Description: GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of "Member name contains '..'" that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain "x -> ../../../../../home/victim/.ssh" and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in which "tar xf" is run more than once (e.g., when installing a package can automatically install two dependencies that are set up as untrusted tarballs instead of official packages). NOTE: the official GNU Tar manual has an otherwise-empty directory for each "tar xf" in its Security Rules of Thumb; however, third-party advice leads users to run "tar xf" more than once into the same directory.

Description: wheel is a command line tool for manipulating Python wheel files, as defined in PEP 427. In versions 0.40.0 through 0.46.1, the unpack function is vulnerable to file permission modification through mishandling of file permissions after extraction. The logic blindly trusts the filename from the archive header for the chmod operation, even though the extraction process itself might have sanitized the path. Attackers can craft a malicious wheel file that, when unpacked, changes the permissions of critical system files (e.g., /etc/passwd, SSH keys, config files), allowing for Privilege Escalation or arbitrary code execution by modifying now-writable scripts. This issue has been fixed in version 0.46.2.

Description: Rack is a modular Ruby web server interface. Prior to version 2.2.18, Rack::QueryParser enforces its params_limit only for parameters separated by &, while still splitting on both & and ;. As a result, attackers could use ; separators to bypass the parameter count limit and submit more parameters than intended. Applications or middleware that directly invoke Rack::QueryParser with its default configuration (no explicit delimiter) could be exposed to increased CPU and memory consumption. This can be abused as a limited denial-of-service vector. This issue has been patched in version 2.2.18.

Description: Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, `Rack::Multipart::Parser` buffers the entire multipart preamble (bytes before the first boundary) in memory without any size limit. A client can send a large preamble followed by a valid boundary, causing significant memory use and potential process termination due to out-of-memory (OOM) conditions. Remote attackers can trigger large transient memory spikes by including a long preamble in multipart/form-data requests. The impact scales with allowed request sizes and concurrency, potentially causing worker crashes or severe slowdown due to garbage collection. Versions 2.2.19, 3.1.17, and 3.2.2 enforce a preamble size limit (e.g., 16 KiB) or discard preamble data entirely. Workarounds include limiting total request body size at the proxy or web server level and monitoring memory and set per-process limits to prevent OOM conditions.

Description: Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, ``Rack::Multipart::Parser` stores non-file form fields (parts without a `filename`) entirely in memory as Ruby `String` objects. A single large text field in a multipart/form-data request (hundreds of megabytes or more) can consume equivalent process memory, potentially leading to out-of-memory (OOM) conditions and denial of service (DoS). Attackers can send large non-file fields to trigger excessive memory usage. Impact scales with request size and concurrency, potentially leading to worker crashes or severe garbage-collection overhead. All Rack applications processing multipart form submissions are affected. Versions 2.2.19, 3.1.17, and 3.2.2 enforce a reasonable size cap for non-file fields (e.g., 2 MiB). Workarounds include restricting maximum request body size at the web-server or proxy layer (e.g., Nginx `client_max_body_size`) and validating and rejecting unusually large form fields at the application level.

Description: Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, `Rack::Multipart::Parser` can accumulate unbounded data when a multipart part's header block never terminates with the required blank line (`CRLFCRLF`). The parser keeps appending incoming bytes to memory without a size cap, allowing a remote attacker to exhaust memory and cause a denial of service (DoS). Attackers can send incomplete multipart headers to trigger high memory use, leading to process termination (OOM) or severe slowdown. The effect scales with request size limits and concurrency. All applications handling multipart uploads may be affected. Versions 2.2.19, 3.1.17, and 3.2.2 cap per-part header size (e.g., 64 KiB). As a workaround, restrict maximum request sizes at the proxy or web server layer (e.g., Nginx `client_max_body_size`).

Description: In the Linux kernel, the following vulnerability has been resolved:net/handshake: duplicate handshake cancellations leak socketWhen a handshake request is cancelled it is removed from thehandshake_net->hn_requests list, but it is still present in thehandshake_rhashtbl until it is destroyed.If a second cancellation request arrives for the same handshake request,then remove_pending() will return false... and assumingHANDSHAKE_F_REQ_COMPLETED isn't set in req->hr_flags, we'll continueprocessing through the out_true label, where we put another reference onthe sock and a refcount underflow occurs.This can happen for example if a handshake times out - particularly ifthe SUNRPC client sends the AUTH_TLS probe to the server but doesn'tfollow it up with the ClientHello due to a problem with tlshd. When thetimeout is hit on the server, the server will send a FIN, which triggersa cancellation request via xs_reset_transport(). When the timeout ishit on the client, another cancellation request happens viaxs_tls_handshake_sync().Add a test_and_set_bit(HANDSHAKE_F_REQ_COMPLETED) in the pending cancelpath so duplicate cancels can be detected.

Description: In the Linux kernel, the following vulnerability has been resolved:ipvs: fix ipv4 null-ptr-deref in route error pathThe IPv4 code path in __ip_vs_get_out_rt() calls dst_link_failure()without ensuring skb->dev is set, leading to a NULL pointer dereferencein fib_compute_spec_dst() when ipv4_link_failure() attempts to sendICMP destination unreachable messages.The issue emerged after commit ed0de45a1008 ("ipv4: recompile ip optionsin ipv4_link_failure") started calling __ip_options_compile() fromipv4_link_failure(). This code path eventually calls fib_compute_spec_dst()which dereferences skb->dev. An attempt was made to fix the NULL skb->devdereference in commit 0113d9c9d1cc ("ipv4: fix null-deref inipv4_link_failure"), but it only addressed the immediate dev_net(skb->dev)dereference by using a fallback device. The fix was incomplete becausefib_compute_spec_dst() later in the call chain still accesses skb->devdirectly, which remains NULL when IPVS calls dst_link_failure().The crash occurs when:1. IPVS processes a packet in NAT mode with a misconfigured destination2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route3. The error path calls dst_link_failure(skb) with skb->dev == NULL4. ipv4_link_failure() -> ipv4_send_dest_unreach() -> __ip_options_compile() -> fib_compute_spec_dst()5. fib_compute_spec_dst() dereferences NULL skb->devApply the same fix used for IPv6 in commit 326bf17ea5d4 ("ipvs: fixipv6 route unreach panic"): set skb->dev from skb_dst(skb)->dev beforecalling dst_link_failure().KASAN: null-ptr-deref in range [0x0000000000000328-0x000000000000032f]CPU: 1 PID: 12732 Comm: syz.1.3469 Not tainted 6.6.114 #2RIP: 0010:__in_dev_get_rcu include/linux/inetdevice.h:233RIP: 0010:fib_compute_spec_dst+0x17a/0x9f0 net/ipv4/fib_frontend.c:285Call Trace: spec_dst_fill net/ipv4/ip_options.c:232 spec_dst_fill net/ipv4/ip_options.c:229 __ip_options_compile+0x13a1/0x17d0 net/ipv4/ip_options.c:330 ipv4_send_dest_unreach net/ipv4/route.c:1252 ipv4_link_failure+0x702/0xb80 net/ipv4/route.c:1265 dst_link_failure include/net/dst.h:437 __ip_vs_get_out_rt+0x15fd/0x19e0 net/netfilter/ipvs/ip_vs_xmit.c:412 ip_vs_nat_xmit+0x1d8/0xc80 net/netfilter/ipvs/ip_vs_xmit.c:764

Description: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. If an application makes use of the request.read() method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g. 1 second) while processing the request. This could potentially lead to DoS as the server would be unable to handle other requests during that time. This issue is fixed in version 3.13.3.

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: BUG() in pskb_expand_head() as part of calipso_skbuff_setattr()There exists a kernel oops caused by a BUG_ON(nhead < 0) atnet/core/skbuff.c:2232 in pskb_expand_head().This bug is triggered as part of the calipso_skbuff_setattr()routine when skb_cow() is passed headroom > INT_MAX(i.e. (int)(skb_headroom(skb) + len_delta) < 0).The root cause of the bug is due to an implicit integer cast in__skb_cow(). The check (headroom > skb_headroom(skb)) is meant to ensurethat delta = headroom - skb_headroom(skb) is never negative, otherwisewe will trigger a BUG_ON in pskb_expand_head(). However, ifheadroom > INT_MAX and delta <= -NET_SKB_PAD, the check passes, deltabecomes negative, and pskb_expand_head() is passed a negative value fornhead.Fix the trigger condition in calipso_skbuff_setattr().

Description: In the Linux kernel, the following vulnerability has been resolved:usb: phy: fsl-usb: Fix use-after-free in delayed work during device removalThe delayed work item otg_event is initialized in fsl_otg_conf() andscheduled under two conditions:1. When a host controller binds to the OTG controller.2. When the USB ID pin state changes (cable insertion/removal).A race condition occurs when the device is removed via fsl_otg_remove():the fsl_otg instance may be freed while the delayed work is still pendingor executing. This leads to use-after-free when the work functionfsl_otg_event() accesses the already freed memory.The problematic scenario:(detach thread) | (delayed work)fsl_otg_remove() | kfree(fsl_otg_dev) //FREE| fsl_otg_event() | og = container_of(...) //USE | og-> //USEFix this by calling disable_delayed_work_sync() in fsl_otg_remove()before deallocating the fsl_otg structure. This ensures the delayed workis properly canceled and completes execution prior to memory deallocation.This bug was identified through static analysis.

Description: In the Linux kernel, the following vulnerability has been resolved:iommu: disable SVA when CONFIG_X86 is setPatch series "Fix stale IOTLB entries for kernel address space", v7.This proposes a fix for a security vulnerability related to IOMMU SharedVirtual Addressing (SVA). In an SVA context, an IOMMU can cache kernelpage table entries. When a kernel page table page is freed andreallocated for another purpose, the IOMMU might still hold stale,incorrect entries. This can be exploited to cause a use-after-free orwrite-after-free condition, potentially leading to privilege escalation ordata corruption.This solution introduces a deferred freeing mechanism for kernel pagetable pages, which provides a safe window to notify the IOMMU toinvalidate its caches before the page is reused.This patch (of 8):In the IOMMU Shared Virtual Addressing (SVA) context, the IOMMU hardwareshares and walks the CPU's page tables. The x86 architecture maps thekernel's virtual address space into the upper portion of every process'spage table. Consequently, in an SVA context, the IOMMU hardware can walkand cache kernel page table entries.The Linux kernel currently lacks a notification mechanism for kernel pagetable changes, specifically when page table pages are freed and reused. The IOMMU driver is only notified of changes to user virtual addressmappings. This can cause the IOMMU's internal caches to retain staleentries for kernel VA.Use-After-Free (UAF) and Write-After-Free (WAF) conditions arise whenkernel page table pages are freed and later reallocated. The IOMMU couldmisinterpret the new data as valid page table entries. The IOMMU mightthen walk into attacker-controlled memory, leading to arbitrary physicalmemory DMA access or privilege escalation. This is also aWrite-After-Free issue, as the IOMMU will potentially continue to writeAccessed and Dirty bits to the freed memory while attempting to walk thestale page tables.Currently, SVA contexts are unprivileged and cannot access kernelmappings. However, the IOMMU will still walk kernel-only page tables allthe way down to the leaf entries, where it realizes the mapping is for thekernel and errors out. This means the IOMMU still caches theseintermediate page table entries, making the described vulnerability a realconcern.Disable SVA on x86 architecture until the IOMMU can receive notificationto flush the paging cache before freeing the CPU kernel page table pages.

Description: In the Linux kernel, the following vulnerability has been resolved:erspan: Initialize options_len before referencing options.The struct ip_tunnel_info has a flexible array member namedoptions that is protected by a counted_by(options_len)attribute.The compiler will use this information to enforce runtime boundschecking deployed by FORTIFY_SOURCE string helpers.As laid out in the GCC documentation, the counter must beinitialized before the first reference to the flexible arraymember.After scanning through the files that use struct ip_tunnel_infoand also refer to options or options_len, it appears the normalcase is to use the ip_tunnel_info_opts_set() helper.Said helper would initialize options_len properly before copyingdata into options, however in the GRE ERSPAN code a partialupdate is done, preventing the use of the helper function.Before this change the handling of ERSPAN traffic in GRE tunnelswould cause a kernel panic when the kernel is compiled withGCC 15+ and having FORTIFY_SOURCE configured:memcpy: detected buffer overflow: 4 byte write of buffer size 0Call Trace: __fortify_panic+0xd/0xf erspan_rcv.cold+0x68/0x83 ? ip_route_input_slow+0x816/0x9d0 gre_rcv+0x1b2/0x1c0 gre_rcv+0x8e/0x100 ? raw_v4_input+0x2a0/0x2b0 ip_protocol_deliver_rcu+0x1ea/0x210 ip_local_deliver_finish+0x86/0x110 ip_local_deliver+0x65/0x110 ? ip_rcv_finish_core+0xd6/0x360 ip_rcv+0x186/0x1a0Reported-at: https://launchpad.net/bugs/2129580

Description: In the Linux kernel, the following vulnerability has been resolved:mlxsw: spectrum_router: Fix neighbour use-after-freeWe sometimes observe use-after-free when dereferencing a neighbour [1].The problem seems to be that the driver stores a pointer to theneighbour, but without holding a reference on it. A reference is onlytaken when the neighbour is used by a nexthop.Fix by simplifying the reference counting scheme. Always take areference when storing a neighbour pointer in a neighbour entry. Avoidtaking a referencing when the neighbour is used by a nexthop as theneighbour entry associated with the nexthop already holds a reference.Tested by running the test that uncovered the problem over 300 times.Without this patch the problem was reproduced after a handful ofiterations.[1]BUG: KASAN: slab-use-after-free in mlxsw_sp_neigh_entry_update+0x2d4/0x310Read of size 8 at addr ffff88817f8e3420 by task ip/3929CPU: 3 UID: 0 PID: 3929 Comm: ip Not tainted 6.18.0-rc4-virtme-g36b21a067510 #3 PREEMPT(full)Hardware name: Nvidia SN5600/VMOD0013, BIOS 5.13 05/31/2023Call Trace: dump_stack_lvl+0x6f/0xa0 print_address_description.constprop.0+0x6e/0x300 print_report+0xfc/0x1fb kasan_report+0xe4/0x110 mlxsw_sp_neigh_entry_update+0x2d4/0x310 mlxsw_sp_router_rif_gone_sync+0x35f/0x510 mlxsw_sp_rif_destroy+0x1ea/0x730 mlxsw_sp_inetaddr_port_vlan_event+0xa1/0x1b0 __mlxsw_sp_inetaddr_lag_event+0xcc/0x130 __mlxsw_sp_inetaddr_event+0xf5/0x3c0 mlxsw_sp_router_netdevice_event+0x1015/0x1580 notifier_call_chain+0xcc/0x150 call_netdevice_notifiers_info+0x7e/0x100 __netdev_upper_dev_unlink+0x10b/0x210 netdev_upper_dev_unlink+0x79/0xa0 vrf_del_slave+0x18/0x50 do_set_master+0x146/0x7d0 do_setlink.isra.0+0x9a0/0x2880 rtnl_newlink+0x637/0xb20 rtnetlink_rcv_msg+0x6fe/0xb90 netlink_rcv_skb+0x123/0x380 netlink_unicast+0x4a3/0x770 netlink_sendmsg+0x75b/0xc90 __sock_sendmsg+0xbe/0x160 ____sys_sendmsg+0x5b2/0x7d0 ___sys_sendmsg+0xfd/0x180 __sys_sendmsg+0x124/0x1c0 do_syscall_64+0xbb/0xfd0 entry_SYSCALL_64_after_hwframe+0x4b/0x53[...]Allocated by task 109: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7b/0x90 __kmalloc_noprof+0x2c1/0x790 neigh_alloc+0x6af/0x8f0 ___neigh_create+0x63/0xe90 mlxsw_sp_nexthop_neigh_init+0x430/0x7e0 mlxsw_sp_nexthop_type_init+0x212/0x960 mlxsw_sp_nexthop6_group_info_init.constprop.0+0x81f/0x1280 mlxsw_sp_nexthop6_group_get+0x392/0x6a0 mlxsw_sp_fib6_entry_create+0x46a/0xfd0 mlxsw_sp_router_fib6_replace+0x1ed/0x5f0 mlxsw_sp_router_fib6_event_work+0x10a/0x2a0 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20Freed by task 154: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_save_free_info+0x3b/0x60 __kasan_slab_free+0x43/0x70 kmem_cache_free_bulk.part.0+0x1eb/0x5e0 kvfree_rcu_bulk+0x1f2/0x260 kfree_rcu_work+0x130/0x1b0 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20Last potentially related work creation: kasan_save_stack+0x30/0x50 kasan_record_aux_stack+0x8c/0xa0 kvfree_call_rcu+0x93/0x5b0 mlxsw_sp_router_neigh_event_work+0x67d/0x860 process_one_work+0xd57/0x1390 worker_thread+0x4d6/0xd40 kthread+0x355/0x5b0 ret_from_fork+0x1d4/0x270 ret_from_fork_asm+0x11/0x20

