile` file, it can contain any character, including a leading dash.To exploit this vulnerability, an attacker has to craft a directory containing a `Gemfile` file that declares a dependency that is located in a Git repository. This dependency has to have a Git URL in the form of `-u./payload`. This URL will be used to construct a Git clone command but will be interpreted as the upload-pack argument. Then this directory needs to be shared with the victim, who then needs to run a command that evaluates the Gemfile, such as `bundle lock`, inside.This vulnerability can lead to Arbitrary Code Execution, which could potentially lead to the takeover of the system. However, the exploitability is very low, because it requires a lot of user interaction. Bundler 2.2.33 has patched this problem by inserting `--` as an argument before any positional arguments to those Git commands that were affected by this issue. Regardless of whether users can upgrade or not, they should review any untrustred `Gemfile`'s before running any `bundler` commands that may read them, since they can contain arbitrary ruby code.

However, the work decrements thecount too early before releasing the kernel socket,unblocking cleanup_net() and resulting in use-after-free.Let's move the decrement after releasing the socket incleanup_bearer().[0]:ref_tracker: net notrefcnt@000000009b3d1faf has 1/1 users at sk_alloc+0x438/0x608 inet_create+0x4c8/0xcb0 __sock_create+0x350/0x6b8 sock_create_kern+0x58/0x78 udp_sock_create4+0x68/0x398 udp_sock_create+0x88/0xc8 tipc_udp_enable+0x5e8/0x848 __tipc_nl_bearer_enable+0x84c/0xed8 tipc_nl_bearer_enable+0x38/0x60 genl_family_rcv_msg_doit+0x170/0x248 genl_rcv_msg+0x400/0x5b0 netlink_rcv_skb+0x1dc/0x398 genl_rcv+0x44/0x68 netlink_unicast+0x678/0x8b0 netlink_sendmsg+0x5e4/0x898 ____sys_sendmsg+0x500/0x830[1]:BUG: KMSAN: use-after-free in udp_hashslot include/net/udp.h:85 [inline]BUG: KMSAN: use-after-free in udp_lib_unhash+0x3b8/0x930 net/ipv4/udp.c:1979 udp_hashslot include/net/udp.h:85 [inline] udp_lib_unhash+0x3b8/0x930 net/ipv4/udp.c:1979 sk_common_release+0xaf/0x3f0 net/core/sock.c:3820 inet_release+0x1e0/0x260 net/ipv4/af_inet.c:437 inet6_release+0x6f/0xd0 net/ipv6/af_inet6.c:489 __sock_release net/socket.c:658 [inline] sock_release+0xa0/0x210 net/socket.c:686 cleanup_bearer+0x42d/0x4c0 net/tipc/udp_media.c:819 process_one_work kernel/workqueue.c:3229 [inline] process_scheduled_works+0xcaf/0x1c90 kernel/workqueue.c:3310 worker_thread+0xf6c/0x1510 kernel/workqueue.c:3391 kthread+0x531/0x6b0 kernel/kthread.c:389 ret_from_fork+0x60/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x11/0x20 arch/x86/entry/entry_64.S:244Uninit was created at: slab_free_hook mm/slub.c:2269 [inline] slab_free mm/slub.c:4580 [inline] kmem_cache_free+0x207/0xc40 mm/slub.c:4682 net_free net/core/net_namespace.c:454 [inline] cleanup_net+0x16f2/0x19d0 net/core/net_namespace.c:647 process_one_work kernel/workqueue.c:3229 [inline] process_scheduled_works+0xcaf/0x1c90 kernel/workqueue.c:3310 worker_thread+0xf6c/0x1510 kernel/workqueue.c:3391 kthread+0x531/0x6b0 kernel/kthread.c:389 ret_from_fork+0x60/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x11/0x20 arch/x86/entry/entry_64.S:244CPU: 0 UID: 0 PID: 54 Comm: kworker/0:2 Not tainted 6.12.0-rc1-00131-gf66ebf37d69c #7 91723d6f74857f70725e1583cba3cf4adc716cfaHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014Workqueue: events cleanup_bearer

CVE-2018-1000030 Severity: Important CVSS3 score: 7.0

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.

CVE-2024-45016 Severity: Important CVSS3 score: 7.0

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.

""" We are seeing a use-after-free from a bpf prog attached to trace_tcp_retransmit_synack.

CVE-2024-49940 Severity: Moderate CVSS3 score: 6.8

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. Add a check forthis case.

CVE-2024-56548 Severity: Important CVSS3 score: 6.7

Description: In the Linux kernel, the following vulnerability has been resolved:hfsplus: don't query the device logical block size multiple timesDevices block sizes may change. One of these cases is a loop device byusing ioctl LOOP_SET_BLOCK_SIZE.While this may cause other issues like IO being rejected, in the case ofhfsplus, it will allocate a block by using that size and potentially writeout-of-bounds when hfsplus_read_wrapper calls hfsplus_submit_bio and thelatter function reads a different io_size.Using a new min_io_size initally set to sb_min_blocksize works for thepurposes of the original fix, since it will be set to the max betweenHFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use themax between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is notinitialized.Tested by mounting an hfsplus filesystem with loop block sizes 512, 1024and 4096.The produced KASAN report before the fix looks like this:[ 419.944641] ==================================================================[ 419.945655] BUG: KASAN: slab-use-after-free in hfsplus_read_wrapper+0x659/0xa0a[ 419.946703] Read of size 2 at addr ffff88800721fc00 by task repro/10678[ 419.947612][ 419.947846] CPU: 0 UID: 0 PID: 10678 Comm: repro Not tainted 6.12.0-rc5-00008-gdf56e0f2f3ca #84[ 419.949007] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014[ 419.950035] Call Trace:[ 419.950384] [ 419.950676] dump_stack_lvl+0x57/0x78[ 419.951212] ? hfsplus_read_wrapper+0x659/0xa0a[ 419.951830] print_report+0x14c/0x49e[ 419.952361] ? __virt_addr_valid+0x267/0x278[ 419.952979] ? kmem_cache_debug_flags+0xc/0x1d[ 419.953561] ? hfsplus_read_wrapper+0x659/0xa0a[ 419.954231] kasan_report+0x89/0xb0[ 419.954748] ? hfsplus_read_wrapper+0x659/0xa0a[ 419.955367] hfsplus_read_wrapper+0x659/0xa0a[ 419.955948] ? __pfx_hfsplus_read_wrapper+0x10/0x10[ 419.956618] ? do_raw_spin_unlock+0x59/0x1a9[ 419.957214] ? _raw_spin_unlock+0x1a/0x2e[ 419.957772] hfsplus_fill_super+0x348/0x1590[ 419.958355] ? hlock_class+0x4c/0x109[ 419.958867] ? __pfx_hfsplus_fill_super+0x10/0x10[ 419.959499] ? __pfx_string+0x10/0x10[ 419.960006] ? lock_acquire+0x3e2/0x454[ 419.960532] ? bdev_name.constprop.0+0xce/0x243[ 419.961129] ? __pfx_bdev_name.constprop.0+0x10/0x10[ 419.961799] ? pointer+0x3f0/0x62f[ 419.962277] ? __pfx_pointer+0x10/0x10[ 419.962761] ? vsnprintf+0x6c4/0xfba[ 419.963178] ? __pfx_vsnprintf+0x10/0x10[ 419.963621] ? setup_bdev_super+0x376/0x3b3[ 419.964029] ? snprintf+0x9d/0xd2[ 419.964344] ? __pfx_snprintf+0x10/0x10[ 419.964675] ? lock_acquired+0x45c/0x5e9[ 419.965016] ? set_blocksize+0x139/0x1c1[ 419.965381] ? sb_set_blocksize+0x6d/0xae[ 419.965742] ? __pfx_hfsplus_fill_super+0x10/0x10[ 419.966179] mount_bdev+0x12f/0x1bf[ 419.966512] ? __pfx_mount_bdev+0x10/0x10[ 419.966886] ? vfs_parse_fs_string+0xce/0x111[ 419.967293] ? __pfx_vfs_parse_fs_string+0x10/0x10[ 419.967702] ? __pfx_hfsplus_mount+0x10/0x10[ 419.968073] legacy_get_tree+0x104/0x178[ 419.968414] vfs_get_tree+0x86/0x296[ 419.968751] path_mount+0xba3/0xd0b[ 419.969157] ? __pfx_path_mount+0x10/0x10[ 419.969594] ? kmem_cache_free+0x1e2/0x260[ 419.970311] do_mount+0x99/0xe0[ 419.970630] ? __pfx_do_mount+0x10/0x10[ 419.971008] __do_sys_mount+0x199/0x1c9[ 419.971397] do_syscall_64+0xd0/0x135[ 419.971761] entry_SYSCALL_64_after_hwframe+0x76/0x7e[ 419.972233] RIP: 0033:0x7c3cb812972e[ 419.972564] Code: 48 8b 0d f5 46 0d 00 f7 d8 64 89 01 48 83 c8 ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 49 89 ca b8 a5 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d c2 46 0d 00 f7 d8 64 89 01 48[ 419.974371] RSP: 002b:00007ffe30632548 EFLAGS: 00000286 ORIG_RAX: 00000000000000a5[ 419.975048] RAX: ffffffffffffffda RBX: 00007ffe306328d8 RCX: 00007c3cb812972e[ 419.975701] RDX: 0000000020000000 RSI: 0000000020000c80 RDI:---truncated---

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

CVE-2022-49006 Severity: Moderate CVSS3 score: 6.7

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---

The caller of dm_bm_read_lock() should not operate onthis invalid dm_block pointer, or it will lead to undefined result.For example, the dm_array_cursor incorrectly caches the invalid pointeron reading a faulty array block, causing a double release indm_array_cursor_end(), then hitting the BUG_ON in dm-bufio cache_put().Reproduce steps:1. initialize a cache devicedmsetup create cmeta --table "0 8192 linear /dev/sdc 0"dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"dmsetup create corig --table "0 524288 linear /dev/sdc $262144"dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"2. wipe the second array block offlinedmsteup remove cache cmeta cdata corigmapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 \2>/dev/null | hexdump -e '1/8 "%u\n"')ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) \2>/dev/null | hexdump -e '1/8 "%u\n"')dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock3. try reopen the cache devicedmsetup create cmeta --table "0 8192 linear /dev/sdc 0"dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"dmsetup create corig --table "0 524288 linear /dev/sdc $262144"dmsetup create cache --table "0 524288 cache /dev/mapper/cmeta \/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"Kernel logs:(snip)device-mapper: array: array_block_check failed: blocknr 0 != wanted 10device-mapper: block manager: array validator check failed for block 10device-mapper: array: get_ablock faileddevice-mapper: cache metadata: dm_array_cursor_next for mapping failed------------[ cut here ]------------kernel BUG at drivers/md/dm-bufio.c:638!Fix by setting the cached block pointer to NULL on errors.In addition to the reproducer described above, this fix can beverified using the "array_cursor/damaged" test in dm-unit: dm-unit run /pdata/array_cursor/damaged --kernel-dir

CVE-2022-48973 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:gpio: amd8111: Fix PCI device reference count leakfor_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() after the 'out' label. Since pci_dev_put() can handle NULLinput parameter, there is no problem for the 'Device not found' branch.For the normal path, add pci_dev_put() in amd_gpio_exit().