Description: In the Linux kernel, the following vulnerability has been resolved:crypto: af_alg - zero initialize memory allocated via sock_kmallocSeveral crypto user API contexts and requests allocated withsock_kmalloc() were left uninitialized, relying on callers toset fields explicitly. This resulted in the use of uninitializeddata in certain error paths or when new fields are added in thefuture.The ACVP patches also contain two user-space interface files:algif_kpp.c and algif_akcipher.c. These too rely on properinitialization of their context structures.A particular issue has been observed with the newly added'inflight' variable introduced in af_alg_ctx by commit: 67b164a871af ("crypto: af_alg - Disallow multiple in-flight AIO requests")Because the context is not memset to zero after allocation,the inflight variable has contained garbage values. As a result,af_alg_alloc_areq() has incorrectly returned -EBUSY randomly whenthe garbage value was interpreted as true: https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209The check directly tests ctx->inflight without explicitlycomparing against true/false. Since inflight is only ever set totrue or false later, an uninitialized value has triggered-EBUSY failures. Zero-initializing memory allocated withsock_kmalloc() ensures inflight and other fields start in a knownstate, removing random issues caused by uninitialized data.

Description: In the Linux kernel, the following vulnerability has been resolved:can: kvaser_pciefd: refine error prone echo_skb_max handling logicecho_skb_max should define the supported upper limit of echo_skb[]allocated inside the netdevice's priv. The corresponding size valueprovided by this driver to alloc_candev() is KVASER_PCIEFD_CAN_TX_MAX_COUNTwhich is 17.But later echo_skb_max is rounded up to the nearest power of two (for themax case, that would be 32) and the tx/ack indices calculated furtherduring tx/rx may exceed the upper array boundary. Kasan reported this forthe ack case inside kvaser_pciefd_handle_ack_packet(), though the xmitfunction has actually caught the same thing earlier.

Description: In the Linux kernel, the following vulnerability has been resolved:RDMA/core: Check for the presence of LS_NLA_TYPE_DGID correctlyThe netlink response for RDMA_NL_LS_OP_IP_RESOLVE should always have aLS_NLA_TYPE_DGID attribute, it is invalid if it does not.Use the nl parsing logic properly and call nla_parse_deprecated() to fillthe nlattrs array and then directly index that array to get the data forthe DGID. Just fail if it is NULL.Remove the for loop searching for the nla, and squash the validation andparsing into one function.Fixes an uninitialized read from the stack triggered by userspace if itdoes not provide the DGID to a kernel initiated RDMA_NL_LS_OP_IP_RESOLVEquery.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timerWhen advancing the target expiration for the guest's APIC timer in periodicmode, set the expiration to "now" if the target expiration is in the past(similar to what is done in update_target_expiration()). Blindly addingthe period to the previous target expiration can result in KVM generatinga practically unbounded number of hrtimer IRQs due to programming anexpired timer over and over. In extreme scenarios, e.g. if userspacepauses/suspends a VM for an extended duration, this can even cause hardlockups in the host.Currently, the bug only affects Intel CPUs when using the hypervisor timer(HV timer), a.k.a. the VMX preemption timer. Unlike the software timer,a.k.a. hrtimer, which KVM keeps running even on exits to userspace, theHV timer only runs while the guest is active. As a result, if the vCPUdoes not run for an extended duration, there will be a huge gap betweenthe target expiration and the current time the vCPU resumes running.Because the target expiration is incremented by only one period on eachtimer expiration, this leads to a series of timer expirations occurringrapidly after the vCPU/VM resumes.More critically, when the vCPU first triggers a periodic HV timerexpiration after resuming, advancing the expiration by only one periodwill result in a target expiration in the past. As a result, the deltamay be calculated as a negative value. When the delta is converted intoan absolute value (tscdeadline is an unsigned u64), the resulting valuecan overflow what the HV timer is capable of programming. I.e. the largevalue will exceed the VMX Preemption Timer's maximum bit width ofcpu_preemption_timer_multi + 32, and thus cause KVM to switch from theHV timer to the software timer (hrtimers).After switching to the software timer, periodic timer expiration callbacksmay be executed consecutively within a single clock interrupt handler,because hrtimers honors KVM's request for an expiration in the past andimmediately re-invokes KVM's callback after reprogramming. And becausethe interrupt handler runs with IRQs disabled, restarting KVM's hrtimerover and over until the target expiration is advanced to "now" can resultin a hard lockup.E.g. the following hard lockup was triggered in the host when running aWindows VM (only relevant because it used the APIC timer in periodic mode)after resuming the VM from a long suspend (in the host).

Since the periodic timer does not require frequent APICtimer register programming, the guest may continue to use the softwaretimer in ---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:dst: fix races in rt6_uncached_list_del() and rt_del_uncached_list()syzbot was able to crash the kernel in rt6_uncached_list_flush_dev()in an interesting way [1]Crash happens in list_del_init()/INIT_LIST_HEAD() while writinglist->prev, while the prior write on list->next went well.static inline void INIT_LIST_HEAD(struct list_head *list){ WRITE_ONCE(list->next, list); // This went well WRITE_ONCE(list->prev, list); // Crash, @list has been freed.}Issue here is that rt6_uncached_list_del() did not attempt to lockul->lock, as list_empty(&rt->dst.rt_uncached) returnedtrue because the WRITE_ONCE(list->next, list) happened on the other CPU.We might use list_del_init_careful() and list_empty_careful(),or make sure rt6_uncached_list_del() always grabs the spinlockwhenever rt->dst.rt_uncached_list has been set.A similar fix is neeed for IPv4.[1] BUG: KASAN: slab-use-after-free in INIT_LIST_HEAD include/linux/list.h:46 [inline] BUG: KASAN: slab-use-after-free in list_del_init include/linux/list.h:296 [inline] BUG: KASAN: slab-use-after-free in rt6_uncached_list_flush_dev net/ipv6/route.c:191 [inline] BUG: KASAN: slab-use-after-free in rt6_disable_ip+0x633/0x730 net/ipv6/route.c:5020Write of size 8 at addr ffff8880294cfa78 by task kworker/u8:14/3450CPU: 0 UID: 0 PID: 3450 Comm: kworker/u8:14 Tainted: G L syzkaller #0 PREEMPT_{RT,(full)}Tainted: [L]=SOFTLOCKUPHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/25/2025Workqueue: netns cleanup_netCall Trace: dump_stack_lvl+0xe8/0x150 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0xca/0x240 mm/kasan/report.c:482 kasan_report+0x118/0x150 mm/kasan/report.c:595 INIT_LIST_HEAD include/linux/list.h:46 [inline] list_del_init include/linux/list.h:296 [inline] rt6_uncached_list_flush_dev net/ipv6/route.c:191 [inline] rt6_disable_ip+0x633/0x730 net/ipv6/route.c:5020 addrconf_ifdown+0x143/0x18a0 net/ipv6/addrconf.c:3853 addrconf_notify+0x1bc/0x1050 net/ipv6/addrconf.c:-1 notifier_call_chain+0x19d/0x3a0 kernel/notifier.c:85 call_netdevice_notifiers_extack net/core/dev.c:2268 [inline] call_netdevice_notifiers net/core/dev.c:2282 [inline] netif_close_many+0x29c/0x410 net/core/dev.c:1785 unregister_netdevice_many_notify+0xb50/0x2330 net/core/dev.c:12353 ops_exit_rtnl_list net/core/net_namespace.c:187 [inline] ops_undo_list+0x3dc/0x990 net/core/net_namespace.c:248 cleanup_net+0x4de/0x7b0 net/core/net_namespace.c:696 process_one_work kernel/workqueue.c:3257 [inline] process_scheduled_works+0xad1/0x1770 kernel/workqueue.c:3340 worker_thread+0x8a0/0xda0 kernel/workqueue.c:3421 kthread+0x711/0x8a0 kernel/kthread.c:463 ret_from_fork+0x510/0xa50 arch/x86/kernel/process.c:158 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:246 Allocated by task 803: kasan_save_stack mm/kasan/common.c:57 [inline] kasan_save_track+0x3e/0x80 mm/kasan/common.c:78 unpoison_slab_object mm/kasan/common.c:340 [inline] __kasan_slab_alloc+0x6c/0x80 mm/kasan/common.c:366 kasan_slab_alloc include/linux/kasan.h:253 [inline] slab_post_alloc_hook mm/slub.c:4953 [inline] slab_alloc_node mm/slub.c:5263 [inline] kmem_cache_alloc_noprof+0x18d/0x6c0 mm/slub.c:5270 dst_alloc+0x105/0x170 net/core/dst.c:89 ip6_dst_alloc net/ipv6/route.c:342 [inline] icmp6_dst_alloc+0x75/0x460 net/ipv6/route.c:3333 mld_sendpack+0x683/0xe60 net/ipv6/mcast.c:1844 mld_send_cr net/ipv6/mcast.c:2154 [inline] mld_ifc_work+0x83e/0xd60 net/ipv6/mcast.c:2693 process_one_work kernel/workqueue.c:3257 [inline] process_scheduled_works+0xad1/0x1770 kernel/workqueue.c:3340 worker_thread+0x8a0/0xda0 kernel/workqueue.c:3421 kthread+0x711/0x8a0 kernel/kthread.c:463 ret_from_fork+0x510/0xa50 arch/x86/kernel/process.c:158 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entr---truncated---

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

Description: In the Linux kernel, the following vulnerability has been resolved:iomap: adjust read range correctly for non-block-aligned positionsiomap_adjust_read_range() assumes that the position and length passed inare block-aligned. This is not always the case however, as shown in thesyzbot generated case for erofs. This causes too many bytes to beskipped for uptodate blocks, which results in returning the incorrectposition and length to read in. If all the blocks are uptodate, thisunderflows length and returns a position beyond the folio.Fix the calculation to also take into account the block offset whencalculating how many bytes can be skipped for uptodate blocks.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: target: target_core_configfs: Add length check to avoid buffer overflowA buffer overflow arises from the usage of snprintf to write into thebuffer "buf" in target_lu_gp_members_show function located in/drivers/target/target_core_configfs.c. This buffer is allocated withsize LU_GROUP_NAME_BUF (256 bytes).snprintf(...) formats multiple strings into buf with the HBA name(hba->hba_group.cg_item), a slash character, a devicename (dev->dev_group.cg_item) and a newline character, the total formatted stringlength may exceed the buffer size of 256 bytes.Since snprintf() returns the total number of bytes that would have beenwritten (the length of %s/%sn ), this value may exceed the buffer length(256 bytes) passed to memcpy(), this will ultimately cause functionmemcpy reporting a buffer overflow error.An additional check of the return value of snprintf() can avoid thisbuffer overflow.

Description: In the Linux kernel, the following vulnerability has been resolved:can: gs_usb: gs_usb_receive_bulk_callback(): check actual_length before accessing headerThe driver expects to receive a struct gs_host_frame ings_usb_receive_bulk_callback().Use struct_group to describe the header of the struct gs_host_frame andcheck that we have at least received the header before accessing anymembers of it.To resubmit the URB, do not dereference the pointer chain"dev->parent->hf_size_rx" but use "parent->hf_size_rx" instead. Since"urb->context" contains "parent", it is always defined, while "dev" is notdefined if the URB it too short.

Description: In the Linux kernel, the following vulnerability has been resolved:via_wdt: fix critical boot hang due to unnamed resource allocationThe VIA watchdog driver uses allocate_resource() to reserve a MMIOregion for the watchdog control register. However, the allocatedresource was not given a name, which causes the kernel resource treeto contain an entry marked as "" under /proc/iomem on x86platforms.During boot, this unnamed resource can lead to a critical hang becausesubsequent resource lookups and conflict checks fail to handle theinvalid entry properly.

TCP allocates an skb using alloc_skb_fclone() (from skbuff_fclone_cache) [1]2. The skb is cloned via skb_clone() using the pre-allocated fclone[3] 3. The cloned skb is queued to sk_error_queue for timestampreporting 4.

Per Intel's SDM,XSAVE saves XSTATE_BV as '0' for components that are disabled via XFD(and non-compacted XSAVE saves the initial configuration of the statecomponent): If XSAVE, XSAVEC, XSAVEOPT, or XSAVES is saving the state component i, the instruction does not generate #NM when XCR0[i] = IA32_XFD[i] = 1; instead, it operates as if XINUSE[i] = 0 (and the state component was in its initial state): it saves bit i of XSTATE_BV field of the XSAVE header as 0; in addition, XSAVE saves the initial configuration of the state component (the other instructions do not save state component i).Alternatively, KVM could always do XRSTOR with XFD=0, e.g. by usinga constant XFD based on the set of enabled features when XSAVEing fora struct fpu_guest. However, having XSTATE_BV[i]=1 for XFD-disabledfeatures can only happen in the above interrupt case, or in similarscenarios involving preemption on preemptible kernels, becausefpu_swap_kvm_fpstate()'s call to save_fpregs_to_fpstate() saves theoutgoing FPU state with the current XFD; and that is (on all but thefirst WRMSR to XFD) the guest XFD.Therefore, XFD can only go out of sync with XSTATE_BV in the aboveinterrupt case, or in similar scenarios involving preemption onpreemptible kernels, and it we can consider it (de facto) part of KVMABI that KVM_GET_XSAVE returns XSTATE_BV[i]=0 for XFD-disabled features.[Move clea---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Fix improper freeing of purex itemIn qla2xxx_process_purls_iocb(), an item is allocated viaqla27xx_copy_multiple_pkt(), which internally callsqla24xx_alloc_purex_item().The qla24xx_alloc_purex_item() function may return a pre-allocated itemfrom a per-adapter pool for small allocations, instead of dynamicallyallocating memory with kzalloc().An error handling path in qla2xxx_process_purls_iocb() incorrectly useskfree() to release the item. If the item was from the pre-allocatedpool, calling kfree() on it is a bug that can lead to memory corruption.Fix this by using the correct deallocation function,qla24xx_free_purex_item(), which properly handles both dynamicallyallocated and pre-allocated items.

Starting in version 3.1.0 and prior to versions 6.1.7.9, 7.0.8.5, 7.1.4.1, and 7.2.1.1, there is a possible ReDoS vulnerability in the query parameter filtering routines of Action Dispatch. Carefully crafted query parameters can cause query parameter filtering to take an unexpected amount of time, possibly resulting in a DoS vulnerability. All users running an affected release should either upgrade to version 6.1.7.9, 7.0.8.5, 7.1.4.1, or 7.2.1.1 or apply the relevant patch immediately. One may use Ruby 3.2 as a workaround. Ruby 3.2 has mitigations for this problem, so Rails applications using Ruby 3.2 or newer are unaffected. Rails 8.0.0.beta1 depends on Ruby 3.2 or greater so is unaffected.

Description: In the Linux kernel, the following vulnerability has been resolved:inet: frags: flush pending skbs in fqdir_pre_exit()We have been seeing occasional deadlocks on pernet_ops_rwsem sinceSeptember in NIPA. The stuck task was usually modprobe (often loadinga driver like ipvlan), trying to take the lock as a Writer.lockdep does not track readers for rwsems so the read wasn't obviousfrom the reports.On closer inspection the Reader holding the lock was conntrack loopingforever in nf_conntrack_cleanup_net_list(). Based on past experiencewith occasional NIPA crashes I looked thru the tests which run beforethe crash and noticed that the crash follows ip_defrag.sh. An immediatered flag. Scouring thru (de)fragmentation queues reveals skbs sittingaround, holding conntrack references.The problem is that since conntrack depends on nf_defrag_ipv6,nf_defrag_ipv6 will load first. Since nf_defrag_ipv6 loads first itsnetns exit hooks run _after_ conntrack's netns exit hook.Flush all fragment queue SKBs during fqdir_pre_exit() to releaseconntrack references before conntrack cleanup runs. Also flushthe queues in timer expiry handlers when they discover fqdir->deadis set, in case packet sneaks in while we're running the pre_exitflush.The commit under Fixes is not exactly the culprit, but I thinkpreviously the timer firing would eventually unblock the spinningconntrack.

Description: In the Linux kernel, the following vulnerability has been resolved:bnxt_en: Fix XDP_TX pathFor XDP_TX action in bnxt_rx_xdp(), clearing of the event flags is notcorrect. __bnxt_poll_work() -> bnxt_rx_pkt() -> bnxt_rx_xdp() may belooping within NAPI and some event flags may be set in earlieriterations. In particular, if BNXT_TX_EVENT is set earlier indicatingsome XDP_TX packets are ready and pending, it will be cleared if it isXDP_TX action again. Normally, we will set BNXT_TX_EVENT again when wesuccessfully call __bnxt_xmit_xdp(). But if the TX ring has no moreroom, the flag will not be set. This will cause the TX producer to beahead but the driver will not hit the TX doorbell.For multi-buf XDP_TX, there is no need to clear the event flags and setBNXT_AGG_EVENT. The BNXT_AGG_EVENT flag should have been set earlier inbnxt_rx_pkt().The visible symptom of this is that the RX ring associated with theTX XDP ring will eventually become empty and all packets will be dropped.Because this condition will cause the driver to not refill the RX ringseeing that the TX ring has forever pending XDP_TX packets.The fix is to only clear BNXT_RX_EVENT when we have successfullycalled __bnxt_xmit_xdp().

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

[1] is required as a dependence: it was not explicitly marked asa fix, but it is one and it has already been backported before [3]. Inother words, this commit should be backported up to [3], including [2]and [1] if that's not already there.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: ipc: fix use-after-free in ipc_msg_send_requestipc_msg_send_request() waits for a generic netlink reply using anipc_msg_table_entry on the stack. The generic netlink handler(handle_generic_event()/handle_response()) fills entry->response underipc_msg_table_lock, but ipc_msg_send_request() used to validate and freeentry->response without holding the same lock.Under high concurrency this allows a race where handle_response() iscopying data into entry->response while ipc_msg_send_request() has justfreed it, leading to a slab-use-after-free reported by KASAN inhandle_generic_event(): BUG: KASAN: slab-use-after-free in handle_generic_event+0x3c4/0x5f0 [ksmbd] Write of size 12 at addr ffff888198ee6e20 by task pool/109349 ...

Description: In the Linux kernel, the following vulnerability has been resolved:ethtool: Avoid overflowing userspace buffer on stats queryThe ethtool -S command operates across three ioctl calls:ETHTOOL_GSSET_INFO for the size, ETHTOOL_GSTRINGS for the names, andETHTOOL_GSTATS for the values.If the number of stats changes between these calls (e.g., due to devicereconfiguration), userspace's buffer allocation will be incorrect,potentially leading to buffer overflow.Drivers are generally expected to maintain stable stat counts, but somedrivers (e.g., mlx5, bnx2x, bna, ksz884x) use dynamic counters, makingthis scenario possible.Some drivers try to handle this internally:- bnad_get_ethtool_stats() returns early in case stats.n_stats is not equal to the driver's stats count.- micrel/ksz884x also makes sure not to write anything beyond stats.n_stats and overflow the buffer.However, both use stats.n_stats which is already assigned with the valuereturned from get_sset_count(), hence won't solve the issue describedhere.Change ethtool_get_strings(), ethtool_get_stats(),ethtool_get_phy_stats() to not return anything in case of a mismatchbetween userspace's size and get_sset_size(), to prevent bufferoverflow.The returned n_stats value will be equal to zero, to reflect thatnothing has been returned.This could result in one of two cases when using upstream ethtool,depending on when the size change is detected:1. When detected in ethtool_get_strings(): # ethtool -S eth2 no stats available2. When detected in get stats, all stats will be reported as zero.Both cases are presumably transient, and a subsequent ethtool callshould succeed.Other than the overflow avoidance, these two cases are very evident (nooutput/cleared stats), which is arguably better than presentingincorrect/shifted stats.I also considered returning an error instead of a "silent" response, butthat seems more destructive towards userspace apps.Notes:- This patch does not claim to fix the inherent race, it only makes sure that we do not overflow the userspace buffer, and makes for a more predictable behavior.- RTNL lock is held during each ioctl, the race window exists between the separate ioctl calls when the lock is released.- Userspace ethtool always fills stats.n_stats, but it is likely that these stats ioctls are implemented in other userspace applications which might not fill it. The added code checks that it's not zero, to prevent any regressions.

Description: In the Linux kernel, the following vulnerability has been resolved:landlock: Fix handling of disconnected directoriesDisconnected files or directories can appear when they are visible andopened from a bind mount, but have been renamed or moved from the sourceof the bind mount in a way that makes them inaccessible from the mountpoint (i.e. out of scope).Previously, access rights tied to files or directories opened through adisconnected directory were collected by walking the related hierarchydown to the root of the filesystem, without taking into account themount point because it couldn't be found. This could lead toinconsistent access results, potential access right widening, andhard-to-debug renames, especially since such paths cannot be printed.For a sandboxed task to create a disconnected directory, it needs tohave write access (i.e. FS_MAKE_REG, FS_REMOVE_FILE, and FS_REFER) tothe underlying source of the bind mount, and read access to the relatedmount point. Because a sandboxed task cannot acquire more accessrights than those defined by its Landlock domain, this could lead toinconsistent access rights due to missing permissions that should beinherited from the mount point hierarchy, while inheriting permissionsfrom the filesystem hierarchy hidden by this mount point instead.Landlock now handles files and directories opened from disconnecteddirectories by taking into account the filesystem hierarchy when themount point is not found in the hierarchy walk, and also always takinginto account the mount point from which these disconnected directorieswere opened. This ensures that a rename is not allowed if it wouldwiden access rights [1].The rationale is that, even if disconnected hierarchies might not bevisible or accessible to a sandboxed task, relying on the collectedaccess rights from them improves the guarantee that access rights willnot be widened during a rename because of the access right comparisonbetween the source and the destination (see LANDLOCK_ACCESS_FS_REFER).It may look like this would grant more access on disconnected files anddirectories, but the security policies are always enforced for all theevaluated hierarchies. This new behavior should be less surprising tousers and safer from an access control perspective.Remove a wrong WARN_ON_ONCE() canary in collect_domain_accesses() andfix the related comment.Because opened files have their access rights stored in the related filesecurity properties, there is no impact for disconnected or unlinkedfiles.

Therefore, using `<=`accesses one element past the end.Fix the issues by using `<` instead of `<=`, ensuring we do not exceedthe bounds.[1] KASAN splat about rss_key_size off-by-one BUG: KASAN: slab-out-of-bounds in iavf_config_rss+0x619/0x800 Read of size 4 at addr ffff888102c50134 by task kworker/u8:6/63 CPU: 0 UID: 0 PID: 63 Comm: kworker/u8:6 Not tainted 6.18.0-rc2-enjuk-tnguy-00378-g3005f5b77652-dirty #156 PREEMPT(voluntary) Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 Workqueue: iavf iavf_watchdog_task Call Trace: dump_stack_lvl+0x6f/0xb0 print_report+0x170/0x4f3 kasan_report+0xe1/0x1a0 iavf_config_rss+0x619/0x800 iavf_watchdog_task+0x2be7/0x3230 process_one_work+0x7fd/0x1420 worker_thread+0x4d1/0xd40 kthread+0x344/0x660 ret_from_fork+0x249/0x320 ret_from_fork_asm+0x1a/0x30 Allocated by task 63: kasan_save_stack+0x30/0x50 kasan_save_track+0x14/0x30 __kasan_kmalloc+0x7f/0x90 __kmalloc_noprof+0x246/0x6f0 iavf_watchdog_task+0x28fc/0x3230 process_one_work+0x7fd/0x1420 worker_thread+0x4d1/0xd40 kthread+0x344/0x660 ret_from_fork+0x249/0x320 ret_from_fork_asm+0x1a/0x30 The buggy address belongs to the object at ffff888102c50100 which belongs to the cache kmalloc-64 of size 64 The buggy address is located 0 bytes to the right of allocated 52-byte region [ffff888102c50100, ffff888102c50134) The buggy address belongs to the physical page: page: refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0x102c50 flags: 0x200000000000000(node=0|zone=2) page_type: f5(slab) raw: 0200000000000000 ffff8881000418c0 dead000000000122 0000000000000000 raw: 0000000000000000 0000000080200020 00000000f5000000 0000000000000000 page dumped because: kasan: bad access detected Memory state around the buggy address: ffff888102c50000: 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc fc ffff888102c50080: 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc fc >ffff888102c50100: 00 00 00 00 00 00 04 fc fc fc fc fc fc fc fc fc ^ ffff888102c50180: 00 00 00 00 00 00 00 00 fc fc fc fc fc fc fc fc ffff888102c50200: fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc fc

As for now, the maximal read size for kvec iter isonly limited by fc->max_read. For virtio-fs, max_read is UINT_MAX, sofuse_direct_io() doesn't split the 10MB buffer. It saves the address andthe size of the 10MB-sized buffer in out_args[0] of a fuse request andpasses the fuse request to virtio_fs_wake_pending_and_unlock().4) virtio_fs_wake_pending_and_unlock() uses virtio_fs_enqueue_req() toqueue the request. Because virtiofs need DMA-able address, sovirtio_fs_enqueue_req() uses kmalloc() to allocate a bounce buffer forall fuse args, copies these args into the bounce buffer and passed thephysical address of the bounce buffer to virtiofsd. The total length ofthese fuse args for the passed fuse request is about 10MB, socopy_args_to_argbuf() invokes kmalloc() with a 10MB size parameter andit triggers the warning in __alloc_pages(): if (WARN_ON_ONCE_GFP(order > MAX_PAGE_ORDER, gfp)) return NULL;5) virtio_fs_enqueue_req() will retry the memory allocation in akworker, but it won't help, because kmalloc() will always return NULLdue to the abnormal size and finit_module() will hang forever.A feasible solution is to limit the value of max_read for virtio-fs, sothe length passed to kmalloc() will be limited. However it will affectthe maximal read size for normal read. And for virtio-fs write initiatedfrom kernel, it has the similar problem but now there is no way to limitfc->max_write in kernel.So instead of limiting both the values of max_read and max_write inkernel, introducing use_pages_for_kvec_io in fuse_conn and setting it astrue in virtiofs. When use_pages_for_kvec_io is enabled, fuse will usepages instead of pointer to pass the KVEC_IO data.After switching to pages for KVEC_IO data, these pages will be used forDMA through virtio-fs. If these pages are backed by vmalloc(),{flush|invalidate}_kernel_vmap_range() are necessary to flush orinvalidate the cache before the DMA operation. So add two new fields infuse_args_pages to record the base address of vmalloc area and thecondition indicating whether invalidation is needed. Perform the flushin fuse_get_user_pages() for write operations and the invalidation infuse_release_user_pages() for read operations.It may seem necessary to introduce another fie---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:ftrace: Also allocate and copy hash for reading of filter filesCurrently the reader of set_ftrace_filter and set_ftrace_notrace just addsthe pointer to the global tracer hash to its iterator. Unlike the writerthat allocates a copy of the hash, the reader keeps the pointer to thefilter hashes. This is problematic because this pointer is static acrossfunction calls that release the locks that can update the global tracerhashes. This can cause UAF and similar bugs.Allocate and copy the hash for reading the filter files like it is donefor the writers. This not only fixes UAF bugs, but also makes the code abit simpler as it doesn't have to differentiate when to free theiterator's hash between writers and readers.