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.

CVE-2024-53150 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: Fix out of bounds reads when finding clock sourcesThe current USB-audio driver code doesn't check bLength of eachdescriptor at traversing for clock descriptors. That is, when adevice provides a bogus descriptor with a shorter bLength, the drivermight hit out-of-bounds reads.For addressing it, this patch adds sanity checks to the validatorfunctions for the clock descriptor traversal. When the descriptorlength is shorter than expected, it's skipped in the loop.For the clock source and clock multiplier descriptors, we can justcheck bLength against the sizeof() of each descriptor type.OTOH, the clock selector descriptor of UAC2 and UAC3 has an arrayof bNrInPins elements and two more fields at its tail, hence thosehave to be checked in addition to the sizeof() check.

This can leadto out-of-bounds access and undefined behavior if the buffer does nothave sufficient space.To address this, a check was added in acpi_nfit_ctl() to ensure thatbuf is not NULL and that buf_len is less than sizeof(*call_pkg)before accessing it. This ensures safe access to the members ofcall_pkg, including the nd_reserved2 array.

CVE-2024-57890 Severity: Moderate CVSS3 score: 6.6

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/uverbs: Prevent integer overflow issueIn the expression "cmd.wqe_size * cmd.wr_count", both variables are u32values that come from the user so the multiplication can lead to integerwrapping. Then we pass the result to uverbs_request_next_ptr() which alsocould potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)"multiplication can also overflow on 32bit systems although it's fine on64bit systems.This patch does two things. First, I've re-arranged the condition inuverbs_request_next_ptr() so that the use controlled variable "len" is onone side of the comparison by itself without any math. Then I've modifiedall the callers to use size_mul() for the multiplications.

Description: A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/bin/activate"). This means that attacker-controlled virtual environments are able to run commands when the virtual environment is activated. Virtual environments which are not created by an attacker or which aren't activated before being used (ie "./venv/bin/python") are not affected.

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.

CVE-2024-47745 Severity: Moderate CVSS3 score: 6.4

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. Otherwise, itpotentially permits an attacker to bypass a W^X policy enforced bySELinux.The bypass is similar to CVE-2016-10044, which bypass the same thing viaAIO and can be found in [1].The PoC:$ cat > test.cint main(void) { size_t pagesz = sysconf(_SC_PAGE_SIZE); int mfd = syscall(SYS_memfd_create, "test", 0); const char *buf = mmap(NULL, 4 * pagesz, PROT_READ | PROT_WRITE, MAP_SHARED, mfd, 0); unsigned int old = syscall(SYS_personality, 0xffffffff); syscall(SYS_personality, READ_IMPLIES_EXEC | old); syscall(SYS_remap_file_pages, buf, pagesz, 0, 2, 0); syscall(SYS_personality, old); // show the RWX page exists even if W^X policy is enforced int fd = open("/proc/self/maps", O_RDONLY); unsigned char buf2[1024]; while (1) { int ret = read(fd, buf2, 1024); if (ret <= 0) break; write(1, buf2, ret); } close(fd);}$ gcc test.c -o test$ ./test | grep rwx7f1836c34000-7f1836c35000 rwxs 00002000 00:01 2050 /memfd:test (deleted)[PM: subject line tweaks]

CVE-2024-53088 Severity: Moderate CVSS3 score: 6.3

Description: In the Linux kernel, the following vulnerability has been resolved:i40e: fix race condition by adding filter's intermediate sync stateFix a race condition in the i40e driver that leads to MAC/VLAN filtersbecoming corrupted and leaking. Address the issue that occurs underheavy load when multiple threads are concurrently modifying MAC/VLANfilters by setting mac and port VLAN.1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan().2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac().3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption.Reproduction steps:1. Spawn multiple VFs.2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host.3. Observe errors in dmesg:"Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX".Exact code for stable reproduction Intel can't open-source now.The fix involves implementing a new intermediate filter state,I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list.These filters cannot be deleted from the hash list directly butmust be removed using the full process.

CVE-2025-21753 Severity: Moderate CVSS3 score: 6.1

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix use-after-free when attempting to join an aborted transactionWhen we are trying to join the current transaction and if it's aborted,we read its 'aborted' field after unlocking fs_info->trans_lock andwithout holding any extra reference count on it. This means that aconcurrent task that is aborting the transaction may free the transactionbefore we read its 'aborted' field, leading to a use-after-free.Fix this by reading the 'aborted' field while holding fs_info->trans_locksince any freeing task must first acquire that lock and setfs_info->running_transaction to NULL before freeing the transaction.This was reported by syzbot and Dmitry with the following stack tracesfrom KASAN: ================================================================== BUG: KASAN: slab-use-after-free in join_transaction+0xd9b/0xda0 fs/btrfs/transaction.c:278 Read of size 4 at addr ffff888011839024 by task kworker/u4:9/1128 CPU: 0 UID: 0 PID: 1128 Comm: kworker/u4:9 Not tainted 6.13.0-rc7-syzkaller-00019-gc45323b7560e #0 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2~bpo12+1 04/01/2014 Workqueue: events_unbound btrfs_async_reclaim_data_space Call Trace: __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0x241/0x360 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0x169/0x550 mm/kasan/report.c:489 kasan_report+0x143/0x180 mm/kasan/report.c:602 join_transaction+0xd9b/0xda0 fs/btrfs/transaction.c:278 start_transaction+0xaf8/0x1670 fs/btrfs/transaction.c:697 flush_space+0x448/0xcf0 fs/btrfs/space-info.c:803 btrfs_async_reclaim_data_space+0x159/0x510 fs/btrfs/space-info.c:1321 process_one_work kernel/workqueue.c:3236 [inline] process_scheduled_works+0xa66/0x1840 kernel/workqueue.c:3317 worker_thread+0x870/0xd30 kernel/workqueue.c:3398 kthread+0x2f0/0x390 kernel/kthread.c:389 ret_from_fork+0x4b/0x80 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 Allocated by task 5315: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3f/0x80 mm/kasan/common.c:68 poison_kmalloc_redzone mm/kasan/common.c:377 [inline] __kasan_kmalloc+0x98/0xb0 mm/kasan/common.c:394 kasan_kmalloc include/linux/kasan.h:260 [inline] __kmalloc_cache_noprof+0x243/0x390 mm/slub.c:4329 kmalloc_noprof include/linux/slab.h:901 [inline] join_transaction+0x144/0xda0 fs/btrfs/transaction.c:308 start_transaction+0xaf8/0x1670 fs/btrfs/transaction.c:697 btrfs_create_common+0x1b2/0x2e0 fs/btrfs/inode.c:6572 lookup_open fs/namei.c:3649 [inline] open_last_lookups fs/namei.c:3748 [inline] path_openat+0x1c03/0x3590 fs/namei.c:3984 do_filp_open+0x27f/0x4e0 fs/namei.c:4014 do_sys_openat2+0x13e/0x1d0 fs/open.c:1402 do_sys_open fs/open.c:1417 [inline] __do_sys_creat fs/open.c:1495 [inline] __se_sys_creat fs/open.c:1489 [inline] __x64_sys_creat+0x123/0x170 fs/open.c:1489 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f Freed by task 5336: kasan_save_stack mm/kasan/common.c:47 [inline] kasan_save_track+0x3f/0x80 mm/kasan/common.c:68 kasan_save_free_info+0x40/0x50 mm/kasan/generic.c:582 poison_slab_object mm/kasan/common.c:247 [inline] __kasan_slab_free+0x59/0x70 mm/kasan/common.c:264 kasan_slab_free include/linux/kasan.h:233 [inline] slab_free_hook mm/slub.c:2353 [inline] slab_free mm/slub.c:4613 [inline] kfree+0x196/0x430 mm/slub.c:4761 cleanup_transaction fs/btrfs/transaction.c:2063 [inline] btrfs_commit_transaction+0x2c97/0x3720 fs/btrfs/transaction.c:2598 insert_balance_item+0x1284/0x20b0 fs/btrfs/volumes.c:3757 btrfs_balance+0x992/---truncated---

CVE-2022-49290 Severity: Moderate CVSS3 score: 6.0

Description: In the Linux kernel, the following vulnerability has been resolved:mac80211: fix potential double free on mesh joinWhile commit 6a01afcf8468 ("mac80211: mesh: Free ie data when leavingmesh") fixed a memory leak on mesh leave / teardown it introduced apotential memory corruption caused by a double free when rejoining themesh: ieee80211_leave_mesh() -> kfree(sdata->u.mesh.ie); ... ieee80211_join_mesh() -> copy_mesh_setup() -> old_ie = ifmsh->ie; -> kfree(old_ie);This double free / kernel panics can be reproduced by using wpa_supplicantwith an encrypted mesh (if set up without encryption via "iw" thenifmsh->ie is always NULL, which avoids this issue). And then calling: $ iw dev mesh0 mesh leave $ iw dev mesh0 mesh join my-meshNote that typically these commands are not used / working when usingwpa_supplicant. And it seems that wpa_supplicant or wpa_cli are goingthrough a NETDEV_DOWN/NETDEV_UP cycle between a mesh leave and mesh joinwhere the NETDEV_UP resets the mesh.ie to NULL via a memcpy ofdefault_mesh_setup in cfg80211_netdev_notifier_call, which then avoidsthe memory corruption, too.The issue was first observed in an application which was not usingwpa_supplicant but "Senf" instead, which implements its own calls tonl80211.Fixing the issue by removing the kfree()'ing of the mesh IE in the meshjoin function and leaving it solely up to the mesh leave to free themesh IE.

Description: In the Linux kernel, the following vulnerability has been resolved:uio_hv_generic: Don't free decrypted memoryIn 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 device UIO driver could free decrypted/shared pages ifset_memory_decrypted() fails. Check the decrypted field in the gpadlto decide whether to free the memory.

CVE-2024-47742 Severity: Moderate CVSS3 score: 6.0

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.

CVE-2019-1549 Severity: Moderate CVSS3 score: 5.9

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).

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

CVE-2024-46675 Severity: Moderate CVSS3 score: 5.8

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.

CVE-2024-53680 Severity: Moderate CVSS3 score: 5.8

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()Under certain kernel configurations when building with Clang/LLVM, thecompiler does not generate a return or jump as the terminatorinstruction for ip_vs_protocol_init(), triggering the following objtoolwarning during build time: vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()At runtime, this either causes an oops when trying to load the ipvsmodule or a boot-time panic if ipvs is built-in. This same issue hasbeen reported by the Intel kernel test robot previously.Digging deeper into both LLVM and the kernel code reveals this to be aundefined behavior problem. ip_vs_protocol_init() uses a on-stack bufferof 64 chars to store the registered protocol names and leaves ituninitialized after definition. The function calls strnlen() whenconcatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCEstrnlen() performs an extra step to check whether the last byte of theinput char buffer is a null character (commit 3009f891bb9f ("fortify:Allow strlen() and strnlen() to pass compile-time known lengths")).This, together with possibly other configurations, cause the followingIR to be generated: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 { %1 = alloca [64 x i8], align 16 ... 14: ; preds = %11 %15 = getelementptr inbounds i8, ptr %1, i64 63 %16 = load i8, ptr %15, align 1 %17 = tail call i1 @llvm.is.constant.i8(i8 %16) %18 = icmp eq i8 %16, 0 %19 = select i1 %17, i1 %18, i1 false br i1 %19, label %20, label %23 20: ; preds = %14 %21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23 ... 23: ; preds = %14, %11, %20 %24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24 ... }The above code calculates the address of the last char in the buffer(value %15) and then loads from it (value %16). Because the buffer isnever initialized, the LLVM GVN pass marks value %16 as undefined: %13 = getelementptr inbounds i8, ptr %1, i64 63 br i1 undef, label %14, label %17This gives later passes (SCCP, in particular) more DCE opportunities bypropagating the undef value further, and eventually removes everythingafter the load on the uninitialized stack location: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section ".init.text" align 16 !kcfi_type !11 { %1 = alloca [64 x i8], align 16 ... 12: ; preds = %11 %13 = getelementptr inbounds i8, ptr %1, i64 63 unreachable }In this way, the generated native code will just fall through to thenext function, as LLVM does not generate any code for the unreachable IRinstruction and leaves the function without a terminator.Zero the on-stack buffer to avoid this possible UB.

CVE-2019-1547 Severity: Moderate CVSS3 score: 5.5

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). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s).

CVE-2021-46987 Severity: Moderate CVSS3 score: 5.5

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---

Fix it by using dst_hold_safe() andchecking if a reference was actually taken before setting the dst.[1] dmesg WARN_ON log and following refcnt errors WARNING: CPU: 5 PID: 38 at include/net/dst.h:230 br_handle_egress_vlan_tunnel+0x10b/0x134 [bridge] Modules linked in: 8021q garp mrp bridge stp llc bonding ipv6 virtio_net CPU: 5 PID: 38 Comm: ksoftirqd/5 Kdump: loaded Tainted: G W 5.13.0-rc3+ #360 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014 RIP: 0010:br_handle_egress_vlan_tunnel+0x10b/0x134 [bridge] Code: e8 85 bc 01 e1 45 84 f6 74 90 45 31 f6 85 db 48 c7 c7 a0 02 19 a0 41 0f 94 c6 31 c9 31 d2 44 89 f6 e8 64 bc 01 e1 85 db 75 02 <0f> 0b 31 c9 31 d2 44 89 f6 48 c7 c7 70 02 19 a0 e8 4b bc 01 e1 49 RSP: 0018:ffff8881003d39e8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000001 RDI: ffffffffa01902a0 RBP: ffff8881040c6700 R08: 0000000000000000 R09: 0000000000000001 R10: 2ce93d0054fe0d00 R11: 54fe0d00000e0000 R12: ffff888109515000 R13: 0000000000000000 R14: 0000000000000001 R15: 0000000000000401 FS: 0000000000000000(0000) GS:ffff88822bf40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f42ba70f030 CR3: 0000000109926000 CR4: 00000000000006e0 Call Trace: br_handle_vlan+0xbc/0xca [bridge] __br_forward+0x23/0x164 [bridge] deliver_clone+0x41/0x48 [bridge] br_handle_frame_finish+0x36f/0x3aa [bridge] ? skb_dst+0x2e/0x38 [bridge] ? br_handle_ingress_vlan_tunnel+0x3e/0x1c8 [bridge] ? br_handle_frame_finish+0x3aa/0x3aa [bridge] br_handle_frame+0x2c3/0x377 [bridge] ? __skb_pull+0x33/0x51 ? vlan_do_receive+0x4f/0x36a ? br_handle_frame_finish+0x3aa/0x3aa [bridge] __netif_receive_skb_core+0x539/0x7c6 ? __list_del_entry_valid+0x16e/0x1c2 __netif_receive_skb_list_core+0x6d/0xd6 netif_receive_skb_list_internal+0x1d9/0x1fa gro_normal_list+0x22/0x3e dev_gro_receive+0x55b/0x600 ? detach_buf_split+0x58/0x140 napi_gro_receive+0x94/0x12e virtnet_poll+0x15d/0x315 [virtio_net] __napi_poll+0x2c/0x1c9 net_rx_action+0xe6/0x1fb __do_softirq+0x115/0x2d8 run_ksoftirqd+0x18/0x20 smpboot_thread_fn+0x183/0x19c ? smpboot_unregister_percpu_thread+0x66/0x66 kthread+0x10a/0x10f ? kthread_mod_delayed_work+0xb6/0xb6 ret_from_fork+0x22/0x30 ---[ end trace 49f61b07f775fd2b ]--- dst_release: dst:00000000c02d677a refcnt:-1 dst_release underflow

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.

Description: In the Linux kernel, the following vulnerability has been resolved:media: mxl111sf: change mutex_init() locationSyzbot reported, that mxl111sf_ctrl_msg() uses uninitializedmutex. The problem was in wrong mutex_init() location.Previous mutex_init(&state->msg_lock) call was in ->init() function, butdvb_usbv2_init() has this order of calls: dvb_usbv2_init() dvb_usbv2_adapter_init() dvb_usbv2_adapter_frontend_init() props->frontend_attach() props->init()Since mxl111sf_* devices call mxl111sf_ctrl_msg() in ->frontend_attach()internally we need to initialize state->msg_lock beforefrontend_attach(). To achieve it, ->probe() call added to all mxl111sf_*devices, which will simply initiaize mutex.

CVE-2022-48809 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2022-48853 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2022-49075 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix qgroup reserve overflow the qgroup limitWe use extent_changeset->bytes_changed in qgroup_reserve_data() to recordhow many bytes we set for EXTENT_QGROUP_RESERVED state. Currently thebytes_changed is set as "unsigned int", and it will overflow if we try tofallocate a range larger than 4GiB. The result is we reserve less bytesand eventually break the qgroup limit.Unlike regular buffered/direct write, which we use one changeset foreach ordered extent, which can never be larger than 256M. Forfallocate, we use one changeset for the whole range, thus it no longerrespects the 256M per extent limit, and caused the problem.The following example test script reproduces the problem: $ cat qgroup-overflow.sh #!/bin/bash DEV=/dev/sdj MNT=/mnt/sdj mkfs.btrfs -f $DEV mount $DEV $MNT # Set qgroup limit to 2GiB. btrfs quota enable $MNT btrfs qgroup limit 2G $MNT # Try to fallocate a 3GiB file. This should fail. echo echo "Try to fallocate a 3GiB file..." fallocate -l 3G $MNT/3G.file # Try to fallocate a 5GiB file. echo echo "Try to fallocate a 5GiB file..." fallocate -l 5G $MNT/5G.file # See we break the qgroup limit. echo sync btrfs qgroup show -r $MNT umount $MNTWhen running the test: $ ./qgroup-overflow.sh (...) Try to fallocate a 3GiB file... fallocate: fallocate failed: Disk quota exceeded Try to fallocate a 5GiB file... qgroupid rfer excl max_rfer -------- ---- ---- -------- 0/5 5.00GiB 5.00GiB 2.00GiBSince we have no control of how bytes_changed is used, it's better toset it to u64.

Use theirqsave/irqrestore instead.The backtrace for the reference:[ 2.752010] ------------[ cut here ]------------[ 2.756769] raw_local_irq_restore() called with IRQs enabled[ 2.762596] WARNING: CPU: 4 PID: 1 at kernel/locking/irqflag-debug.c:10 warn_bogus_irq_restore+0x34/0x50[ 2.772338] Modules linked in:[ 2.775487] CPU: 4 PID: 1 Comm: swapper/0 Tainted: G S 5.17.0-rc6-00384-ge330d0d82eff-dirty #684[ 2.781384] Freeing initrd memory: 46024K[ 2.785839] pstate: 60400005 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)[ 2.785841] pc : warn_bogus_irq_restore+0x34/0x50[ 2.785844] lr : warn_bogus_irq_restore+0x34/0x50[ 2.785846] sp : ffff80000805b7d0[ 2.785847] x29: ffff80000805b7d0 x28: 0000000000000000 x27: 0000000000000002[ 2.785850] x26: ffffd40e80930b18 x25: ffff7ee2329192b8 x24: ffff7edfc9f60800[ 2.785853] x23: ffffd40e80930b18 x22: ffffd40e80930d30 x21: ffff7edfc0dffa00[ 2.785856] x20: ffff7edfc09e3768 x19: 0000000000000000 x18: ffffffffffffffff[ 2.845775] x17: 6572206f74206465 x16: 6c696166203a3030 x15: ffff80008805b4f7[ 2.853108] x14: 0000000000000000 x13: ffffd40e809550b0 x12: 00000000000003d8[ 2.860441] x11: 0000000000000148 x10: ffffd40e809550b0 x9 : ffffd40e809550b0[ 2.867774] x8 : 00000000ffffefff x7 : ffffd40e809ad0b0 x6 : ffffd40e809ad0b0[ 2.875107] x5 : 000000000000bff4 x4 : 0000000000000000 x3 : 0000000000000000[ 2.882440] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff7edfc03a8000[ 2.889774] Call trace:[ 2.892290] warn_bogus_irq_restore+0x34/0x50[ 2.896770] _raw_spin_unlock_irqrestore+0x94/0xa0[ 2.901690] genpd_unlock_spin+0x20/0x30[ 2.905724] genpd_add_device+0x100/0x2d0[ 2.909850] __genpd_dev_pm_attach+0xa8/0x23c[ 2.914329] genpd_dev_pm_attach_by_id+0xc4/0x190[ 2.919167] genpd_dev_pm_attach_by_name+0x3c/0xd0[ 2.924086] dev_pm_domain_attach_by_name+0x24/0x30[ 2.929102] psci_dt_attach_cpu+0x24/0x90[ 2.933230] psci_cpuidle_probe+0x2d4/0x46c[ 2.937534] platform_probe+0x68/0xe0[ 2.941304] really_probe.part.0+0x9c/0x2fc[ 2.945605] __driver_probe_device+0x98/0x144[ 2.950085] driver_probe_device+0x44/0x15c[ 2.954385] __device_attach_driver+0xb8/0x120[ 2.958950] bus_for_each_drv+0x78/0xd0[ 2.962896] __device_attach+0xd8/0x180[ 2.966843] device_initial_probe+0x14/0x20[ 2.971144] bus_probe_device+0x9c/0xa4[ 2.975092] device_add+0x380/0x88c[ 2.978679] platform_device_add+0x114/0x234[ 2.983067] platform_device_register_full+0x100/0x190[ 2.988344] psci_idle_init+0x6c/0xb0[ 2.992113] do_one_initcall+0x74/0x3a0[ 2.996060] kernel_init_freeable+0x2fc/0x384[ 3.000543] kernel_init+0x28/0x130[ 3.004132] ret_from_fork+0x10/0x20[ 3.007817] irq event stamp: 319826[ 3.011404] hardirqs last enabled at (319825): [] __up_console_sem+0x78/0x84[ 3.020332] hardirqs last disabled at (319826): [] el1_dbg+0x24/0x8c[ 3.028458] softirqs last enabled at (318312): [] _stext+0x410/0x588[ 3.036678] softirqs last disabled at (318299): [] __irq_exit_rcu+0x158/0x174[ 3.045607] ---[ end trace 0000000000000000 ]---

Description: In the Linux kernel, the following vulnerability has been resolved:kernel/resource: fix kfree() of bootmem memory againSince commit ebff7d8f270d ("mem hotunplug: fix kfree() of bootmemmemory"), we could get a resource allocated during boot viaalloc_resource(). And it's required to release the resource usingfree_resource(). Howerver, many people use kfree directly which willresult in kernel BUG. In order to fix this without fixing every callsite, just leak a couple of bytes in such corner case.