Itwill call the count_max_entries() to find in an out-of-order date whichcounting algorithm has O(n^2) complexity.To make it faster, we sort the relocation list by info and addend. Thatway, to check for a duplicate relocation, it just needs to compare withthe previous entry. This reduces the complexity of the algorithm to O(n log n), as done in commit d4e0340919fb ("arm64/module: Optimize moduleload time by optimizing PLT counting"). This gives sinificant reductionin module load time for modules with large number of relocations.After applying this patch, the soft deadlock problem has been solved,and the kernel starts normally without "Call Trace".Using the default configuration to test some modules, the results are asfollows:Module Sizeip_tables 36Kfat 143Kradeon 2.5MBamdgpu 16MBWithout this patch:Module Module load time (ms) Count(PLTs/GOTs)ip_tables 18 59/6fat 0 162/14radeon 54 1221/84amdgpu 1411 4525/1098With this patch:Module Module load time (ms) Count(PLTs/GOTs)ip_tables 18 59/6fat 0 162/14radeon 22 1221/84amdgpu 45 4525/1098

Description: In the Linux kernel, the following vulnerability has been resolved:mm/debug_vm_pgtable: clear page table entries at destroy_args()The mm/debug_vm_pagetable test allocates manually page table entries forthe tests it runs, using also its manually allocated mm_struct. That initself is ok, but when it exits, at destroy_args() it fails to clear thoseentries with the *_clear functions.The problem is that leaves stale entries. If another process allocates anmm_struct with a pgd at the same address, it may end up running into thestale entry. This is happening in practice on a debug kernel withCONFIG_DEBUG_VM_PGTABLE=y, for example this is the output with some extradebugging I added (it prints a warning trace if pgtables_bytes goesnegative, in addition to the warning at check_mm() function):[ 2.539353] debug_vm_pgtable: [get_random_vaddr ]: random_vaddr is 0x7ea247140000[ 2.539366] kmem_cache info[ 2.539374] kmem_cachep 0x000000002ce82385 - freelist 0x0000000000000000 - offset 0x508[ 2.539447] debug_vm_pgtable: [init_args ]: args->mm is 0x000000002267cc9e(...)[ 2.552800] WARNING: CPU: 5 PID: 116 at include/linux/mm.h:2841 free_pud_range+0x8bc/0x8d0[ 2.552816] Modules linked in:[ 2.552843] CPU: 5 UID: 0 PID: 116 Comm: modprobe Not tainted 6.12.0-105.debug_vm2.el10.ppc64le+debug #1 VOLUNTARY[ 2.552859] Hardware name: IBM,9009-41A POWER9 (architected) 0x4e0202 0xf000005 of:IBM,FW910.00 (VL910_062) hv:phyp pSeries[ 2.552872] NIP: c0000000007eef3c LR: c0000000007eef30 CTR: c0000000003d8c90[ 2.552885] REGS: c0000000622e73b0 TRAP: 0700 Not tainted (6.12.0-105.debug_vm2.el10.ppc64le+debug)[ 2.552899] MSR: 800000000282b033 CR: 24002822 XER: 0000000a[ 2.552954] CFAR: c0000000008f03f0 IRQMASK: 0[ 2.552954] GPR00: c0000000007eef30 c0000000622e7650 c000000002b1ac00 0000000000000001[ 2.552954] GPR04: 0000000000000008 0000000000000000 c0000000007eef30 ffffffffffffffff[ 2.552954] GPR08: 00000000ffff00f5 0000000000000001 0000000000000048 0000000000004000[ 2.552954] GPR12: 00000003fa440000 c000000017ffa300 c0000000051d9f80 ffffffffffffffdb[ 2.552954] GPR16: 0000000000000000 0000000000000008 000000000000000a 60000000000000e0[ 2.552954] GPR20: 4080000000000000 c0000000113af038 00007fffcf130000 0000700000000000[ 2.552954] GPR24: c000000062a6a000 0000000000000001 8000000062a68000 0000000000000001[ 2.552954] GPR28: 000000000000000a c000000062ebc600 0000000000002000 c000000062ebc760[ 2.553170] NIP [c0000000007eef3c] free_pud_range+0x8bc/0x8d0[ 2.553185] LR [c0000000007eef30] free_pud_range+0x8b0/0x8d0[ 2.553199] Call Trace:[ 2.553207] [c0000000622e7650] [c0000000007eef30] free_pud_range+0x8b0/0x8d0 (unreliable)[ 2.553229] [c0000000622e7750] [c0000000007f40b4] free_pgd_range+0x284/0x3b0[ 2.553248] [c0000000622e7800] [c0000000007f4630] free_pgtables+0x450/0x570[ 2.553274] [c0000000622e78e0] [c0000000008161c0] exit_mmap+0x250/0x650[ 2.553292] [c0000000622e7a30] [c0000000001b95b8] __mmput+0x98/0x290[ 2.558344] [c0000000622e7a80] [c0000000001d1018] exit_mm+0x118/0x1b0[ 2.558361] [c0000000622e7ac0] [c0000000001d141c] do_exit+0x2ec/0x870[ 2.558376] [c0000000622e7b60] [c0000000001d1ca8] do_group_exit+0x88/0x150[ 2.558391] [c0000000622e7bb0] [c0000000001d1db8] sys_exit_group+0x48/0x50[ 2.558407] [c0000000622e7be0] [c00000000003d810] system_call_exception+0x1e0/0x4c0[ 2.558423] [c0000000622e7e50] [c00000000000d05c] system_call_vectored_common+0x15c/0x2ec(...)[ 2.558892] ---[ end trace 0000000000000000 ]---[ 2.559022] BUG: Bad rss-counter state mm:000000002267cc9e type:MM_ANONPAGES val:1[ 2.559037] BUG: non-zero pgtables_bytes on freeing mm: -6144Here the modprobe process ended up with an allocated mm_struct from themm_struct slab that was used before by the debug_vm_pgtable test.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: subpage: keep TOWRITE tag until folio is cleanedbtrfs_subpage_set_writeback() calls folio_start_writeback() the first timea folio is written back, and it also clears the PAGECACHE_TAG_TOWRITE tageven if there are still dirty blocks in the folio. This can break orderingguarantees, such as those required by btrfs_wait_ordered_extents().That ordering breakage leads to a real failure. For example, runninggeneric/464 on a zoned setup will hit the following ASSERT. This happensbecause the broken ordering fails to flush existing dirty pages before thefile size is truncated. assertion failed: !list_empty(&ordered->list) :: 0, in fs/btrfs/zoned.c:1899 ------------[ cut here ]------------ kernel BUG at fs/btrfs/zoned.c:1899!

In zoned mode orfor compressed writes, it locks several folios for delalloc and startswriting them out. Let's call the last locked folio folio X. Suppose thewrite range only partially covers folio X, leaving some pages dirty.Process A calls btrfs_subpage_set_writeback() when building a bio. Thisfunction call clears the TOWRITE tag of folio X, whose size = 8K andthe block size = 4K. It is following state. 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY) <-----> Process A will write this range.Now suppose process B concurrently calls writepages() with WB_SYNC_ALL. Itcalls tag_pages_for_writeback() to tag dirty folios withPAGECACHE_TAG_TOWRITE. Since folio X is still dirty, it gets tagged. Then,B collects tagged folios using filemap_get_folios_tag() and must wait forfolio X to be written before returning from writepages(). 0 4K 8K |/////|/////| (flag: DIRTY, tag: DIRTY|TOWRITE)However, between tagging and collecting, process A may callbtrfs_subpage_set_writeback() and clear folio X's TOWRITE tag. 0 4K 8K | |/////| (flag: DIRTY|WRITEBACK, tag: DIRTY)As a result, process B won't see folio X in its batch, and returns withoutwaiting for it. This breaks the WB_SYNC_ALL ordering requirement.Fix this by using btrfs_subpage_set_writeback_keepwrite(), which retainsthe TOWRITE tag. We now manually clear the tag only after the folio becomesclean, via the xas operation.

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: fix invalid accesses to ceph_connection_v1_infoThere is a place where generic code in messenger.c is reading andanother place where it is writing to con->v1 union member withoutchecking that the union member is active (i.e. msgr1 is in use).On 64-bit systems, con->v1.auth_retry overlaps with con->v2.out_iter,so such a read is almost guaranteed to return a bogus value instead of0 when msgr2 is in use. This ends up being fairly benign because theside effect is just the invalidation of the authorizer and successivefetching of new tickets.con->v1.connect_seq overlaps with con->v2.conn_bufs and the fact thatit's being written to can cause more serious consequences, but luckilyit's not something that happens often.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/vmalloc, mm/kasan: respect gfp mask in kasan_populate_vmalloc()kasan_populate_vmalloc() and its helpers ignore the caller's gfp_mask andalways allocate memory using the hardcoded GFP_KERNEL flag. This makesthem inconsistent with vmalloc(), which was recently extended to supportGFP_NOFS and GFP_NOIO allocations.Page table allocations performed during shadow population also ignore theexternal gfp_mask. To preserve the intended semantics of GFP_NOFS andGFP_NOIO, wrap the apply_to_page_range() calls into the appropriatememalloc scope.xfs calls vmalloc with GFP_NOFS, so this bug could lead to deadlock.There was a report herehttps://lkml.kernel.org/r/686ea951.050a0220.385921.0016.GAE@google.comThis patch: - Extends kasan_populate_vmalloc() and helpers to take gfp_mask; - Passes gfp_mask down to alloc_pages_bulk() and __get_free_page(); - Enforces GFP_NOFS/NOIO semantics with memalloc_*_save()/restore() around apply_to_page_range(); - Updates vmalloc.c and percpu allocator call sites accordingly.

Description: In the Linux kernel, the following vulnerability has been resolved:comedi: fix divide-by-zero in comedi_buf_munge()The comedi_buf_munge() function performs a modulo operation`async->munge_chan %= async->cmd.chanlist_len` without firstchecking if chanlist_len is zero. If a user program submits a command withchanlist_len set to zero, this causes a divide-by-zero error when the deviceprocesses data in the interrupt handler path.Add a check for zero chanlist_len at the beginning of thefunction, similar to the existing checks for !map andCMDF_RAWDATA flag. When chanlist_len is zero, updatemunge_count and return early, indicating the data washandled without munging.This prevents potential kernel panics from malformed user commands.

Description: In the Linux kernel, the following vulnerability has been resolved:sparc: fix accurate exception reporting in copy_{from_to}_user for UltraSPARC IIIAnthony Yznaga tracked down that a BUG_ON in ext4 code with large foliosenabled resulted from copy_from_user() returning impossibly large valuesgreater than the size to be copied. This lead to __copy_from_iter()returning impossible values instead of the actual number of bytes it wasable to copy.The BUG_ON has been reported inhttps://lore.kernel.org/r/b14f55642207e63e907965e209f6323a0df6dcee.camel@physik.fu-berlin.deThe referenced commit introduced exception handlers on user-space memoryreferences in copy_from_user and copy_to_user. These handlers return fromthe respective function and calculate the remaining bytes left to copyusing the current register contents. The exception handlers expect that%o2 has already been masked during the bulk copy loop, but the masking wasperformed after that loop. This will fix the return value of copy_from_userand copy_to_user in the faulting case. The behaviour of memcpy staysunchanged.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/xe/guc: Check GuC running state before deregistering exec queueIn normal operation, a registered exec queue is disabled andderegistered through the GuC, and freed only after the GuC confirmscompletion. However, if the driver is forced to unbind while the execqueue is still running, the user may call exec_destroy() after the GuChas already been stopped and CT communication disabled.In this case, the driver cannot receive a response from the GuC,preventing proper cleanup of exec queue resources. Fix this by directlyreleasing the resources when GuC is not running.Here is the failure dmesg log:"[ 468.089581] ---[ end trace 0000000000000000 ]---[ 468.089608] pci 0000:03:00.0: [drm] *ERROR* GT0: GUC ID manager unclean (1/65535)[ 468.090558] pci 0000:03:00.0: [drm] GT0: total 65535[ 468.090562] pci 0000:03:00.0: [drm] GT0: used 1[ 468.090564] pci 0000:03:00.0: [drm] GT0: range 1..1 (1)[ 468.092716] ------------[ cut here ]------------[ 468.092719] WARNING: CPU: 14 PID: 4775 at drivers/gpu/drm/xe/xe_ttm_vram_mgr.c:298 ttm_vram_mgr_fini+0xf8/0x130 [xe]"v2: use xe_uc_fw_is_running() instead of xe_guc_ct_enabled().

Description: In the Linux kernel, the following vulnerability has been resolved:x86/kvm: Force legacy PCI hole to UC when overriding MTRRs for TDX/SNPWhen running as an SNP or TDX guest under KVM, force the legacy PCI hole,i.e. memory between Top of Lower Usable DRAM and 4GiB, to be mapped as UCvia a forced variable MTRR range.In most KVM-based setups, legacy devices such as the HPET and TPM areenumerated via ACPI. ACPI enumeration includes a Memory32Fixed entry, andoptionally a SystemMemory descriptor for an OperationRegion, e.g. if thedevice needs to be accessed via a Control Method.If a SystemMemory entry is present, then the kernel's ACPI driver willauto-ioremap the region so that it can be accessed at will. However, theACPI spec doesn't provide a way to enumerate the memory type ofSystemMemory regions, i.e. there's no way to tell software that a regionmust be mapped as UC vs. WB, etc. As a result, Linux's ACPI driver alwaysmaps SystemMemory regions using ioremap_cache(), i.e. as WB on x86.The dedicated device drivers however, e.g. the HPET driver and TPM driver,want to map their associated memory as UC or WC, as accessing PCI devicesusing WB is unsupported.On bare metal and non-CoCO, the conflicting requirements "work" as firmwareconfigures the PCI hole (and other device memory) to be UC in the MTRRs.So even though the ACPI mappings request WB, they are forced to UC- in thekernel's tracking due to the kernel properly handling the MTRR overrides,and thus are compatible with the drivers' requested WC/UC-.With force WB MTRRs on SNP and TDX guests, the ACPI mappings get theirrequested WB if the ACPI mappings are established before the dedicateddriver code attempts to initialize the device. E.g. if acpi_init()runs before the corresponding device driver is probed, ACPI's WB mappingwill "win", and result in the driver's ioremap() failing because theexisting WB mapping isn't compatible with the requested WC/UC-.E.g. when a TPM is emulated by the hypervisor (ignoring the securityimplications of relying on what is allegedly an untrusted entity to storemeasurements), the TPM driver will request UC and fail: [ 1.730459] ioremap error for 0xfed40000-0xfed45000, requested 0x2, got 0x0 [ 1.732780] tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -12Note, the '0x2' and '0x0' values refer to "enum page_cache_mode", not x86'smemtypes (which frustratingly are an almost pure inversion; 2 == WB, 0 == UC).E.g. tracing mapping requests for TPM TIS yields: Mapping TPM TIS with req_type = 0 WARNING: CPU: 22 PID: 1 at arch/x86/mm/pat/memtype.c:530 memtype_reserve+0x2ab/0x460 Modules linked in: CPU: 22 UID: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.16.0-rc7+ #2 VOLUNTARY Tainted: [W]=WARN Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/29/2025 RIP: 0010:memtype_reserve+0x2ab/0x460 __ioremap_caller+0x16d/0x3d0 ioremap_cache+0x17/0x30 x86_acpi_os_ioremap+0xe/0x20 acpi_os_map_iomem+0x1f3/0x240 acpi_os_map_memory+0xe/0x20 acpi_ex_system_memory_space_handler+0x273/0x440 acpi_ev_address_space_dispatch+0x176/0x4c0 acpi_ex_access_region+0x2ad/0x530 acpi_ex_field_datum_io+0xa2/0x4f0 acpi_ex_extract_from_field+0x296/0x3e0 acpi_ex_read_data_from_field+0xd1/0x460 acpi_ex_resolve_node_to_value+0x2ee/0x530 acpi_ex_resolve_to_value+0x1f2/0x540 acpi_ds_evaluate_name_path+0x11b/0x190 acpi_ds_exec_end_op+0x456/0x960 acpi_ps_parse_loop+0x27a/0xa50 acpi_ps_parse_aml+0x226/0x600 acpi_ps_execute_method+0x172/0x3e0 acpi_ns_evaluate+0x175/0x5f0 acpi_evaluate_object+0x213/0x490 acpi_evaluate_integer+0x6d/0x140 acpi_bus_get_status+0x93/0x150 acpi_add_single_object+0x43a/0x7c0 acpi_bus_check_add+0x149/0x3a0 acpi_bus_check_add_1+0x16/0x30 acpi_ns_walk_namespace+0x22c/0x360 acpi_walk_namespace+0x15c/0x170 acpi_bus_scan+0x1dd/0x200 acpi_scan_init+0xe5/0x2b0 acpi_init+0x264/0x5b0 do_one_i---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:kernel/sys.c: fix the racy usage of task_lock(tsk->group_leader) in sys_prlimit64() pathsThe usage of task_lock(tsk->group_leader) in sys_prlimit64()->do_prlimit()path is very broken.sys_prlimit64() does get_task_struct(tsk) but this only protects task_structitself. If tsk != current and tsk is not a leader, this process can exit/execand task_lock(tsk->group_leader) may use the already freed task_struct.Another problem is that sys_prlimit64() can race with mt-exec which changes->group_leader. In this case do_prlimit() may take the wrong lock, or (worse)->group_leader may change between task_lock() and task_unlock().Change sys_prlimit64() to take tasklist_lock when necessary.