However just after the queue was stopped, an in-flightibmvnic_complete_tx() could have restarted the queue even as the reset isprogressing.Since the queue was restarted we could get a call to ibmvnic_xmit() whichcan then access the bad tx_scrq (or other fields).We cannot however simply have ibmvnic_complete_tx() check the ->resettingbit and skip starting the queue. This can race at the "back-end" of a goodreset which just restarted the queue but has not cleared the ->resettingbit yet. If we skip restarting the queue due to ->resetting being true,the queue would remain stopped indefinitely potentially leading to transmittimeouts.IOW ->resetting is too broad for this purpose. Instead use a new flagthat indicates whether or not the queues are active. Only the open/reset paths control when the queues are active. ibmvnic_complete_tx()and others wake up the queue only if the queue is marked active.So we will have: A. reset/open thread in ibmvnic_cleanup() and __ibmvnic_open() ->resetting = true ->tx_queues_active = false disable tx queues ... ->tx_queues_active = true start tx queues B. Tx interrupt in ibmvnic_complete_tx(): if (->tx_queues_active) netif_wake_subqueue();To ensure that ->tx_queues_active and state of the queues are consistent,we need a lock which: - must also be taken in the interrupt path (ibmvnic_complete_tx()) - shared across the multiple---truncated---

CVE-2022-49272 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and mmap_locksyzbot caught a potential deadlock between the PCMruntime->buffer_mutex and the mm->mmap_lock. It was brought by therecent fix to cover the racy read/write and other ioctls, and in thatcommit, I overlooked a (hopefully only) corner case that may take therevert lock, namely, the OSS mmap. The OSS mmap operationexceptionally allows to re-configure the parameters inside the OSSmmap syscall, where mm->mmap_mutex is already held. Meanwhile, thecopy_from/to_user calls at read/write operations also take themm->mmap_lock internally, hence it may lead to a AB/BA deadlock.A similar problem was already seen in the past and we fixed it with arefcount (in commit b248371628aa). The former fix covered only thecall paths with OSS read/write and OSS ioctls, while we need to coverthe concurrent access via both ALSA and OSS APIs now.This patch addresses the problem above by replacing the buffer_mutexlock in the read/write operations with a refcount similar as we'veused for OSS. The new field, runtime->buffer_accessing, keeps thenumber of concurrent read/write operations. Unlike the formerbuffer_mutex protection, this protects only around thecopy_from/to_user() calls; the other codes are basically protected bythe PCM stream lock. The refcount can be a negative, meaning blockedby the ioctls. If a negative value is seen, the read/write abortswith -EBUSY. In the ioctl side, OTOH, they check this refcount, too,and set to a negative value for blocking unless it's already beingaccessed.

CVE-2022-49292 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ALSA: oss: Fix PCM OSS buffer allocation overflowWe've got syzbot reports hitting INT_MAX overflow at vmalloc()allocation that is called from snd_pcm_plug_alloc(). Although weapply the restrictions to input parameters, it's based only on thehw_params of the underlying PCM device. Since the PCM OSS layerallocates a temporary buffer for the data conversion, the size maybecome unexpectedly large when more channels or higher rates is given;in the reported case, it went over INT_MAX, hence it hits WARN_ON().This patch is an attempt to avoid such an overflow and an allocationfor too large buffers. First off, it adds the limit of 1MB as theupper bound for period bytes. This must be large enough for all usecases, and we really don't want to handle a larger temporary bufferthan this size. The size check is performed at two places, where theoriginal period bytes is calculated and where the plugin buffer sizeis calculated.In addition, the driver uses array_size() and array3_size() formultiplications to catch overflows for the converted period size andbuffer bytes.

Description: In the Linux kernel, the following vulnerability has been resolved:rtl818x: Prevent using not initialized queuesUsing not existing queues can panic the kernel with rtl8180/rtl8185 cards.Ignore the skb priority for those cards, they only have one tx queue. PierreAsselin (pa@panix.com) reported the kernel crash in the Gentoo forum:https://forums.gentoo.org/viewtopic-t-1147832-postdays-0-postorder-asc-start-25.htmlHe also confirmed that this patch fixes the issue. In summary this happened:After updating wpa_supplicant from 2.9 to 2.10 the kernel crashed with a"divide error: 0000" when connecting to an AP. Control port tx now tries touse IEEE80211_AC_VO for the priority, which wpa_supplicants starts to use in2.10.Since only the rtl8187se part of the driver supports QoS, the priorityof the skb is set to IEEE80211_AC_BE (2) by mac80211 for rtl8180/rtl8185cards.rtl8180 is then unconditionally reading out the priority and finally crashes ondrivers/net/wireless/realtek/rtl818x/rtl8180/dev.c line 544 without thispatch: idx = (ring->idx + skb_queue_len(&ring->queue)) % ring->entries"ring->entries" is zero for rtl8180/rtl8185 cards, tx_ring[2] never gotinitialized.

But there are too many printk() on thekmalloc() path, and kmalloc() can be called from anywhere, so changingprintk() to printk_deferred() is too complicated and inelegant.Therefore, this patch chooses to specify __GFP_NOWARN to kmalloc(), sothat printk() will not be called, and this deadlock problem can beavoided.Syzbot reported the following lockdep error:======================================================WARNING: possible circular locking dependency detected5.4.143-00237-g08ccc19a-dirty #10 Not tainted------------------------------------------------------syz-executor.4/29420 is trying to acquire lock:ffffffff8aedb2a0 (console_owner){....}-{0:0}, at: console_trylock_spinning kernel/printk/printk.c:1752 [inline]ffffffff8aedb2a0 (console_owner){....}-{0:0}, at: vprintk_emit+0x2ca/0x470 kernel/printk/printk.c:2023but task is already holding lock:ffff8880119c9158 (&port->lock){-.-.}-{2:2}, at: pty_write+0xf4/0x1f0 drivers/tty/pty.c:120which lock already depends on the new lock.the existing dependency chain (in reverse order) is:-> #2 (&port->lock){-.-.}-{2:2}: __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline] _raw_spin_lock_irqsave+0x35/0x50 kernel/locking/spinlock.c:159 tty_port_tty_get drivers/tty/tty_port.c:288 [inline] <-- lock(&port->lock); tty_port_default_wakeup+0x1d/0xb0 drivers/tty/tty_port.c:47 serial8250_tx_chars+0x530/0xa80 drivers/tty/serial/8250/8250_port.c:1767 serial8250_handle_irq.part.0+0x31f/0x3d0 drivers/tty/serial/8250/8250_port.c:1854 serial8250_handle_irq drivers/tty/serial/8250/8250_port.c:1827 [inline] <-- lock(&port_lock_key); serial8250_default_handle_irq+0xb2/0x220 drivers/tty/serial/8250/8250_port.c:1870 serial8250_interrupt+0xfd/0x200 drivers/tty/serial/8250/8250_core.c:126 __handle_irq_event_percpu+0x109/0xa50 kernel/irq/handle.c:156 [...]-> #1 (&port_lock_key){-.-.}-{2:2}: __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline] _raw_spin_lock_irqsave+0x35/0x50 kernel/locking/spinlock.c:159 serial8250_console_write+0x184/0xa40 drivers/tty/serial/8250/8250_port.c:3198 <-- lock(&port_lock_key); call_console_drivers kernel/printk/printk.c:1819 [inline] console_unlock+0x8cb/0xd00 kernel/printk/printk.c:2504 vprintk_emit+0x1b5/0x470 kernel/printk/printk.c:2024 <-- lock(console_owner); vprintk_func+0x8d/0x250 kernel/printk/printk_safe.c:394 printk+0xba/0xed kernel/printk/printk.c:2084 register_console+0x8b3/0xc10 kernel/printk/printk.c:2829 univ8250_console_init+0x3a/0x46 drivers/tty/serial/8250/8250_core.c:681 console_init+0x49d/0x6d3 kernel/printk/printk.c:2915 start_kernel+0x5e9/0x879 init/main.c:713 secondary_startup_64+0xa4/0xb0 arch/x86/kernel/head_64.S:241-> #0 (console_owner){....}-{0:0}: [...] lock_acquire+0x127/0x340 kernel/locking/lockdep.c:4734 console_trylock_spinning kernel/printk/printk.c:1773 ---truncated---

Since code blindly uses this member forarray indexing adding sanity check is the easiest fix for that.hdw->workpoll initialization moved upper to prevent warning in__flush_work.