Description: In the Linux kernel, the following vulnerability has been resolved:net: openvswitch: remove never-working support for setting nsh fieldsThe validation of the set(nsh(...)) action is completely wrong.It runs through the nsh_key_put_from_nlattr() function that is thesame function that validates NSH keys for the flow match and thepush_nsh() action. However, the set(nsh(...)) has a very differentmemory layout. Nested attributes in there are doubled in size incase of the masked set(). That makes proper validation impossible.There is also confusion in the code between the 'masked' flag, thatsays that the nested attributes are doubled in size containing boththe value and the mask, and the 'is_mask' that says that the valuewe're parsing is the mask. This is causing kernel crash on trying towrite into mask part of the match with SW_FLOW_KEY_PUT() duringvalidation, while validate_nsh() doesn't allocate any memory for it: BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 1c2383067 P4D 1c2383067 PUD 20b703067 PMD 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 8 UID: 0 Kdump: loaded Not tainted 6.17.0-rc4+ #107 PREEMPT(voluntary) RIP: 0010:nsh_key_put_from_nlattr+0x19d/0x610 [openvswitch] Call Trace: validate_nsh+0x60/0x90 [openvswitch] validate_set.constprop.0+0x270/0x3c0 [openvswitch] __ovs_nla_copy_actions+0x477/0x860 [openvswitch] ovs_nla_copy_actions+0x8d/0x100 [openvswitch] ovs_packet_cmd_execute+0x1cc/0x310 [openvswitch] genl_family_rcv_msg_doit+0xdb/0x130 genl_family_rcv_msg+0x14b/0x220 genl_rcv_msg+0x47/0xa0 netlink_rcv_skb+0x53/0x100 genl_rcv+0x24/0x40 netlink_unicast+0x280/0x3b0 netlink_sendmsg+0x1f7/0x430 ____sys_sendmsg+0x36b/0x3a0 ___sys_sendmsg+0x87/0xd0 __sys_sendmsg+0x6d/0xd0 do_syscall_64+0x7b/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7eThe third issue with this process is that while trying to convertthe non-masked set into masked one, validate_set() copies and doublesthe size of the OVS_KEY_ATTR_NSH as if it didn't have any nestedattributes. It should be copying each nested attribute and doublingthem in size independently. And the process must be properly reversedduring the conversion back from masked to a non-masked variant duringthe flow dump.In the end, the only two outcomes of trying to use this action areeither validation failure or a kernel crash. And if somehow someonemanages to install a flow with such an action, it will most definitelynot do what it is supposed to, since all the keys and the masks aremixed up.Fixing all the issues is a complex task as it requires re-writingmost of the validation code.Given that and the fact that this functionality never worked sinceintroduction, let's just remove it altogether. It's better tore-introduce it later with a proper implementation instead of tryingto fix it in stable releases.

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

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: RX, Fix generating skb from non-linear xdp_buff for striding RQXDP programs can change the layout of an xdp_buff throughbpf_xdp_adjust_tail() and bpf_xdp_adjust_head(). Therefore, the drivercannot assume the size of the linear data area nor fragments. Fix thebug in mlx5 by generating skb according to xdp_buff after XDP programsrun.Currently, when handling multi-buf XDP, the mlx5 driver assumes thelayout of an xdp_buff to be unchanged. That is, the linear data areacontinues to be empty and fragments remain the same. This may causethe driver to generate erroneous skb or triggering a kernelwarning. When an XDP program added linear data throughbpf_xdp_adjust_head(), the linear data will be ignored asmlx5e_build_linear_skb() builds an skb without linear data and thenpull data from fragments to fill the linear data area. When an XDPprogram has shrunk the non-linear data through bpf_xdp_adjust_tail(),the delta passed to __pskb_pull_tail() may exceed the actual nonlineardata size and trigger the BUG_ON in it.To fix the issue, first record the original number of fragments. If thenumber of fragments changes after the XDP program runs, rewind the endfragment pointer by the difference and recalculate the truesize. Then,build the skb with the linear data area matching the xdp_buff. Finally,only pull data in if there is non-linear data and fill the linear partup to 256 bytes.

Description: In the Linux kernel, the following vulnerability has been resolved:x86/fpu: Ensure XFD state on signal deliverySean reported [1] the following splat when running KVM tests: WARNING: CPU: 232 PID: 15391 at xfd_validate_state+0x65/0x70 Call Trace: fpu__clear_user_states+0x9c/0x100 arch_do_signal_or_restart+0x142/0x210 exit_to_user_mode_loop+0x55/0x100 do_syscall_64+0x205/0x2c0 entry_SYSCALL_64_after_hwframe+0x4b/0x53Chao further identified [2] a reproducible scenario involving signaldelivery: a non-AMX task is preempted by an AMX-enabled task whichmodifies the XFD MSR.When the non-AMX task resumes and reloads XSTATE with init values,a warning is triggered due to a mismatch between fpstate::xfd and theCPU's current XFD state. fpu__clear_user_states() does not currentlyre-synchronize the XFD state after such preemption.Invoke xfd_update_state() which detects and corrects the mismatch ifthere is a dynamic feature.This also benefits the sigreturn path, as fpu__restore_sig() may callfpu__clear_user_states() when the sigframe is inaccessible.[ dhansen: minor changelog munging ]

Meanwhile,consider that blkcg_mutex is held after queue is freezed from policydeactivation, also convert blkg_alloc() to use GFP_NOIO.

Description: In the Linux kernel, the following vulnerability has been resolved:s390: Disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAPAs reported by Luiz Capitulino enabling HVO on s390 leads to reproduciblecrashes. The problem is that kernel page tables are modified withoutflushing corresponding TLB entries.Even if it looks like the empty flush_tlb_all() implementation on s390 isthe problem, it is actually a different problem: on s390 it is not allowedto replace an active/valid page table entry with another valid page tableentry without the detour over an invalid entry. A direct replacement maylead to random crashes and/or data corruption.In order to invalidate an entry special instructions have to be used(e.g. ipte or idte). Alternatively there are also special instructionsavailable which allow to replace a valid entry with a different validentry (e.g. crdte or cspg).Given that the HVO code currently does not provide the hooks to allow foran implementation which is compliant with the s390 architecturerequirements, disable ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP again, which isbasically a revert of the original patch which enabled it.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved:ice: fix PTP cleanup on driver removal in error pathImprove the cleanup on releasing PTP resources in error path.The error case might happen either at the driver probe and PTPfeature initialization or on PTP restart (errors in reset handling, NVMupdate etc).

Description: In the Linux kernel, the following vulnerability has been resolved:cifs: fix memory leak in smb3_fs_context_parse_param error pathAdd proper cleanup of ctx->source and fc->source to thecifs_parse_mount_err error handler. This ensures that memory allocatedfor the source strings is correctly freed on all error paths, matchingthe cleanup already performed in the success path bysmb3_cleanup_fs_context_contents().Pointers are also set to NULL after freeing to prevent potentialdouble-free issues.This change fixes a memory leak originally detected by syzbot. Theleak occurred when processing Opt_source mount options if an errorhappened after ctx->source and fc->source were successfullyallocated but before the function completed.The specific leak sequence was:1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory3. A subsequent error jumps to cifs_parse_mount_err4. The old error handler freed passwords but not the source strings,causing the memory to leak.This issue was not addressed by commit e8c73eb7db0a ("cifs: client:fix memory leak in smb3_fs_context_parse_param"), which only fixedleaks from repeated fsconfig() calls but not this error path.Patch updated with minor change suggested by kernel test robot

Description: In the Linux kernel, the following vulnerability has been resolved:net: netpoll: fix incorrect refcount handling causing incorrect cleanupcommit efa95b01da18 ("netpoll: fix use after free") incorrectlyignored the refcount and prematurely set dev->npinfo to NULL duringnetpoll cleanup, leading to improper behavior and memory leaks.Scenario causing lack of proper cleanup:1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is allocated, and refcnt = 1 - Keep in mind that npinfo is shared among all netpoll instances. In this case, there is just one.2) Another netpoll is also associated with the same NIC and npinfo->refcnt += 1. - Now dev->npinfo->refcnt = 2; - There is just one npinfo associated to the netdev.3) When the first netpolls goes to clean up: - The first cleanup succeeds and clears np->dev->npinfo, ignoring refcnt. - It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);` - Set dev->npinfo = NULL, without proper cleanup - No ->ndo_netpoll_cleanup() is either called4) Now the second target tries to clean up - The second cleanup fails because np->dev->npinfo is already NULL. * In this case, ops->ndo_netpoll_cleanup() was never called, and the skb pool is not cleaned as well (for the second netpoll instance) - This leaks npinfo and skbpool skbs, which is clearly reported by kmemleak.Revert commit efa95b01da18 ("netpoll: fix use after free") and addsclarifying comments emphasizing that npinfo cleanup should only happenonce the refcount reaches zero, ensuring stable and correct netpollbehavior.

However, this does not fully solve the race, as a newwork item can still be scheduled *after* flush_work() completes butbefore the gadget's memory is freed, leading to the same use-after-free.This patch fixes the race condition robustly by introducing a 'teardown'flag and a 'state_lock' spinlock to the usb_gadget struct. The flag isset during cleanup in usb_del_gadget() *before* calling flush_work() toprevent any new work from being scheduled once cleanup has commenced.The scheduling site, usb_gadget_set_state(), now checks this flag underthe lock before queueing the work, thus safely closing the race window.

Description: In the Linux kernel, the following vulnerability has been resolved:drm, fbcon, vga_switcheroo: Avoid race condition in fbcon setupProtect vga_switcheroo_client_fb_set() with console lock. Avoids OOBaccess in fbcon_remap_all(). Without holding the console lock the callraces with switching outputs.VGA switcheroo calls fbcon_remap_all() when switching clients. The fbconfunction uses struct fb_info.node, which is set by register_framebuffer().As the fb-helper code currently sets up VGA switcheroo before registeringthe framebuffer, the value of node is -1 and therefore not a legal value.For example, fbcon uses the value within set_con2fb_map() [1] as an indexinto an array.Moving vga_switcheroo_client_fb_set() after register_framebuffer() canresult in VGA switching that does not switch fbcon correctly.Therefore move vga_switcheroo_client_fb_set() under fbcon_fb_registered(),which already holds the console lock. Fbdev calls fbcon_fb_registered()from within register_framebuffer(). Serializes the helper with VGAswitcheroo's call to fbcon_remap_all().Although vga_switcheroo_client_fb_set() takes an instance of struct fb_infoas parameter, it really only needs the contained fbcon state. Moving thecall to fbcon initialization is therefore cleaner than before. Only amdgpu,i915, nouveau and radeon support vga_switcheroo. For all other drivers,this change does nothing.

Description: In the Linux kernel, the following vulnerability has been resolved:net: atlantic: fix fragment overflow handling in RX pathThe atlantic driver can receive packets with more than MAX_SKB_FRAGS (17)fragments when handling large multi-descriptor packets. This causes anout-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic.The issue occurs because the driver doesn't check the total number offragments before calling skb_add_rx_frag(). When a packet requires morethan MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds.Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE,then all fragments are accounted for. And reusing the existing check toprevent the overflow earlier in the code path.This crash occurred in production with an Aquantia AQC113 10G NIC.Stack trace from production environment:```RIP: 0010:skb_add_rx_frag_netmem+0x29/0xd0Code: 90 f3 0f 1e fa 0f 1f 44 00 00 48 89 f8 41 89ca 48 89 d7 48 63 ce 8b 90 c0 00 00 00 48 c1 e1 04 48 01 ca 48 03 90c8 00 00 00 <48> 89 7a 30 44 89 52 3c 44 89 42 38 40 f6 c7 01 75 74 4889 fa 83RSP: 0018:ffffa9bec02a8d50 EFLAGS: 00010287RAX: ffff925b22e80a00 RBX: ffff925ad38d2700 RCX:fffffffe0a0c8000RDX: ffff9258ea95bac0 RSI: ffff925ae0a0c800 RDI:0000000000037a40RBP: 0000000000000024 R08: 0000000000000000 R09:0000000000000021R10: 0000000000000848 R11: 0000000000000000 R12:ffffa9bec02a8e24R13: ffff925ad8615570 R14: 0000000000000000 R15:ffff925b22e80a00FS: 0000000000000000(0000)GS:ffff925e47880000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: ffff9258ea95baf0 CR3: 0000000166022004 CR4:0000000000f72ef0PKRU: 55555554Call Trace:aq_ring_rx_clean+0x175/0xe60 [atlantic]? aq_ring_rx_clean+0x14d/0xe60 [atlantic]? aq_ring_tx_clean+0xdf/0x190 [atlantic]? kmem_cache_free+0x348/0x450? aq_vec_poll+0x81/0x1d0 [atlantic]? __napi_poll+0x28/0x1c0? net_rx_action+0x337/0x420```Changes in v4:- Add Fixes: tag to satisfy patch validation requirements.Changes in v3:- Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE, then all fragments are accounted for.

Description: In the Linux kernel, the following vulnerability has been resolved:Bluetooth: hci_core: lookup hci_conn on RX path on protocol sideThe hdev lock/lookup/unlock/use pattern in the packet RX path doesn'tensure hci_conn* is not concurrently modified/deleted. This lockingappears to be leftover from before conn_hash started using RCUcommit bf4c63252490b ("Bluetooth: convert conn hash to RCU")and not clear if it had purpose since then.Currently, there are code paths that delete hci_conn* from elsewherethan the ordered hdev->workqueue where the RX work runs in. E.g.commit 5af1f84ed13a ("Bluetooth: hci_sync: Fix UAF on hci_abort_conn_sync")introduced some of these, and there probably were a few others beforeit. It's better to do the locking so that even if these runconcurrently no UAF is possible.Move the lookup of hci_conn and associated socket-specific conn toprotocol recv handlers, and do them within a single critical sectionto cover hci_conn* usage and lookup.syzkaller has reported a crash that appears to be this issue: [Task hdev->workqueue] [Task 2] hci_disconnect_all_sync l2cap_recv_acldata(hcon) hci_conn_get(hcon) hci_abort_conn_sync(hcon) hci_dev_lock hci_dev_lock hci_conn_del(hcon) v-------------------------------- hci_dev_unlock hci_conn_put(hcon) conn = hcon->l2cap_data (UAF)

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_cake: Fix incorrect qlen reduction in cake_dropIn cake_drop(), qdisc_tree_reduce_backlog() is used to update the qlenand backlog of the qdisc hierarchy. Its caller, cake_enqueue(), assumesthat the parent qdisc will enqueue the current packet. However, thisassumption breaks when cake_enqueue() returns NET_XMIT_CN: the parentqdisc stops enqueuing current packet, leaving the tree qlen/backlogaccounting inconsistent. This mismatch can lead to a NULL dereference(e.g., when the parent Qdisc is qfq_qdisc).This patch computes the qlen/backlog delta in a more robust way byobserving the difference before and after the series of cake_drop()calls, and then compensates the qdisc tree accounting if cake_enqueue()returns NET_XMIT_CN.To ensure correct compensation when ACK thinning is enabled, a newvariable is introduced to keep qlen unchanged.

There have been many inconsistencies in the file systemdata.In the case of file system data inconsistency, for example, if the blockbitmap of a referenced block is not set, it can lead to the situation wherea block being committed is allocated and used again. As a result, thefollowing condition will not be satisfied then trigger BUG_ON. Of course,it is entirely possible to construct a problematic image that can triggerthis BUG_ON through specific operations. In fact, I have constructed suchan image and easily reproduced this issue.Therefore, J_ASSERT() holds true only under ideal conditions, but it maynot necessarily be satisfied in exceptional scenarios. Using J_ASSERT()directly in abnormal situations would cause the system to crash, which isclearly not what we want. So here we directly trigger a JBD abort insteadof immediately invoking BUG_ON.