CVE-2022-49519 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ath10k: skip ath10k_halt during suspend for driver state RESTARTINGDouble free crash is observed when FW recovery(caused by wmitimeout/crash) is followed by immediate suspend event. The FW recoveryis triggered by ath10k_core_restart() which calls driver clean up viaath10k_halt(). When the suspend event occurs between the FW recovery,the restart worker thread is put into frozen state until suspend completes.The suspend event triggers ath10k_stop() which again triggers ath10k_halt()The double invocation of ath10k_halt() causes ath10k_htt_rx_free() to becalled twice(Note: ath10k_htt_rx_alloc was not called by restart workerthread because of its frozen state), causing the crash.To fix this, during the suspend flow, skip call to ath10k_halt() inath10k_stop() when the current driver state is ATH10K_STATE_RESTARTING.Also, for driver state ATH10K_STATE_RESTARTING, callath10k_wait_for_suspend() in ath10k_stop(). This is because call toath10k_wait_for_suspend() is skipped later in[ath10k_halt() > ath10k_core_stop()] for the driver stateATH10K_STATE_RESTARTING.The frozen restart worker thread will be cancelled during resume when thedevice comes out of suspend.Below is the crash stack for reference:[ 428.469167] ------------[ cut here ]------------[ 428.469180] kernel BUG at mm/slub.c:4150![ 428.469193] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI[ 428.469219] Workqueue: events_unbound async_run_entry_fn[ 428.469230] RIP: 0010:kfree+0x319/0x31b[ 428.469241] RSP: 0018:ffffa1fac015fc30 EFLAGS: 00010246[ 428.469247] RAX: ffffedb10419d108 RBX: ffff8c05262b0000[ 428.469252] RDX: ffff8c04a8c07000 RSI: 0000000000000000[ 428.469256] RBP: ffffa1fac015fc78 R08: 0000000000000000[ 428.469276] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 428.469285] Call Trace:[ 428.469295] ? dma_free_attrs+0x5f/0x7d[ 428.469320] ath10k_core_stop+0x5b/0x6f[ 428.469336] ath10k_halt+0x126/0x177[ 428.469352] ath10k_stop+0x41/0x7e[ 428.469387] drv_stop+0x88/0x10e[ 428.469410] __ieee80211_suspend+0x297/0x411[ 428.469441] rdev_suspend+0x6e/0xd0[ 428.469462] wiphy_suspend+0xb1/0x105[ 428.469483] ? name_show+0x2d/0x2d[ 428.469490] dpm_run_callback+0x8c/0x126[ 428.469511] ? name_show+0x2d/0x2d[ 428.469517] __device_suspend+0x2e7/0x41b[ 428.469523] async_suspend+0x1f/0x93[ 428.469529] async_run_entry_fn+0x3d/0xd1[ 428.469535] process_one_work+0x1b1/0x329[ 428.469541] worker_thread+0x213/0x372[ 428.469547] kthread+0x150/0x15f[ 428.469552] ? pr_cont_work+0x58/0x58[ 428.469558] ? kthread_blkcg+0x31/0x31Tested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00288-QCARMSWPZ-1

CVE-2022-49530 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:drm/amd/pm: fix double free in si_parse_power_table()In function si_parse_power_table(), array adev->pm.dpm.ps and its memberis allocated. If the allocation of each member fails, the array itselfis freed and returned with an error code. However, the array is laterfreed again in si_dpm_fini() function which is called when the functionreturns an error.This leads to potential double free of the array adev->pm.dpm.ps, aswell as leak of its array members, since the members are not freed inthe allocation function and the array is not nulled when freed.In addition adev->pm.dpm.num_ps, which keeps track of the allocatedarray member, is not updated until the member allocation issuccessfully finished, this could also lead to either use after free,or uninitialized variable access in si_dpm_fini().Fix this by postponing the free of the array until si_dpm_fini() andincrement adev->pm.dpm.num_ps everytime the array member is allocated.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGIIf lpfc_issue_els_flogi() fails and returns non-zero status, the nodereference count is decremented to trigger the release of the nodeliststructure. However, if there is a prior registration or dev-loss-evt workpending, the node may be released prematurely. When dev-loss-evtcompletes, the released node is referenced causing a use-after-free nullpointer dereference.Similarly, when processing non-zero ELS PLOGI completion status inlpfc_cmpl_els_plogi(), the ndlp flags are checked for a transportregistration before triggering node removal. If dev-loss-evt work ispending, the node may be released prematurely and a subsequent call tolpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference.Add test for pending dev-loss before decrementing the node reference countfor FLOGI, PLOGI, PRLI, and ADISC handling.

CVE-2022-49605 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:igc: Reinstate IGC_REMOVED logic and implement it properlyThe initially merged version of the igc driver code (via commit146740f9abc4, "igc: Add support for PF") contained the followingIGC_REMOVED checks in the igc_rd32/wr32() MMIO accessors: u32 igc_rd32(struct igc_hw *hw, u32 reg) { u8 __iomem *hw_addr = READ_ONCE(hw->hw_addr); u32 value = 0; if (IGC_REMOVED(hw_addr)) return ~value; value = readl(&hw_addr[reg]); /* reads should not return all F's */ if (!(~value) && (!reg || !(~readl(hw_addr)))) hw->hw_addr = NULL; return value; }And: #define wr32(reg, val) \ do { \ u8 __iomem *hw_addr = READ_ONCE((hw)->hw_addr); \ if (!IGC_REMOVED(hw_addr)) \ writel((val), &hw_addr[(reg)]); \ } while (0)E.g. igb has similar checks in its MMIO accessors, and has a similarmacro E1000_REMOVED, which is implemented as follows: #define E1000_REMOVED(h) unlikely(!(h))These checks serve to detect and take note of an 0xffffffff MMIO readreturn from the device, which can be caused by a PCIe link flap or someother kind of PCI bus error, and to avoid performing MMIO reads andwrites from that point onwards.However, the IGC_REMOVED macro was not originally implemented: #ifndef IGC_REMOVED #define IGC_REMOVED(a) (0) #endif /* IGC_REMOVED */This led to the IGC_REMOVED logic to be removed entirely in asubsequent commit (commit 3c215fb18e70, "igc: remove IGC_REMOVEDfunction"), with the rationale that such checks matter only forvirtualization and that igc does not support virtualization -- but aPCIe device can become detached even without virtualization being inuse, and without proper checks, a PCIe bus error affecting an igcadapter will lead to various NULL pointer dereferences, as the firstaccess after the error will set hw->hw_addr to NULL, and subsequentaccesses will blindly dereference this now-NULL pointer.This patch reinstates the IGC_REMOVED checks in igc_rd32/wr32(), andimplements IGC_REMOVED the way it is done for igb, by checking for theunlikely() case of hw_addr being NULL. This change prevents the oopsesseen when a PCIe link flap occurs on an igc adapter.

As such there is noserialization to avoid this race.Change perf_event_set_output() to take both e1->mmap_mutex ande2->mmap_mutex to alleviate that problem. Additionally, have the loopin perf_mmap() detach the rb directly, this avoids having to wait forthe concurrent perf_mmap_close() to get around to doing it to makeprogress.

CVE-2022-49661 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:can: gs_usb: gs_usb_open/close(): fix memory leakThe gs_usb driver appears to suffer from a malady common to many USBCAN adapter drivers in that it performs usb_alloc_coherent() toallocate a number of USB request blocks (URBs) for RX, and then laterrelies on usb_kill_anchored_urbs() to free them, but this doesn'tactually free them. As a result, this may be leaking DMA memory that'sbeen used by the driver.This commit is an adaptation of the techniques found in the esd_usb2driver where a similar design pattern led to a memory leak. Itexplicitly frees the RX URBs and their DMA memory via a call tousb_free_coherent(). Since the RX URBs were allocated in thegs_can_open(), we remove them in gs_can_close() rather than in thedisconnect function as was done in esd_usb2.For more information, see the 928150fad41b ("can: esd_usb2: fix memoryleak").

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.

CVE-2023-52854 Severity: Moderate CVSS3 score: 5.5

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: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.

BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat] Use-after-free read at 0x00000000bc56fddf (in kfence-#142): adf_device_reset_worker+0x38/0xa0 [intel_qat] process_one_work+0x173/0x340To resolve this race condition, the memory associated to the containerof the work_struct is freed on the worker if the timeout expired,otherwise on the function that schedules the worker.The timeout detection can be done by checking if the caller isstill waiting for completion or not by using completion_done() function.

CVE-2024-26976 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Always flush async #PF workqueue when vCPU is being destroyedAlways flush the per-vCPU async #PF workqueue when a vCPU is clearing itscompletion queue, e.g. when a VM and all its vCPUs is being destroyed.KVM must ensure that none of its workqueue callbacks is running when thelast reference to the KVM _module_ is put. 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---

CVE-2024-26982 Severity: Moderate CVSS3 score: 5.5

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.

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:Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()l2cap_le_flowctl_init() can cause both div-by-zero and an integeroverflow since hdev->le_mtu may not fall in the valid range.Move MTU from hci_dev to hci_conn to validate MTU and stop the connectionprocess earlier if MTU is invalid.Also, add a missing validation in read_buffer_size() and make it returnan error value if the validation fails.Now hci_conn_add() returns ERR_PTR() as it can fail due to the both akzalloc failure and invalid MTU value.divide error: 0000 [#1] PREEMPT SMP KASAN NOPTICPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014Workqueue: hci0 hci_rx_workRIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8db7 88 00 00 00 4c 89 f0 48 c1 e8 03 42RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66fRBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaaR10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0PKRU: 55555554Call Trace: l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 Modules linked in:---[ end trace 0000000000000000 ]---

CVE-2024-42098 Severity: Moderate CVSS3 score: 5.5

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.

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.

CVE-2024-46695 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-46744 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-46745 Severity: Moderate CVSS3 score: 5.5

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 repro calls connect() to vxcan1, removes vxcan1, and callsconnect() with ifindex == 0.Calling connect() for a BCM socket allocates a proc entry.Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().However, removing the bound device resets bcm_sk(sk)->bound to 0in bcm_notify().The 2nd connect() tries to allocate a proc entry with the samename and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking theoriginal proc entry.Since the proc entry is available only for connect()ed sockets,let's clean up the entry when the bound netdev is unregistered.[0]:proc_dir_entry 'can-bcm/2456' already registeredWARNING: CPU: 1 PID: 394 at fs/proc/generic.c:376 proc_register+0x645/0x8f0 fs/proc/generic.c:375Modules linked in:CPU: 1 PID: 394 Comm: syz-executor403 Not tainted 6.10.0-rc7-g852e42cc2dd4Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014RIP: 0010:proc_register+0x645/0x8f0 fs/proc/generic.c:375Code: 00 00 00 00 00 48 85 ed 0f 85 97 02 00 00 4d 85 f6 0f 85 9f 02 00 00 48 c7 c7 9b cb cf 87 48 89 de 4c 89 fa e8 1c 6f eb fe 90 <0f> 0b 90 90 48 c7 c7 98 37 99 89 e8 cb 7e 22 05 bb 00 00 00 10 48RSP: 0018:ffa0000000cd7c30 EFLAGS: 00010246RAX: 9e129be1950f0200 RBX: ff1100011b51582c RCX: ff1100011857cd80RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000002RBP: 0000000000000000 R08: ffd400000000000f R09: ff1100013e78cac0R10: ffac800000cd7980 R11: ff1100013e12b1f0 R12: 0000000000000000R13: 0000000000000000 R14: 0000000000000000 R15: ff1100011a99a2ecFS: 00007fbd7086f740(0000) GS:ff1100013fd00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00000000200071c0 CR3: 0000000118556004 CR4: 0000000000771ef0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400PKRU: 55555554Call Trace: proc_create_net_single+0x144/0x210 fs/proc/proc_net.c:220 bcm_connect+0x472/0x840 net/can/bcm.c:1673 __sys_connect_file net/socket.c:2049 [inline] __sys_connect+0x5d2/0x690 net/socket.c:2066 __do_sys_connect net/socket.c:2076 [inline] __se_sys_connect net/socket.c:2073 [inline] __x64_sys_connect+0x8f/0x100 net/socket.c:2073 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xd9/0x1c0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x4b/0x53RIP: 0033:0x7fbd708b0e5dCode: ff c3 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 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 8b 0d 73 9f 1b 00 f7 d8 64 89 01 48RSP: 002b:00007fff8cd33f08 EFLAGS: 00000246 ORIG_RAX: 000000000000002aRAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007fbd708b0e5dRDX: 0000000000000010 RSI: 0000000020000040 RDI: 0000000000000003RBP: 0000000000000000 R08: 0000000000000040 R09: 0000000000000040R10: 0000000000000040 R11: 0000000000000246 R12: 00007fff8cd34098R13: 0000000000401280 R14: 0000000000406de8 R15: 00007fbd70ab9000 remove_proc_entry: removing non-empty directory 'net/can-bcm', leaking at least '2456'

CVE-2024-46787 Severity: Moderate CVSS3 score: 5.5

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.

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.

(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.

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.

CVE-2024-47809 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:dlm: fix possible lkb_resource null dereferenceThis patch fixes a possible null pointer dereference when this function iscalled from request_lock() as lkb->lkb_resource is not assigned yet,only after validate_lock_args() by calling attach_lkb(). Another issueis that a resource name could be a non printable bytearray and we cannotassume to be ASCII coded.The log functionality is probably never being hit when DLM is used innormal way and no debug logging is enabled. The null pointer dereferencecan only occur on a new created lkb that does not have the resourceassigned yet, it probably never hits the null pointer dereference but weshould be sure that other changes might not change this behaviour and weactually can hit the mentioned null pointer dereference.In this patch we just drop the printout of the resource name, the lkb idis enough to make a possible connection to a resource name if thisexists.

CVE-2024-49881 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: update orig_path in ext4_find_extent()In ext4_find_extent(), if the path is not big enough, we free it and set*orig_path to NULL. But after reallocating and successfully initializingthe path, we don't update *orig_path, in which case the caller gets avalid path but a NULL ppath, and this may cause a NULL pointer dereferenceor a path memory leak. For example:ext4_split_extent path = *ppath = 2000 ext4_find_extent if (depth > path[0].p_maxdepth) kfree(path = 2000); *orig_path = path = NULL; path = kcalloc() = 3000 ext4_split_extent_at(*ppath = NULL) path = *ppath; ex = path[depth].p_ext; // NULL pointer dereference!==================================================================BUG: kernel NULL pointer dereference, address: 0000000000000010CPU: 6 UID: 0 PID: 576 Comm: fsstress Not tainted 6.11.0-rc2-dirty #847RIP: 0010:ext4_split_extent_at+0x6d/0x560Call Trace: ext4_split_extent.isra.0+0xcb/0x1b0 ext4_ext_convert_to_initialized+0x168/0x6c0 ext4_ext_handle_unwritten_extents+0x325/0x4d0 ext4_ext_map_blocks+0x520/0xdb0 ext4_map_blocks+0x2b0/0x690 ext4_iomap_begin+0x20e/0x2c0[...]==================================================================Therefore, *orig_path is updated when the extent lookup succeeds, so thatthe caller can safely use path or *ppath.

CVE-2024-49938 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-49958 Severity: Moderate CVSS3 score: 5.5

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.

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.

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. Thanks.

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.

CVE-2024-50106 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-50195 Severity: Moderate CVSS3 score: 5.5

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.

CVE-2024-50273 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: reinitialize delayed ref list after deleting it from the listAt insert_delayed_ref() if we need to update the action of an existingref to BTRFS_DROP_DELAYED_REF, we delete the ref from its ref head'sref_add_list using list_del(), which leaves the ref's add_list membernot reinitialized, as list_del() sets the next and prev members of thelist to LIST_POISON1 and LIST_POISON2, respectively.If later we end up calling drop_delayed_ref() against the ref, which canhappen during merging or when destroying delayed refs due to a transactionabort, we can trigger a crash since at drop_delayed_ref() we calllist_empty() against the ref's add_list, which returns false sincethe list was not reinitialized after the list_del() and as a consequencewe call list_del() again at drop_delayed_ref(). This results in aninvalid list access since the next and prev members are set to poisonpointers, resulting in a splat if CONFIG_LIST_HARDENED andCONFIG_DEBUG_LIST are set or invalid poison pointer dereferencesotherwise.So fix this by deleting from the list with list_del_init() instead.

CVE-2024-53058 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB dataIn case the non-paged data of a SKB carries protocol header and protocolpayload to be transmitted on a certain platform that the DMA AXI addresswidth is configured to 40-bit/48-bit, or the size of the non-paged datais bigger than TSO_MAX_BUFF_SIZE on a certain platform that the DMA AXIaddress width is configured to 32-bit, then this SKB requires at leasttwo DMA transmit descriptors to serve it.For example, three descriptors are allocated to split one DMA buffermapped from one piece of non-paged data: dma_desc[N + 0], dma_desc[N + 1], dma_desc[N + 2].Then three elements of tx_q->tx_skbuff_dma[] will be allocated to holdextra information to be reused in stmmac_tx_clean(): tx_q->tx_skbuff_dma[N + 0], tx_q->tx_skbuff_dma[N + 1], tx_q->tx_skbuff_dma[N + 2].Now we focus on tx_q->tx_skbuff_dma[entry].buf, which is the DMA bufferaddress returned by DMA mapping call. stmmac_tx_clean() will try tounmap the DMA buffer _ONLY_IF_ tx_q->tx_skbuff_dma[entry].bufis a valid buffer address.The expected behavior that saves DMA buffer address of this non-pageddata to tx_q->tx_skbuff_dma[entry].buf is: tx_q->tx_skbuff_dma[N + 0].buf = NULL; tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = dma_map_single();Unfortunately, the current code misbehaves like this: tx_q->tx_skbuff_dma[N + 0].buf = dma_map_single(); tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = NULL;On the stmmac_tx_clean() side, when dma_desc[N + 0] is closed by theDMA engine, tx_q->tx_skbuff_dma[N + 0].buf is a valid buffer addressobviously, then the DMA buffer will be unmapped immediately.There may be a rare case that the DMA engine does not finish thepending dma_desc[N + 1], dma_desc[N + 2] yet. Now things will gohorribly wrong, DMA is going to access a unmapped/unreferenced memoryregion, corrupted data will be transmited or iommu fault will betriggered :(In contrast, the for-loop that maps SKB fragments behaves perfectlyas expected, and that is how the driver should do for both non-pageddata and paged frags actually.This patch corrects DMA map/unmap sequences by fixing the array indexfor tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.Tested and verified on DWXGMAC CORE 3.20a

CVE-2024-53140 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:netlink: terminate outstanding dump on socket closeNetlink supports iterative dumping of data. It provides the familiesthe following ops: - start - (optional) kicks off the dumping process - dump - actual dump helper, keeps getting called until it returns 0 - done - (optional) pairs with .start, can be used for cleanupThe whole process is asynchronous and the repeated calls to .dumpdon't actually happen in a tight loop, but rather are triggeredin response to recvmsg() on the socket.This gives the user full control over the dump, but also means thatthe user can close the socket without getting to the end of the dump.To make sure .start is always paired with .done we check if thereis an ongoing dump before freeing the socket, and if so call .done.The complication is that sockets can get freed from BH and .doneis allowed to sleep. So we use a workqueue to defer the call, whenneeded.Unfortunately this does not work correctly. What we defer is notthe cleanup but rather releasing a reference on the socket.We have no guarantee that we own the last reference, if someoneelse holds the socket they may release it in BH and we're backto square one.The whole dance, however, appears to be unnecessary. Only the usercan interact with dumps, so we can clean up when socket is closed.And close always happens in process context. Some async code maystill access the socket after close, queue notification skbs to it etc.but no dumps can start, end or otherwise make progress.Delete the workqueue and flush the dump state directly from the releasehandler. Note that further cleanup is possible in -next, for instancewe now always call .done before releasing the main module reference,so dump doesn't have to take a reference of its own.

See MS-SMB23.3.5.4.Commit b0abcd65ec54 ("smb: client: fix UAF in async decryption") addeda @server->cipher_type check to conditionally callsmb3_crypto_aead_allocate(), but that check would always be false as@server->cipher_type is unset for SMB3.02.Fix the following KASAN splat by setting @server->cipher_type forSMB3.02 as well.mount.cifs //srv/share /mnt -o vers=3.02,seal,...BUG: KASAN: null-ptr-deref in crypto_aead_setkey+0x2c/0x130Read of size 8 at addr 0000000000000020 by task mount.cifs/1095CPU: 1 UID: 0 PID: 1095 Comm: mount.cifs Not tainted 6.12.0 #1Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-3.fc4104/01/2014Call Trace: dump_stack_lvl+0x5d/0x80 ? crypto_aead_setkey+0x2c/0x130 kasan_report+0xda/0x110 ? crypto_aead_setkey+0x2c/0x130 crypto_aead_setkey+0x2c/0x130 crypt_message+0x258/0xec0 [cifs] ? __asan_memset+0x23/0x50 ? __pfx_crypt_message+0x10/0x10 [cifs] ? mark_lock+0xb0/0x6a0 ? hlock_class+0x32/0xb0 ? mark_lock+0xb0/0x6a0 smb3_init_transform_rq+0x352/0x3f0 [cifs] ? lock_acquire.part.0+0xf4/0x2a0 smb_send_rqst+0x144/0x230 [cifs] ? __pfx_smb_send_rqst+0x10/0x10 [cifs] ? hlock_class+0x32/0xb0 ? smb2_setup_request+0x225/0x3a0 [cifs] ? __pfx_cifs_compound_last_callback+0x10/0x10 [cifs] compound_send_recv+0x59b/0x1140 [cifs] ? __pfx_compound_send_recv+0x10/0x10 [cifs] ? __create_object+0x5e/0x90 ? hlock_class+0x32/0xb0 ? do_raw_spin_unlock+0x9a/0xf0 cifs_send_recv+0x23/0x30 [cifs] SMB2_tcon+0x3ec/0xb30 [cifs] ? __pfx_SMB2_tcon+0x10/0x10 [cifs] ? lock_acquire.part.0+0xf4/0x2a0 ? __pfx_lock_release+0x10/0x10 ? do_raw_spin_trylock+0xc6/0x120 ? lock_acquire+0x3f/0x90 ? _get_xid+0x16/0xd0 [cifs] ? __pfx_SMB2_tcon+0x10/0x10 [cifs] ? cifs_get_smb_ses+0xcdd/0x10a0 [cifs] cifs_get_smb_ses+0xcdd/0x10a0 [cifs] ? __pfx_cifs_get_smb_ses+0x10/0x10 [cifs] ? cifs_get_tcp_session+0xaa0/0xca0 [cifs] cifs_mount_get_session+0x8a/0x210 [cifs] dfs_mount_share+0x1b0/0x11d0 [cifs] ? __pfx___lock_acquire+0x10/0x10 ? __pfx_dfs_mount_share+0x10/0x10 [cifs] ? lock_acquire.part.0+0xf4/0x2a0 ? find_held_lock+0x8a/0xa0 ? hlock_class+0x32/0xb0 ? lock_release+0x203/0x5d0 cifs_mount+0xb3/0x3d0 [cifs] ? do_raw_spin_trylock+0xc6/0x120 ? __pfx_cifs_mount+0x10/0x10 [cifs] ? lock_acquire+0x3f/0x90 ? find_nls+0x16/0xa0 ? smb3_update_mnt_flags+0x372/0x3b0 [cifs] cifs_smb3_do_mount+0x1e2/0xc80 [cifs] ? __pfx_vfs_parse_fs_string+0x10/0x10 ? __pfx_cifs_smb3_do_mount+0x10/0x10 [cifs] smb3_get_tree+0x1bf/0x330 [cifs] vfs_get_tree+0x4a/0x160 path_mount+0x3c1/0xfb0 ? kasan_quarantine_put+0xc7/0x1d0 ? __pfx_path_mount+0x10/0x10 ? kmem_cache_free+0x118/0x3e0 ? user_path_at+0x74/0xa0 __x64_sys_mount+0x1a6/0x1e0 ? __pfx___x64_sys_mount+0x10/0x10 ? mark_held_locks+0x1a/0x90 do_syscall_64+0xbb/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f