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Do not let BPF test infra emit invalid GSO types to stackYinhao et al. reported that their fuzzer tool was able to trigger askb_warn_bad_offload() from netif_skb_features() -> gso_features_check().When a BPF program - triggered via BPF test infra - pushes the packetto the loopback device via bpf_clone_redirect() then mentioned offloadwarning can be seen. GSO-related features are then rightfully disabled.We get into this situation due to convert___skb_to_skb() settinggso_segs and gso_size but not gso_type. Technically, it makes sensethat this warning triggers since the GSO properties are malformed dueto the gso_type. Potentially, the gso_type could be marked non-trustworthythrough setting it at least to SKB_GSO_DODGY without any other specificassumptions, but that also feels wrong given we should not go furtherinto the GSO engine in the first place.The checks were added in 121d57af308d ("gso: validate gso_type in GSOhandlers") because there were malicious (syzbot) senders that combinea protocol with a non-matching gso_type. If we would want to drop suchpackets, gso_features_check() currently only returns feature flags vianetif_skb_features(), so one location for potentially dropping such skbscould be validate_xmit_unreadable_skb(), but then otoh it would bean additional check in the fast-path for a very corner case. Givenbpf_clone_redirect() is the only place where BPF test infra could emitsuch packets, lets reject them right there.

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

Description: In the Linux kernel, the following vulnerability has been resolved:char: applicom: fix NULL pointer dereference in ac_ioctlDiscovered by Atuin - Automated Vulnerability Discovery Engine.In ac_ioctl, the validation of IndexCard and the check for a validRamIO pointer are skipped when cmd is 6. However, the functionunconditionally executes readb(apbs[IndexCard].RamIO + VERS) at theend.If cmd is 6, IndexCard may reference a board that does not exist(where RamIO is NULL), leading to a NULL pointer dereference.Fix this by skipping the readb access when cmd is 6, as thiscommand is a global information query and does not target a specificboard context.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: vfs: fix race on m_flags in vfs_cacheksmbd maintains delete-on-close and pending-delete state inksmbd_inode->m_flags. In vfs_cache.c this field is accessed underinconsistent locking: some paths read and modify m_flags underci->m_lock while others do so without taking the lock at all.Examples: - ksmbd_query_inode_status() and __ksmbd_inode_close() use ci->m_lock when checking or updating m_flags. - ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(), ksmbd_clear_inode_pending_delete() and ksmbd_fd_set_delete_on_close() used to read and modify m_flags without ci->m_lock.This creates a potential data race on m_flags when multiple threadsopen, close and delete the same file concurrently. In the worst casedelete-on-close and pending-delete bits can be lost or observed in aninconsistent state, leading to confusing delete semantics (files thatstay on disk after delete-on-close, or files that disappear while stillin use).Fix it by: - Making ksmbd_query_inode_status() look at m_flags under ci->m_lock after dropping inode_hash_lock. - Adding ci->m_lock protection to all helpers that read or modify m_flags (ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(), ksmbd_clear_inode_pending_delete(), ksmbd_fd_set_delete_on_close()). - Keeping the existing ci->m_lock protection in __ksmbd_inode_close(), and moving the actual unlink/xattr removal outside the lock.This unifies the locking around m_flags and removes the data race whilepreserving the existing delete-on-close behaviour.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslotReject attempts to disable KVM_MEM_GUEST_MEMFD on a memslot that wasinitially created with a guest_memfd binding, as KVM doesn't supporttoggling KVM_MEM_GUEST_MEMFD on existing memslots. KVM prevents enablingKVM_MEM_GUEST_MEMFD, but doesn't prevent clearing the flag.Failure to reject the new memslot results in a use-after-free due to KVMnot unbinding from the guest_memfd instance. Unbinding on a FLAGS_ONLYchange is easy enough, and can/will be done as a hardening measure (inanticipation of KVM supporting dirty logging on guest_memfd at some point),but fixing the use-after-free would only address the immediate symptom. ================================================================== BUG: KASAN: slab-use-after-free in kvm_gmem_release+0x362/0x400 [kvm] Write of size 8 at addr ffff8881111ae908 by task repro/745 CPU: 7 UID: 1000 PID: 745 Comm: repro Not tainted 6.18.0-rc6-115d5de2eef3-next-kasan #3 NONE Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 Call Trace: dump_stack_lvl+0x51/0x60 print_report+0xcb/0x5c0 kasan_report+0xb4/0xe0 kvm_gmem_release+0x362/0x400 [kvm] __fput+0x2fa/0x9d0 task_work_run+0x12c/0x200 do_exit+0x6ae/0x2100 do_group_exit+0xa8/0x230 __x64_sys_exit_group+0x3a/0x50 x64_sys_call+0x737/0x740 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 RIP: 0033:0x7f581f2eac31 Allocated by task 745 on cpu 6 at 9.746971s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_kmalloc+0x77/0x90 kvm_set_memory_region.part.0+0x652/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53 Freed by task 745 on cpu 6 at 9.747467s: kasan_save_stack+0x20/0x40 kasan_save_track+0x13/0x50 __kasan_save_free_info+0x37/0x50 __kasan_slab_free+0x3b/0x60 kfree+0xf5/0x440 kvm_set_memslot+0x3c2/0x1160 [kvm] kvm_set_memory_region.part.0+0x86a/0x1110 [kvm] kvm_vm_ioctl+0x14b0/0x3290 [kvm] __x64_sys_ioctl+0x129/0x1a0 do_syscall_64+0x5b/0x900 entry_SYSCALL_64_after_hwframe+0x4b/0x53

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring: fix filename leak in __io_openat_prep() __io_openat_prep() allocates a struct filename using getname(). However,for the condition of the file being installed in the fixed file table aswell as having O_CLOEXEC flag set, the function returns early. At thatpoint, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,the memory for the newly allocated struct filename is not cleaned up,causing a memory leak.Fix this by setting the REQ_F_NEED_CLEANUP for the request just after thesuccessful getname() call, so that when the request is torn down, thefilename will be cleaned up, along with other resources needing cleanup.

Description: In the Linux kernel, the following vulnerability has been resolved:net/mlx5: fw_tracer, Validate format string parametersAdd validation for format string parameters in the firmware tracer toprevent potential security vulnerabilities and crashes from malformedformat strings received from firmware.The firmware tracer receives format strings from the device firmware anduses them to format trace messages. Without proper validation, badfirmware could provide format strings with invalid format specifiers(e.g., %s, %p, %n) that could lead to crashes, or other undefinedbehavior.Add mlx5_tracer_validate_params() to validate that all format specifiersin trace strings are limited to safe integer/hex formats (%x, %d, %i,%u, %llx, %lx, etc.). Reject strings containing other format types thatcould be used to access arbitrary memory or cause crashes.Invalid format strings are added to the trace output for visibility with"BAD_FORMAT: " prefix.

Description: In the Linux kernel, the following vulnerability has been resolved:Input: alps - fix use-after-free bugs caused by dev3_register_workThe dev3_register_work delayed work item is initialized withinalps_reconnect() and scheduled upon receipt of the first barePS/2 packet from an external PS/2 device connected to the ALPStouchpad. During device detachment, the original implementationcalls flush_workqueue() in psmouse_disconnect() to ensurecompletion of dev3_register_work. However, the flush_workqueue()in psmouse_disconnect() only blocks and waits for work items thatwere already queued to the workqueue prior to its invocation. Anywork items submitted after flush_workqueue() is called are notincluded in the set of tasks that the flush operation awaits.This means that after flush_workqueue() has finished executing,the dev3_register_work could still be scheduled. Although thepsmouse state is set to PSMOUSE_CMD_MODE in psmouse_disconnect(),the scheduling of dev3_register_work remains unaffected.The race condition can occur as follows:CPU 0 (cleanup path) | CPU 1 (delayed work)psmouse_disconnect() | psmouse_set_state() | flush_workqueue() | alps_report_bare_ps2_packet() alps_disconnect() | psmouse_queue_work() kfree(priv); // FREE | alps_register_bare_ps2_mouse() | priv = container_of(work...); // USE | priv->dev3 // USEAdd disable_delayed_work_sync() in alps_disconnect() to ensurethat dev3_register_work is properly canceled and prevented fromexecuting after the alps_data structure has been deallocated.This bug is identified by static analysis.

Description: In the Linux kernel, the following vulnerability has been resolved:ublk: fix deadlock when reading partition tableWhen one process(such as udev) opens ublk block device (e.g., to readthe partition table via bdev_open()), a deadlock[1] can occur:1. bdev_open() grabs disk->open_mutex2. The process issues read I/O to ublk backend to read partition table3. In __ublk_complete_rq(), blk_update_request() or blk_mq_end_request() runs bio->bi_end_io() callbacks4. If this triggers fput() on file descriptor of ublk block device, the work may be deferred to current task's task work (see fput() implementation)5. This eventually calls blkdev_release() from the same context6. blkdev_release() tries to grab disk->open_mutex again7. Deadlock: same task waiting for a mutex it already holdsThe fix is to run blk_update_request() and blk_mq_end_request() with bottomhalves disabled. This forces blkdev_release() to run in kernel work-queuecontext instead of current task work context, and allows ublk server to makeforward progress, and avoids the deadlock.[axboe: rewrite comment in ublk]

However, kinfo->num_tqps is set tomin(new_tqps, hdev->num_tqps); Therefore, kinfo->num_tqps may be smallerthan hdev->num_tqps, which causes some hdev->htqp[i] to remainuninitialized in hclgevf_knic_setup().Thus, this patch allocates hdev->htqp and kinfo->tqp using hdev->num_tqps,ensuring that the lengths of hdev->htqp and kinfo->tqp are consistentand that all elements are properly initialized.

Description: In the Linux kernel, the following vulnerability has been resolved:f2fs: invalidate dentry cache on failed whiteout creationF2FS can mount filesystems with corrupted directory depth values thatget runtime-clamped to MAX_DIR_HASH_DEPTH. When RENAME_WHITEOUToperations are performed on such directories, f2fs_rename performsdirectory modifications (updating target entry and deleting sourceentry) before attempting to add the whiteout entry via f2fs_add_link.If f2fs_add_link fails due to the corrupted directory structure, thefunction returns an error to VFS, but the partial directorymodifications have already been committed to disk. VFS assumes theentire rename operation failed and does not update the dentry cache,leaving stale mappings.In the error path, VFS does not call d_move() to update the dentrycache. This results in new_dentry still pointing to the old inode(new_inode) which has already had its i_nlink decremented to zero.The stale cache causes subsequent operations to incorrectly referencethe freed inode.This causes subsequent operations to use cached dentry information thatno longer matches the on-disk state. When a second rename targets thesame entry, VFS attempts to decrement i_nlink on the stale inode, whichmay already have i_nlink=0, triggering a WARNING in drop_nlink().Example sequence:1. First rename (RENAME_WHITEOUT): file2 -> file1 - f2fs updates file1 entry on disk (points to inode 8) - f2fs deletes file2 entry on disk - f2fs_add_link(whiteout) fails (corrupted directory) - Returns error to VFS - VFS does not call d_move() due to error - VFS cache still has: file1 -> inode 7 (stale!) - inode 7 has i_nlink=0 (already decremented)2. Second rename: file3 -> file1 - VFS uses stale cache: file1 -> inode 7 - Tries to drop_nlink on inode 7 (i_nlink already 0) - WARNING in drop_nlink()Fix this by explicitly invalidating old_dentry and new_dentry whenf2fs_add_link fails during whiteout creation. This forces VFS torefresh from disk on subsequent operations, ensuring cache consistencyeven when the rename partially succeeds.Reproducer:1. Mount F2FS image with corrupted i_current_depth2. renameat2(file2, file1, RENAME_WHITEOUT)3. renameat2(file3, file1, 0)4. System triggers WARNING in drop_nlink()

Description: In the Linux kernel, the following vulnerability has been resolved:functionfs: fix the open/removal racesffs_epfile_open() can race with removal, ending up with file->private_datapointing to freed object.There is a total count of opened files on functionfs (both ep0 anddynamic ones) and when it hits zero, dynamic files get removed.Unfortunately, that removal can happen while another thread isin ffs_epfile_open(), but has not incremented the count yet.In that case open will succeed, leaving us with UAF on any subsequentread() or write().The root cause is that ffs->opened is misused; atomic_dec_and_test() vs.atomic_add_return() is not a good idea, when object remains visible allalong.To untangle that * serialize openers on ffs->mutex (both for ep0 and for dynamic files) * have dynamic ones use atomic_inc_not_zero() and fail if we hadzero ->opened; in that case the file we are opening is doomed. * have the inodes of dynamic files marked on removal (from thecallback of simple_recursive_removal()) - clear ->i_private there. * have open of dynamic ones verify they hadn't been already removed,along with checking that state is FFS_ACTIVE.

Actually,slab system will only create one slab cache core structure which hasslab name of "f2fs_xattr_entry-7:3", and two slab caches share the samestructure and cache address.So, if we destroy f2fs_xattr_entry-7:3 cache w/ cache address, it willdecrease reference count of slab cache, rather than release slab cacheentirely, since there is one more user has referenced the cache.Then, if we try to create slab cache w/ name "f2fs_xattr_entry-7:3" again,slab system will find that there is existed cache which has the same nameand trigger the warning.Let's changes to use global inline_xattr_slab instead of per-sb slab cachefor fixing.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: Discard Beacon frames to non-broadcast addressBeacon frames are required to be sent to the broadcast address, see IEEEStd 802.11-2020, 11.1.3.1 ("The Address 1 field of the Beacon .. frameshall be set to the broadcast address"). A unicast Beacon frame might beused as a targeted attack to get one of the associated STAs to dosomething (e.g., using CSA to move it to another channel). As such, itis better have strict filtering for this on the received side anddiscard all Beacon frames that are sent to an unexpected address.This is even more important for cases where beacon protection is used.The current implementation in mac80211 is correctly discarding unicastBeacon frames if the Protected Frame bit in the Frame Control field isset to 0. However, if that bit is set to 1, the logic used for checkingfor configured BIGTK(s) does not actually work. If the driver does nothave logic for dropping unicast Beacon frames with Protected Frame bit1, these frames would be accepted in mac80211 processing as valid Beaconframes even though they are not protected. This would allow beaconprotection to be bypassed. While the logic for checking beaconprotection could be extended to cover this corner case, a more genericcheck for discard all Beacon frames based on A1=unicast address coversthis without needing additional changes.Address all these issues by dropping received Beacon frames if they aresent to a non-broadcast address.

Description: In the Linux kernel, the following vulnerability has been resolved:LoongArch: BPF: Sign extend kfunc call argumentsThe kfunc calls are native calls so they should follow LoongArch callingconventions. Sign extend its arguments properly to avoid kernel panic.This is done by adding a new emit_abi_ext() helper. The emit_abi_ext()helper performs extension in place meaning a value already store in thetarget register (Note: this is different from the existing sign_extend()helper and thus we can't reuse it).