CVE-2024-56593 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: Fix oops due to NULL pointer dereference in brcmf_sdiod_sglist_rw()This patch fixes a NULL pointer dereference bug in brcmfmac that occurswhen a high 'sd_sgentry_align' value applies (e.g. 512) and a lot of queued SKBsare sent from the pkt queue.The problem is the number of entries in the pre-allocated sgtable, it isnents = max(rxglom_size, txglom_size) + max(rxglom_size, txglom_size) >> 4 + 1.Given the default [rt]xglom_size=32 it's actually 35 which is too small.Worst case, the pkt queue can end up with 64 SKBs. This occurs when a new SKBis added for each original SKB if tailroom isn't enough to hold tail_pad.At least one sg entry is needed for each SKB. So, eventually the "skb_queue_walk loop"in brcmf_sdiod_sglist_rw may run out of sg entries. This makes sg_next returnNULL and this causes the oops.The patch sets nents to max(rxglom_size, txglom_size) * 2 to be able handlethe worst-case.Btw. this requires only 64-35=29 * 16 (or 20 if CONFIG_NEED_SG_DMA_LENGTH) = 464additional bytes of memory.

CVE-2024-56615 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 <48> 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] [ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482]

Additionally, since this system lacks swap, the calculation of inactive/active anonymous pages is skipped. crash> p nr_swap_pages nr_swap_pages = $1937 = { counter = 0 }As a result, ZONE_DMA32 is deemed unreclaimable and skipped, moving on tothe processing of the next zone, ZONE_NORMAL, despite ZONE_DMA32 havingfree pages significantly exceeding the high watermark.The problem is that the pgdat->kswapd_failures hasn't been incremented. crash> px ((struct pglist_data *) 0xffff00817fffe540)->kswapd_failures $1935 = 0x0This is because the node deemed balanced. The node balancing logic inbalance_pgdat() evaluates all zones collectively. If one or more zones(e.g., ZONE_DMA32) have enough free pages to meet their watermarks, theentire node is deemed balanced. This causes balance_pgdat() to exit earlybefore incrementing the kswapd_failures, as it considers the overallmemory state acceptable, even though some zones (like ZONE_NORMAL) remainunder significant pressure.The patch ensures that zone_reclaimable_pages() includes free pages(NR_FREE_PAGES) in its calculation when no other reclaimable pages areavailable (e.g., file-backed or anonymous pages). This change preventszones like ZONE_DMA32, which have sufficient free pages, from beingmistakenly deemed unreclaimable. By doing so, the patch ensures propernode balancing, avoids masking pressure on other zones like ZONE_NORMAL,and prevents infinite loops in throttle_direct_reclaim() caused byallow_direct_reclaim(pgdat) repeatedly returning false.The kernel hangs due to a task stuck in throttle_direct_reclaim(), causedby a node being incorrectly deemed balanced despite pressure in certainzones, such as ZONE_NORMAL. This issue arises fromzone_reclaimable_pages---truncated---

CVE-2024-57924 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:fs: relax assertions on failure to encode file handlesEncoding file handles is usually performed by a filesystem >encode_fh()method that may fail for various reasons.The legacy users of exportfs_encode_fh(), namely, nfsd andname_to_handle_at(2) syscall are ready to cope with the possibilityof failure to encode a file handle.There are a few other users of exportfs_encode_{fh,fid}() thatcurrently have a WARN_ON() assertion when ->encode_fh() fails.Relax those assertions because they are wrong.The second linked bug report states commit 16aac5ad1fa9 ("ovl: supportencoding non-decodable file handles") in v6.6 as the regressing commit,but this is not accurate.The aforementioned commit only increases the chances of the assertionand allows triggering the assertion with the reproducer using overlayfs,inotify and drop_caches.Triggering this assertion was always possible with other filesystems andother reasons of ->encode_fh() failures and more particularly, it wasalso possible with the exact same reproducer using overlayfs that ismounted with options index=on,nfs_export=on also on kernels < v6.6.Therefore, I am not listing the aforementioned commit as a Fixes commit.Backport hint: this patch will have a trivial conflict applying tov6.6.y, and other trivial conflicts applying to stable kernels < v6.6.

Description: In the Linux kernel, the following vulnerability has been resolved:gve: guard XDP xmit NDO on existence of xdp queuesIn GVE, dedicated XDP queues only exist when an XDP program is installedand the interface is up. As such, the NDO XDP XMIT callback shouldreturn early if either of these conditions are false.In the case of no loaded XDP program, priv->num_xdp_queues=0 which cancause a divide-by-zero error, and in the case of interface down,num_xdp_queues remains untouched to persist XDP queue count for the nextinterface up, but the TX pointer itself would be NULL.The XDP xmit callback also needs to synchronize with a devicetransitioning from open to close. This synchronization will happen viathe GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call,which waits for any RCU critical sections at call-time to complete.

Kernel panic - not syncing: Oops - BUG: Fatal exceptionThis happens because pps_device_destruct() frees the pps_device with theembedded cdev immediately after calling cdev_del(), but, as the commentabove cdev_del() notes, fops for previously opened cdevs are stillcallable even after cdev_del() returns. I think this bug has alwaysbeen there: I can't explain why it suddenly started happening every timeI reboot this particular board.In commit d953e0e837e6 ("pps: Fix a use-after free bug whenunregistering a source."), George Spelvin suggested removing theembedded cdev. That seems like the simplest way to fix this, so I'veimplemented his suggestion, using __register_chrdev() with pps_idrbecoming the source of truth for which minor corresponds to whichdevice.But now that pps_idr defines userspace visibility instead of cdev_add(),we need to be sure the pps->dev refcount can't reach zero whileuserspace can still find it again. So, the idr_remove() call moves topps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1

Description: In the Linux kernel, the following vulnerability has been resolved:usb: xhci: Fix NULL pointer dereference on certain command abortsIf a command is queued to the final usable TRB of a ring segment, theenqueue pointer is advanced to the subsequent link TRB and no further.If the command is later aborted, when the abort completion is handledthe dequeue pointer is advanced to the first TRB of the next segment.If no further commands are queued, xhci_handle_stopped_cmd_ring() seesthe ring pointers unequal and assumes that there is a pending command,so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbellring likely is unnecessary too, but it's harmless. Leave it alone.This is probably Bug 219532, but no confirmation has been received.The issue has been independently reproduced and confirmed fixed usinga USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.Everything continued working normally after several prevented crashes.

CVE-2024-58072 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rtlwifi: remove unused check_buddy_privCommit 2461c7d60f9f ("rtlwifi: Update header file") introduced a globallist of private data structures.Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to matchvendor version 2013.02.07") started adding the private data to that list atprobe time and added a hook, check_buddy_priv to find the private data froma similar device.However, that function was never used.Besides, though there is a lock for that list, it is never used. And whenthe probe fails, the private data is never removed from the list. Thiswould cause a second probe to access freed memory.Remove the unused hook, structures and members, which will prevent thepotential race condition on the list and its corruption during a secondprobe when probe fails.

CVE-2024-58083 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Explicitly verify target vCPU is online in kvm_get_vcpu()Explicitly verify the target vCPU is fully online _prior_ to clamping theindex in kvm_get_vcpu(). If the index is "bad", the nospec clamping willgenerate '0', i.e. KVM will return vCPU0 instead of NULL.In practice, the bug is unlikely to cause problems, as it will only comeinto play if userspace or the guest is buggy or misbehaving, e.g. KVM maysend interrupts to vCPU0 instead of dropping them on the floor.However, returning vCPU0 when it shouldn't exist per online_vcpus isproblematic now that KVM uses an xarray for the vCPUs array, as KVM needsto insert into the xarray before publishing the vCPU to userspace (seecommit c5b077549136 ("KVM: Convert the kvm->vcpus array to a xarray")),i.e. before vCPU creation is guaranteed to succeed.As a result, incorrectly providing access to vCPU0 will trigger ause-after-free if vCPU0 is dereferenced and kvm_vm_ioctl_create_vcpu()bails out of vCPU creation due to an error and frees vCPU0. Commitafb2acb2e3a3 ("KVM: Fix vcpu_array[0] races") papered over that issue, butin doing so introduced an unsolvable teardown conundrum. Preventingaccesses to vCPU0 before it's fully online will allow reverting commitafb2acb2e3a3, without re-introducing the vcpu_array[0] UAF race.

Description: In the Linux kernel, the following vulnerability has been resolved:USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()This patch addresses a null-ptr-deref in qt2_process_read_urb() due toan incorrect bounds check in the following: if (newport > serial->num_ports) { dev_err(&port->dev, "%s - port change to invalid port: %i\n", __func__, newport); break; }The condition doesn't account for the valid range of the serial->portbuffer, which is from 0 to serial->num_ports - 1. When newport is equalto serial->num_ports, the assignment of "port" in thefollowing code is out-of-bounds and NULL: serial_priv->current_port = newport; port = serial->port[serial_priv->current_port];The fix checks if newport is greater than or equal to serial->num_portsindicating it is out-of-bounds.

CVE-2025-21831 Severity: Moderate CVSS3 score: 5.5

Description: In the Linux kernel, the following vulnerability has been resolved:PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets thepolicy that all PCIe ports are allowed to use D3. When the system issuspended if the port is not power manageable by the platform and won't beused for wakeup via a PME this sets up the policy for these ports to gointo D3hot.This policy generally makes sense from an OSPM perspective but it leads toproblems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with aspecific old BIOS. This manifests as a system hang.On the affected Device + BIOS combination, add a quirk for the root port ofthe problematic controller to ensure that these root ports are not put intoD3hot at suspend.This patch is based on https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.combut with the added condition both in the documentation and in the code toapply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and onlythe affected root ports.

CVE-2026-25645 Severity: Moderate CVSS3 score: 5.5

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: Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template, potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.

CVE-2024-9681 Severity: Moderate CVSS3 score: 5.3

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.

CVE-2025-58058 Severity: Moderate CVSS3 score: 5.3

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.

CVE-2025-66471 Severity: Moderate CVSS3 score: 5.3

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.

CVE-2024-56770 Severity: Moderate CVSS3 score: 5.1

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: netem: account for backlog updates from child qdiscIn general, 'qlen' of any classful qdisc should keep track of thenumber of packets that the qdisc itself and all of its children holds.In case of netem, 'qlen' only accounts for the packets in its internaltfifo. When netem is used with a child qdisc, the child qdisc can use'qdisc_tree_reduce_backlog' to inform its parent, netem, about createdor dropped SKBs. This function updates 'qlen' and the backlog statisticsof netem, but netem does not account for changes made by a child qdisc.'qlen' then indicates the wrong number of packets in the tfifo.If a child qdisc creates new SKBs during enqueue and informs its parentabout this, netem's 'qlen' value is increased. When netem dequeues thenewly created SKBs from the child, the 'qlen' in netem is not updated.If 'qlen' reaches the configured sch->limit, the enqueue function stopsworking, even though the tfifo is not full.Reproduce the bug:Ensure that the sender machine has GSO enabled. Configure netem as rootqdisc and tbf as its child on the outgoing interface of the machineas follows:$ tc qdisc add dev root handle 1: netem delay 100ms limit 100$ tc qdisc add dev parent 1:0 tbf rate 50Mbit burst 1542 latency 50msSend bulk TCP traffic out via this interface, e.g., by running an iPerf3client on the machine. Check the qdisc statistics:$ tc -s qdisc show dev Statistics after 10s of iPerf3 TCP test before the fix (note thatnetem's backlog > limit, netem stopped accepting packets):qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0) backlog 4294528236b 1155p requeues 0qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0) backlog 0b 0p requeues 0Statistics after the fix:qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0) backlog 0b 0p requeues 0qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0) backlog 0b 0p requeues 0tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'.The interface fully stops transferring packets and "locks". In this case,the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is atits limit and no more packets are accepted.This patch adds a counter for the entries in the tfifo. Netem's 'qlen' isonly decreased when a packet is returned by its dequeue function, and notduring enqueuing into the child qdisc. External updates to 'qlen' are thusaccounted for and only the behavior of the backlog statistics changes. Asin other qdiscs, 'qlen' then keeps track of how many packets are held innetem and all of its children. As before, sch->limit remains as themaximum number of packets in the tfifo. The same applies to netem'sbacklog statistics.

Description: In the Linux kernel, the following vulnerability has been resolved:i2c: lpi2c: Avoid calling clk_get_rate during transferInstead of repeatedly calling clk_get_rate for each transfer, lockthe clock rate and cache the value.A deadlock has been observed while adding tlv320aic32x4 audio codec tothe system. When this clock provider adds its clock, the clk mutex islocked already, it needs to access i2c, which in return needs the mutexfor clk_get_rate as well.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: do not BUG_ON() when freeing tree block after errorWhen freeing a tree block, at btrfs_free_tree_block(), if we fail tocreate a delayed reference we don't deal with the error and just do aBUG_ON(). The error most likely to happen is -ENOMEM, and we have acomment mentioning that only -ENOMEM can happen, but that is not true,because in case qgroups are enabled any error returned frombtrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returnedfrom btrfs_search_slot() for example) can be propagated back tobtrfs_free_tree_block().So stop doing a BUG_ON() and return the error to the callers and makethem abort the transaction to prevent leaking space.

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

This reordering prevents the race conditionfrom happening.

CVE-2024-56700 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:media: wl128x: Fix atomicity violation in fmc_send_cmd()Atomicity violation occurs when the fmc_send_cmd() function is executedsimultaneously with the modification of the fmdev->resp_skb value.Consider a scenario where, after passing the validity check within thefunction, a non-null fmdev->resp_skb variable is assigned a null value.This results in an invalid fmdev->resp_skb variable passing the validitycheck. As seen in the later part of the function, skb = fmdev->resp_skb;when the invalid fmdev->resp_skb passes the check, a null pointerdereference error may occur at line 478, evt_hdr = (void *)skb->data;To address this issue, it is recommended to include the validity check offmdev->resp_skb within the locked section of the function. Thismodification ensures that the value of fmdev->resp_skb does not changeduring the validation process, thereby maintaining its validity.This possible bug is found by an experimental static analysis tooldeveloped by our team. This tool analyzes the locking APIsto extract function pairs that can be concurrently executed, and thenanalyzes the instructions in the paired functions to identify possibleconcurrency bugs including data races and atomicity violations.

CVE-2025-21664 Severity: Moderate CVSS3 score: 4.7

Description: In the Linux kernel, the following vulnerability has been resolved:dm thin: make get_first_thin use rcu-safe list first functionThe documentation in rculist.h explains the absence of list_empty_rcu()and cautions programmers against relying on a list_empty() ->list_first() sequence in RCU safe code. This is because each of thesefunctions performs its own READ_ONCE() of the list head. This can leadto a situation where the list_empty() sees a valid list entry, but thesubsequent list_first() sees a different view of list head state after amodification.In the case of dm-thin, this author had a production box crash from a GPfault in the process_deferred_bios path. This function saw a valid listhead in get_first_thin() but when it subsequently dereferenced that andturned it into a thin_c, it got the inside of the struct pool, since thelist was now empty and referring to itself. The kernel on which thisoccurred printed both a warning about a refcount_t being saturated, anda UBSAN error for an out-of-bounds cpuid access in the queued spinlock,prior to the fault itself. When the resulting kdump was examined, itwas possible to see another thread patiently waiting in thin_dtr'ssynchronize_rcu.The thin_dtr call managed to pull the thin_c out of the active thinslist (and have it be the last entry in the active_thins list) at justthe wrong moment which lead to this crash.Fortunately, the fix here is straight forward. Switch get_first_thin()function to use list_first_or_null_rcu() which performs just a singleREAD_ONCE() and returns NULL if the list is already empty.This was run against the devicemapper test suite's thin-provisioningsuites for delete and suspend and no regressions were observed.

Log an error and discard the notificationinstead of reading lengths from memory outside the received data, which canlead to memory corruption when the expected_size decreases betweenfragments, causing `expected_size - acm->nb_index` to wrap.This issue has been present since the beginning of git history; however,it only leads to memory corruption since commit ea2583529cd1("cdc-acm: reassemble fragmented notifications").A mitigating factor is that acm_ctrl_irq() can only execute after userspacehas opened /dev/ttyACM*; but if ModemManager is running, ModemManager willdo that automatically depending on the USB device's vendor/product IDs andits other interfaces.

CVE-2024-43790 Severity: Moderate CVSS3 score: 4.5

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.

CVE-2024-43802 Severity: Moderate CVSS3 score: 4.5

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.

CVE-2024-45306 Severity: Moderate CVSS3 score: 4.4

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.

CVE-2022-24713 Severity: Moderate CVSS3 score: 4.3

Description: regex is an implementation of regular expressions for the Rust language. The regex crate features built-in mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This guarantee is documented and it's considered part of the crate's API. Unfortunately a bug was discovered in the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing, and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade immediately to the latest version of the regex crate. Unfortunately there is no fixed set of problematic regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability. Because of this, it us not recommend to deny known problematic regexes.

CVE-2024-35221 Severity: Moderate CVSS3 score: 4.3

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.

CVE-2026-21441 Severity: Moderate CVSS3 score: 4.3

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: Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Deployment). The supported version that is affected is Java SE: 8u221; Java SE Embedded: 8u221. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data as well as unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator).

CVE-2022-48734 Severity: Moderate CVSS3 score: 4.1

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.

CVE-2024-47814 Severity: Low CVSS3 score: 3.9

Description: Vim is an open source, command line text editor. A use-after-free was found in Vim < 9.1.0764. When closing a buffer (visible in a window) a BufWinLeave auto command can cause an use-after-free if this auto command happens to re-open the same buffer in a new split window. Impact is low since the user must have intentionally set up such a strange auto command and run some buffer unload commands. However this may lead to a crash. This issue has been addressed in version 9.1.0764 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2022-49086 Severity: Moderate CVSS3 score: 3.3

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: fix leak of nested actionsWhile parsing user-provided actions, openvswitch module may dynamicallyallocate memory and store pointers in the internal copy of the actions.So this memory has to be freed while destroying the actions.Currently there are only two such actions: ct() and set(). However,there are many actions that can hold nested lists of actions andovs_nla_free_flow_actions() just jumps over them leaking the memory.For example, removal of the flow with the following actions will leadto a leak of the memory allocated by nf_ct_tmpl_alloc(): actions:clone(ct(commit),0)Non-freed set() action may also leak the 'dst' structure for thetunnel info including device references.Under certain conditions with a high rate of flow rotation that maycause significant memory leak problem (2MB per second in reporter'scase). The problem is also hard to mitigate, because the user doesn'thave direct control over the datapath flows generated by OVS.Fix that by iterating over all the nested actions and freeingeverything that needs to be freed recursively.New build time assertion should protect us from this problem if newactions will be added in the future.Unfortunately, openvswitch module doesn't use NLA_F_NESTED, so allattributes has to be explicitly checked. sample() and clone() actionsare mixing extra attributes into the user-provided action list. Thatprevents some code generalization too.

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.

CVE-2024-43374 Severity: Moderate CVSS3 score: 3.3

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.

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.

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.

While it's not freed back to system correctly whenkdump kernel is reloaded or unloaded. Then memory leak is caused. Fix itby introducing x86 specific function arch_kimage_file_post_load_cleanup(),and freeing the buffer there.And also remove the incorrect elf header buffer freeing code. Beforecalling arch specific kexec_file loading function, the image instance hasbeen initialized. So 'image->elf_headers' must be NULL. It doesn't makesense to free the elf header buffer in the place.Three different people have reported three bugs about the memory leak onx86_64 inside Redhat.