Description: In the Linux kernel, the following vulnerability has been resolved:dm-verity: disable recursive forward error correctionThere are two problems with the recursive correction:1. It may cause denial-of-service. In fec_read_bufs, there is a loop thathas 253 iterations. For each iteration, we may call verity_hash_for_blockrecursively. There is a limit of 4 nested recursions - that means thatthere may be at most 253^4 (4 billion) iterations. Red Hat QE teamactually created an image that pushes dm-verity to this limit - and thisimage just makes the udev-worker process get stuck in the 'D' state.2. It doesn't work. In fec_read_bufs we store data into the variable"fio->bufs", but fio bufs is shared between recursive invocations, if"verity_hash_for_block" invoked correction recursively, it wouldoverwrite partially filled fio->bufs.

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: tegra-adma: Fix use-after-freeA use-after-free bug exists in the Tegra ADMA driver when audio streamsare terminated, particularly during XRUN conditions. The issue occurswhen the DMA buffer is freed by tegra_adma_terminate_all() before thevchan completion tasklet finishes accessing it.The race condition follows this sequence: 1. DMA transfer completes, triggering an interrupt that schedules the completion tasklet (tasklet has not executed yet) 2. Audio playback stops, calling tegra_adma_terminate_all() which frees the DMA buffer memory via kfree() 3. The scheduled tasklet finally executes, calling vchan_complete() which attempts to access the already-freed memorySince tasklets can execute at any time after being scheduled, there isno guarantee that the buffer will remain valid when vchan_complete()runs.Fix this by properly synchronizing the virtual channel completion: - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the descriptors as terminated instead of freeing the descriptor. - Add the callback tegra_adma_synchronize() that calls vchan_synchronize() which kills any pending tasklets and frees any terminated descriptors.Crash logs:[ 337.427523] BUG: KASAN: use-after-free in vchan_complete+0x124/0x3b0[ 337.427544] Read of size 8 at addr ffff000132055428 by task swapper/0/0[ 337.427562] Call trace:[ 337.427564] dump_backtrace+0x0/0x320[ 337.427571] show_stack+0x20/0x30[ 337.427575] dump_stack_lvl+0x68/0x84[ 337.427584] print_address_description.constprop.0+0x74/0x2b8[ 337.427590] kasan_report+0x1f4/0x210[ 337.427598] __asan_load8+0xa0/0xd0[ 337.427603] vchan_complete+0x124/0x3b0[ 337.427609] tasklet_action_common.constprop.0+0x190/0x1d0[ 337.427617] tasklet_action+0x30/0x40[ 337.427623] __do_softirq+0x1a0/0x5c4[ 337.427628] irq_exit+0x110/0x140[ 337.427633] handle_domain_irq+0xa4/0xe0[ 337.427640] gic_handle_irq+0x64/0x160[ 337.427644] call_on_irq_stack+0x20/0x4c[ 337.427649] do_interrupt_handler+0x7c/0x90[ 337.427654] el1_interrupt+0x30/0x80[ 337.427659] el1h_64_irq_handler+0x18/0x30[ 337.427663] el1h_64_irq+0x7c/0x80[ 337.427667] cpuidle_enter_state+0xe4/0x540[ 337.427674] cpuidle_enter+0x54/0x80[ 337.427679] do_idle+0x2e0/0x380[ 337.427685] cpu_startup_entry+0x2c/0x70[ 337.427690] rest_init+0x114/0x130[ 337.427695] arch_call_rest_init+0x18/0x24[ 337.427702] start_kernel+0x380/0x3b4[ 337.427706] __primary_switched+0xc0/0xc8

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: always detect conflicting inodes when logging inode refsAfter rename exchanging (either with the rename exchange operation orregular renames in multiple non-atomic steps) two inodes and at leastone of them is a directory, we can end up with a log tree that containsonly of the inodes and after a power failure that can result in an attemptto delete the other inode when it should not because it was not deletedbefore the power failure. In some case that delete attempt fails whenthe target inode is a directory that contains a subvolume inside it, sincethe log replay code is not prepared to deal with directory entries thatpoint to root items (only inode items).1) We have directories "dir1" (inode A) and "dir2" (inode B) under the same parent directory;2) We have a file (inode C) under directory "dir1" (inode A);3) We have a subvolume inside directory "dir2" (inode B);4) All these inodes were persisted in a past transaction and we are currently at transaction N;5) We rename the file (inode C), so at btrfs_log_new_name() we update inode C's last_unlink_trans to N;6) We get a rename exchange for "dir1" (inode A) and "dir2" (inode B), so after the exchange "dir1" is inode B and "dir2" is inode A. During the rename exchange we call btrfs_log_new_name() for inodes A and B, but because they are directories, we don't update their last_unlink_trans to N;7) An fsync against the file (inode C) is done, and because its inode has a last_unlink_trans with a value of N we log its parent directory (inode A) (through btrfs_log_all_parents(), called from btrfs_log_inode_parent()).8) So we end up with inode B not logged, which now has the old name of inode A. At copy_inode_items_to_log(), when logging inode A, we did not check if we had any conflicting inode to log because inode A has a generation lower than the current transaction (created in a past transaction);9) After a power failure, when replaying the log tree, since we find that inode A has a new name that conflicts with the name of inode B in the fs tree, we attempt to delete inode B... this is wrong since that directory was never deleted before the power failure, and because there is a subvolume inside that directory, attempting to delete it will fail since replay_dir_deletes() and btrfs_unlink_inode() are not prepared to deal with dir items that point to roots instead of inodes.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix NULL dereference on root when tracing inode evictionWhen evicting an inode the first thing we do is to setup tracing for it,which implies fetching the root's id. But in btrfs_evict_inode() theroot might be NULL, as implied in the next check that we do inbtrfs_evict_inode().Hence, we either should set the ->root_objectid to 0 in case the root isNULL, or we move tracing setup after checking that the root is notNULL. Setting the rootid to 0 at least gives us the possibility to tracethis call even in the case when the root is NULL, so that's the solutiontaken here.

Description: A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: sch_qfq: Fix NULL deref when deactivating inactive aggregate in qfq_reset`qfq_class->leaf_qdisc->q.qlen > 0` does not imply that the classitself is active.Two qfq_class objects may point to the same leaf_qdisc. This happenswhen:1. one QFQ qdisc is attached to the dev as the root qdisc, and2. another QFQ qdisc is temporarily referenced (e.g., via qdisc_get()/ qdisc_put()) and is pending to be destroyed, as in functiontc_new_tfilter.When packets are enqueued through the root QFQ qdisc, the sharedleaf_qdisc->q.qlen increases. At the same time, the second QFQqdisc triggers qdisc_put and qdisc_destroy: the qdisc entersqfq_reset() with its own q->q.qlen == 0, but its class's leafqdisc->q.qlen > 0. Therefore, the qfq_reset would wrongly deactivatean inactive aggregate and trigger a null-deref in qfq_deactivate_agg:[ 0.903172] BUG: kernel NULL pointer dereference, address: 0000000000000000[ 0.903571] #PF: supervisor write access in kernel mode[ 0.903860] #PF: error_code(0x0002) - not-present page[ 0.904177] PGD 10299b067 P4D 10299b067 PUD 10299c067 PMD 0[ 0.904502] Oops: Oops: 0002 [#1] SMP NOPTI[ 0.904737] CPU: 0 UID: 0 PID: 135 Comm: exploit Not tainted 6.19.0-rc3+ #2 NONE[ 0.905157] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.17.0-0-gb52ca86e094d-prebuilt.qemu.org 04/01/2014[ 0.905754] RIP: 0010:qfq_deactivate_agg (include/linux/list.h:992 (discriminator 2) include/linux/list.h:1006 (discriminator 2) net/sched/sch_qfq.c:1367 (discriminator 2) net/sched/sch_qfq.c:1393 (discriminator 2))[ 0.906046] Code: 0f 84 4d 01 00 00 48 89 70 18 8b 4b 10 48 c7 c2 ff ff ff ff 48 8b 78 08 48 d3 e2 48 21 f2 48 2b 13 48 8b 30 48 d3 ea 8b 4b 18 0Code starting with the faulting instruction=========================================== 0: 0f 84 4d 01 00 00 je 0x153 6: 48 89 70 18 mov %rsi,0x18(%rax) a: 8b 4b 10 mov 0x10(%rbx),%ecx d: 48 c7 c2 ff ff ff ff mov $0xffffffffffffffff,%rdx 14: 48 8b 78 08 mov 0x8(%rax),%rdi 18: 48 d3 e2 shl %cl,%rdx 1b: 48 21 f2 and %rsi,%rdx 1e: 48 2b 13 sub (%rbx),%rdx 21: 48 8b 30 mov (%rax),%rsi 24: 48 d3 ea shr %cl,%rdx 27: 8b 4b 18 mov 0x18(%rbx),%ecx ...[ 0.907095] RSP: 0018:ffffc900004a39a0 EFLAGS: 00010246[ 0.907368] RAX: ffff8881043a0880 RBX: ffff888102953340 RCX: 0000000000000000[ 0.907723] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000[ 0.908100] RBP: ffff888102952180 R08: 0000000000000000 R09: 0000000000000000[ 0.908451] R10: ffff8881043a0000 R11: 0000000000000000 R12: ffff888102952000[ 0.908804] R13: ffff888102952180 R14: ffff8881043a0ad8 R15: ffff8881043a0880[ 0.909179] FS: 000000002a1a0380(0000) GS:ffff888196d8d000(0000) knlGS:0000000000000000[ 0.909572] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 0.909857] CR2: 0000000000000000 CR3: 0000000102993002 CR4: 0000000000772ef0[ 0.910247] PKRU: 55555554[ 0.910391] Call Trace:[ 0.910527] [ 0.910638] qfq_reset_qdisc (net/sched/sch_qfq.c:357 net/sched/sch_qfq.c:1485)[ 0.910826] qdisc_reset (include/linux/skbuff.h:2195 include/linux/skbuff.h:2501 include/linux/skbuff.h:3424 include/linux/skbuff.h:3430 net/sched/sch_generic.c:1036)[ 0.911040] __qdisc_destroy (net/sched/sch_generic.c:1076)[ 0.911236] tc_new_tfilter (net/sched/cls_api.c:2447)[ 0.911447] rtnetlink_rcv_msg (net/core/rtnetlink.c:6958)[ 0.911663] ? __pfx_rtnetlink_rcv_msg (net/core/rtnetlink.c:6861)[ 0.911894] netlink_rcv_skb (net/netlink/af_netlink.c:2550)[ 0.912100] netlink_unicast (net/netlink/af_netlink.c:1319 net/netlink/af_netlink.c:1344)[ 0.912296] ? __alloc_skb (net/core/skbuff.c:706)[ 0.912484] netlink_sendmsg (net/netlink/af---truncated---

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix memory leak in skb_segment_list for GRO packetsWhen skb_segment_list() is called during packet forwarding, it handlespackets that were aggregated by the GRO engine.Historically, the segmentation logic in skb_segment_list assumes thatindividual segments are split from a parent SKB and may need to carrytheir own socket memory accounting. Accordingly, the code transferstruesize from the parent to the newly created segments.Prior to commit ed4cccef64c1 ("gro: fix ownership transfer"), thistruesize subtraction in skb_segment_list() was valid because fragmentsstill carry a reference to the original socket.However, commit ed4cccef64c1 ("gro: fix ownership transfer") changedthis behavior by ensuring that fraglist entries are explicitlyorphaned (skb->sk = NULL) to prevent illegal orphaning later in thestack. This change meant that the entire socket memory charge remainedwith the head SKB, but the corresponding accounting logic inskb_segment_list() was never updated.As a result, the current code unconditionally adds each fragment'struesize to delta_truesize and subtracts it from the parent SKB. Sincethe fragments are no longer charged to the socket, this subtractionresults in an effective under-count of memory when the head is freed.This causes sk_wmem_alloc to remain non-zero, preventing socketdestruction and leading to a persistent memory leak.The leak can be observed via KMEMLEAK when tearing down the networkingenvironment:unreferenced object 0xffff8881e6eb9100 (size 2048): comm "ping", pid 6720, jiffies 4295492526 backtrace: kmem_cache_alloc_noprof+0x5c6/0x800 sk_prot_alloc+0x5b/0x220 sk_alloc+0x35/0xa00 inet6_create.part.0+0x303/0x10d0 __sock_create+0x248/0x640 __sys_socket+0x11b/0x1d0Since skb_segment_list() is exclusively used for SKB_GSO_FRAGLISTpackets constructed by GRO, the truesize adjustment is removed.The call to skb_release_head_state() must be preserved. As documented incommit cf673ed0e057 ("net: fix fraglist segmentation reference countleak"), it is still required to correctly drop references to SKBextensions that may be overwritten during __copy_skb_header().

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

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: detach and close netdevs while handling a resetProtect the reset path from callbacks by setting the netdevs to detachedstate and close any netdevs in UP state until the reset handling hascompleted. During a reset, the driver will de-allocate resources for thevport, and there is no guarantee that those will recover, which is why theexisting vport_ctrl_lock does not provide sufficient protection.idpf_detach_and_close() is called right before reset handling. If thereset handling succeeds, the netdevs state is recovered via call toidpf_attach_and_open(). If the reset handling fails the netdevs remaindown. The detach/down calls are protected with RTNL lock to avoid racingwith callbacks. On the recovery side the attach can be done withoutholding the RTNL lock as there are no callbacks expected at that point,due to detach/close always being done first in that flow.The previous logic restoring the netdevs state based on theIDPF_VPORT_UP_REQUESTED flag in the init task is not needed anymore, hencethe removal of idpf_set_vport_state(). The IDPF_VPORT_UP_REQUESTED isstill being used to restore the state of the netdevs following the reset,but has no use outside of the reset handling flow.idpf_init_hard_reset() is converted to void, since it was used as such andthere is no error handling being done based on its return value.Before this change, invoking hard and soft resets simultaneously willcause the driver to lose the vport state:ip -br a UPecho 1 > /sys/class/net/ens801f0/device/reset& \ethtool -L ens801f0 combined 8ip -br a DOWNip link set upip -br a DOWNAlso in case of a failure in the reset path, the netdev is leftexposed to external callbacks, while vport resources are notinitialized, leading to a crash on subsequent ifup/down:[408471.398966] idpf 0000:83:00.0: HW reset detected[408471.411744] idpf 0000:83:00.0: Device HW Reset initiated[408472.277901] idpf 0000:83:00.0: The driver was unable to contact the device's firmware.

Description: In the Linux kernel, the following vulnerability has been resolved:libceph: make free_choose_arg_map() resilient to partial allocationfree_choose_arg_map() may dereference a NULL pointer if its caller failsafter a partial allocation.For example, in decode_choose_args(), if allocation of arg_map->argsfails, execution jumps to the fail label and free_choose_arg_map() iscalled. Since arg_map->size is updated to a non-zero value before memoryallocation, free_choose_arg_map() will iterate over arg_map->args anddereference a NULL pointer.To prevent this potential NULL pointer dereference and makefree_choose_arg_map() more resilient, add checks for pointers beforeiterating.

Description: In the Linux kernel, the following vulnerability has been resolved:idpf: Fix RSS LUT NULL ptr issue after soft resetDuring soft reset, the RSS LUT is freed and not restored unless theinterface is up. If an ethtool command that accesses the rss lut isattempted immediately after reset, it will result in NULL ptrdereference. Also, there is no need to reset the rss lut if the soft resetdoes not involve queue count change.After soft reset, set the RSS LUT to default values based on the updatedqueue count only if the reset was a result of a queue count change andthe LUT was not configured by the user.

A debug printk() patch found that a refcount is obtained atxdp_convert_md_to_buff() from bpf_prog_test_run_xdp().According to commit ec94670fcb3b ("bpf: Support specifying ingress viaxdp_md context in BPF_PROG_TEST_RUN"), the refcount obtained byxdp_convert_md_to_buff() will be released by xdp_convert_buff_to_md().Therefore, we can consider that the error handling path introduced bycommit 1c1949982524 ("bpf: introduce frags support tobpf_prog_test_run_xdp()") forgot to call xdp_convert_buff_to_md().

This can be triggered by sending H2C_DATA PDUimmediately after the ICREQ/ICRESP handshake, beforesending a CONNECT command or NVMe write command.Attack vectors that trigger NULL pointer dereferences:1. H2C_DATA PDU sent before CONNECT -> both pointers NULL2. H2C_DATA PDU for READ command -> cmd->req.sg allocated, cmd->iov NULL3. H2C_DATA PDU for uninitialized command slot -> both pointers NULLThe fix validates both cmd->req.sg and cmd->iov before callingnvmet_tcp_build_pdu_iovec(). Both checks are required because:- Uninitialized commands: both NULL- READ commands: cmd->req.sg allocated, cmd->iov NULL- WRITE commands: both allocated

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

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix race condition validating r_parent before applying stateAdd validation to ensure the cached parent directory inode matches thedirectory info in MDS replies. This prevents client-side race conditionswhere concurrent operations (e.g. rename) cause r_parent to become stalebetween request initiation and reply processing, which could lead toapplying state changes to incorrect directory inodes.[ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to move CEPH_CAP_PIN reference when r_parent is updated: When the parent directory lock is not held, req->r_parent can become stale and is updated to point to the correct inode. However, the associated CEPH_CAP_PIN reference was not being adjusted. The CEPH_CAP_PIN is a reference on an inode that is tracked for accounting purposes. Moving this pin is important to keep the accounting balanced. When the pin was not moved from the old parent to the new one, it created two problems: The reference on the old, stale parent was never released, causing a reference leak. A reference for the new parent was never acquired, creating the risk of a reference underflow later in ceph_mdsc_release_request(). This patch corrects the logic by releasing the pin from the old parent and acquiring it for the new parent when r_parent is switched. This ensures reference accounting stays balanced. ]

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: ensure no dirty metadata is written back for an fs with errors[BUG]During development of a minor feature (make sure all btrfs_bio::end_io()is called in task context), I noticed a crash in generic/388, wheremetadata writes triggered new works after btrfs_stop_all_workers().It turns out that it can even happen without any code modification, justusing RAID5 for metadata and the same workload from generic/388 is goingto trigger the use-after-free.[CAUSE]If btrfs hits an error, the fs is marked as error, no newtransaction is allowed thus metadata is in a frozen state.But there are some metadata modifications before that error, and they arestill in the btree inode page cache.Since there will be no real transaction commit, all those dirty foliosare just kept as is in the page cache, and they can not be invalidatedby invalidate_inode_pages2() call inside close_ctree(), because they aredirty.And finally after btrfs_stop_all_workers(), we call iput() on btreeinode, which triggers writeback of those dirty metadata.And if the fs is using RAID56 metadata, this will trigger RMW and queuenew works into rmw_workers, which is already stopped, causing warningfrom queue_work() and use-after-free.[FIX]Add a special handling for write_one_eb(), that if the fs is already inan error state, immediately mark the bbio as failure, instead of reallysubmitting them.Then during close_ctree(), iput() will just discard all those dirtytree blocks without really writing them back, thus no more new jobs foralready stopped-and-freed workqueues.The extra discard in write_one_eb() also acts as an extra safenet.E.g. the transaction abort is triggered by some extent/free spacetree corruptions, and since extent/free space tree is already corruptedsome tree blocks may be allocated where they shouldn't be (overwritingexisting tree blocks). In that case writing them back will furthercorrupting the fs.

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.

The code isdesigned to work this way without disabling IRQs and occasionally fail thetrylock with a fallback. However, the SMP=n spinlock implementationassumes spin_trylock() will always succeed, and thus it's normally ano-op. Here the enabled lock debugging catches the problem, but otherwiseit could cause a corruption of the pcp structure.The problem has been introduced by commit 574907741599 ("mm/page_alloc:leave IRQs enabled for per-cpu page allocations"). The pcp locking schemerecognizes the need for disabling IRQs to prevent nesting spin_trylock()sections on SMP=n, but the need to prevent the nesting in spin_lock() hasnot been recognized. Fix it by introducing local wrappers that change thespin_lock() to spin_lock_iqsave() with SMP=n and use them in all placesthat do spin_lock(&pcp->lock).[vbabka@suse.cz: add pcp_ prefix to the spin_lock_irqsave wrappers, per Steven]

Description: In the Linux kernel, the following vulnerability has been resolved:accel/ivpu: Fix locking order in ivpu_job_submitFix deadlock in job submission and abort handling.When a thread aborts currently executing jobs due to a fault,it first locks the global lock protecting submitted_jobs (#1).After the last job is destroyed, it proceeds to release the related contextand locks file_priv (#2). Meanwhile, in the job submission thread,the file_priv lock (#2) is taken first, and then the submitted_jobslock (#1) is obtained when a job is added to the submitted jobs list. CPU0 CPU1 ---- ---- (for example due to a fault) (jobs submissions keep coming) lock(&vdev->submitted_jobs_lock) #1 ivpu_jobs_abort_all() job_destroy() lock(&file_priv->lock) #2 lock(&vdev->submitted_jobs_lock) #1 file_priv_release() lock(&vdev->context_list_lock) lock(&file_priv->lock) #2This order of locking causes a deadlock.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/kmemleak: avoid deadlock by moving pr_warn() outside kmemleak_lockWhen netpoll is enabled, calling pr_warn_once() while holdingkmemleak_lock in mem_pool_alloc() can cause a deadlock due to lockinversion with the netconsole subsystem. This occurs becausepr_warn_once() may trigger netpoll, which eventually leads to__alloc_skb() and back into kmemleak code, attempting to reacquirekmemleak_lock.This is the path for the deadlock.mem_pool_alloc() -> raw_spin_lock_irqsave(&kmemleak_lock, flags); -> pr_warn_once() -> netconsole subsystem -> netpoll -> __alloc_skb -> __create_object -> raw_spin_lock_irqsave(&kmemleak_lock, flags);Fix this by setting a flag and issuing the pr_warn_once() afterkmemleak_lock is released.

Description: In the Linux kernel, the following vulnerability has been resolved:block: Use RCU in blk_mq_[un]quiesce_tagset() instead of set->tag_list_lockblk_mq_{add,del}_queue_tag_set() functions add and remove queues fromtagset, the functions make sure that tagset and queues are marked asshared when two or more queues are attached to the same tagset.Initially a tagset starts as unshared and when the number of addedqueues reaches two, blk_mq_add_queue_tag_set() marks it as shared alongwith all the queues attached to it. When the number of attached queuesdrops to 1 blk_mq_del_queue_tag_set() need to mark both the tagset andthe remaining queues as unshared.Both functions need to freeze current queues in tagset before setting onunsetting BLK_MQ_F_TAG_QUEUE_SHARED flag. While doing so, both functionshold set->tag_list_lock mutex, which makes sense as we do not wantqueues to be added or deleted in the process. This used to work fineuntil commit 98d81f0df70c ("nvme: use blk_mq_[un]quiesce_tagset")made the nvme driver quiesce tagset instead of quiscing individualqueues. blk_mq_quiesce_tagset() does the job and quiesce the queues inset->tag_list while holding set->tag_list_lock also.This results in deadlock between two threads with these stacktraces: __schedule+0x47c/0xbb0 ? timerqueue_add+0x66/0xb0 schedule+0x1c/0xa0 schedule_preempt_disabled+0xa/0x10 __mutex_lock.constprop.0+0x271/0x600 blk_mq_quiesce_tagset+0x25/0xc0 nvme_dev_disable+0x9c/0x250 nvme_timeout+0x1fc/0x520 blk_mq_handle_expired+0x5c/0x90 bt_iter+0x7e/0x90 blk_mq_queue_tag_busy_iter+0x27e/0x550 ? __blk_mq_complete_request_remote+0x10/0x10 ? __blk_mq_complete_request_remote+0x10/0x10 ? __call_rcu_common.constprop.0+0x1c0/0x210 blk_mq_timeout_work+0x12d/0x170 process_one_work+0x12e/0x2d0 worker_thread+0x288/0x3a0 ? rescuer_thread+0x480/0x480 kthread+0xb8/0xe0 ? kthread_park+0x80/0x80 ret_from_fork+0x2d/0x50 ? kthread_park+0x80/0x80 ret_from_fork_asm+0x11/0x20 __schedule+0x47c/0xbb0 ? xas_find+0x161/0x1a0 schedule+0x1c/0xa0 blk_mq_freeze_queue_wait+0x3d/0x70 ? destroy_sched_domains_rcu+0x30/0x30 blk_mq_update_tag_set_shared+0x44/0x80 blk_mq_exit_queue+0x141/0x150 del_gendisk+0x25a/0x2d0 nvme_ns_remove+0xc9/0x170 nvme_remove_namespaces+0xc7/0x100 nvme_remove+0x62/0x150 pci_device_remove+0x23/0x60 device_release_driver_internal+0x159/0x200 unbind_store+0x99/0xa0 kernfs_fop_write_iter+0x112/0x1e0 vfs_write+0x2b1/0x3d0 ksys_write+0x4e/0xb0 do_syscall_64+0x5b/0x160 entry_SYSCALL_64_after_hwframe+0x4b/0x53The top stacktrace is showing nvme_timeout() called to handle nvmecommand timeout. timeout handler is trying to disable the controller andas a first step, it needs to blk_mq_quiesce_tagset() to tell blk-mq notto call queue callback handlers. The thread is stuck waiting forset->tag_list_lock as it tries to walk the queues in set->tag_list.The lock is held by the second thread in the bottom stack which iswaiting for one of queues to be frozen. The queue usage counter willdrop to zero after nvme_timeout() finishes, and this will not happenbecause the thread will wait for this mutex forever.Given that [un]quiescing queue is an operation that does not need tosleep, update blk_mq_[un]quiesce_tagset() to use RCU instead of takingset->tag_list_lock, update blk_mq_{add,del}_queue_tag_set() to use RCUsafe list operations. Also, delete INIT_LIST_HEAD(&q->tag_set_list)in blk_mq_del_queue_tag_set() because we can not re-initialize it whilethe list is being traversed under RCU. The deleted queue will not beadded/deleted to/from a tagset and it will be freed in blk_free_queue()after the end of RCU grace period.

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

Description: In the Linux kernel, the following vulnerability has been resolved:fsnotify: do not generate ACCESS/MODIFY events on child for special filesinotify/fanotify do not allow users with no read access to a file tosubscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow thesame user to subscribe for watching events on children when the userhas access to the parent directory (e.g. /dev).Users with no read access to a file but with read access to its parentdirectory can still stat the file and see if it was accessed/modifiedvia atime/mtime change.The same is not true for special files (e.g. /dev/null). Users will notgenerally observe atime/mtime changes when other users read/write tospecial files, only when someone sets atime/mtime via utimensat().Align fsnotify events with this stat behavior and do not generateACCESS/MODIFY events to parent watchers on read/write of special files.The events are still generated to parent watchers on utimensat().

Description: In the Linux kernel, the following vulnerability has been resolved:ipv4: Fix reference count leak when using error routes with nexthop objectsWhen a nexthop object is deleted, it is marked as dead and thenfib_table_flush() is called to flush all the routes that are using thedead nexthop.The current logic in fib_table_flush() is to only flush error routes(e.g., blackhole) when it is called as part of network namespacedismantle (i.e., with flush_all=true). Therefore, error routes are notflushed when their nexthop object is deleted: # ip link add name dummy1 up type dummy # ip nexthop add id 1 dev dummy1 # ip route add 198.51.100.1/32 nhid 1 # ip route add blackhole 198.51.100.2/32 nhid 1 # ip nexthop del id 1 # ip route show blackhole 198.51.100.2 nhid 1 dev dummy1As such, they keep holding a reference on the nexthop object which inturn holds a reference on the nexthop device, resulting in a referencecount leak: # ip link del dev dummy1 [ 70.516258] unregister_netdevice: waiting for dummy1 to become free. Usage count = 2Fix by flushing error routes when their nexthop is marked as dead.IPv6 does not suffer from this problem.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix deadlock in wait_current_trans() due to ignored transaction typeWhen wait_current_trans() is called during start_transaction(), itcurrently waits for a blocked transaction without considering whetherthe given transaction type actually needs to wait for that particulartransaction state. The btrfs_blocked_trans_types[] array already defineswhich transaction types should wait for which transaction states, butthis check was missing in wait_current_trans().This can lead to a deadlock scenario involving two transactions andpending ordered extents: 1. Transaction A is in TRANS_STATE_COMMIT_DOING state 2. A worker processing an ordered extent calls start_transaction() with TRANS_JOIN 3. join_transaction() returns -EBUSY because Transaction A is in TRANS_STATE_COMMIT_DOING 4. Transaction A moves to TRANS_STATE_UNBLOCKED and completes 5. A new Transaction B is created (TRANS_STATE_RUNNING) 6. The ordered extent from step 2 is added to Transaction B's pending ordered extents 7. Transaction B immediately starts commit by another task and enters TRANS_STATE_COMMIT_START 8. The worker finally reaches wait_current_trans(), sees Transaction B in TRANS_STATE_COMMIT_START (a blocked state), and waits unconditionally 9. However, TRANS_JOIN should NOT wait for TRANS_STATE_COMMIT_START according to btrfs_blocked_trans_types[] 10. Transaction B is waiting for pending ordered extents to complete 11. Deadlock: Transaction B waits for ordered extent, ordered extent waits for Transaction BThis can be illustrated by the following call stacks: CPU0 CPU1 btrfs_finish_ordered_io() start_transaction(TRANS_JOIN) join_transaction() # -EBUSY (Transaction A is # TRANS_STATE_COMMIT_DOING) # Transaction A completes # Transaction B created # ordered extent added to # Transaction B's pending list btrfs_commit_transaction() # Transaction B enters # TRANS_STATE_COMMIT_START # waiting for pending ordered # extents wait_current_trans() # waits for Transaction B # (should not wait!)Task bstore_kv_sync in btrfs_commit_transaction waiting for orderedextents: __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 btrfs_commit_transaction+0xbf7/0xda0 [btrfs] btrfs_sync_file+0x342/0x4d0 [btrfs] __x64_sys_fdatasync+0x4b/0x80 do_syscall_64+0x33/0x40 entry_SYSCALL_64_after_hwframe+0x44/0xa9Task kworker in wait_current_trans waiting for transaction commit: Workqueue: btrfs-syno_nocow btrfs_work_helper [btrfs] __schedule+0x2e7/0x8a0 schedule+0x64/0xe0 wait_current_trans+0xb0/0x110 [btrfs] start_transaction+0x346/0x5b0 [btrfs] btrfs_finish_ordered_io.isra.0+0x49b/0x9c0 [btrfs] btrfs_work_helper+0xe8/0x350 [btrfs] process_one_work+0x1d3/0x3c0 worker_thread+0x4d/0x3e0 kthread+0x12d/0x150 ret_from_fork+0x1f/0x30Fix this by passing the transaction type to wait_current_trans() andchecking btrfs_blocked_trans_types[cur_trans->state] against the giventype before deciding to wait.

Thestate recovery cannot complete until the open() finishes processing thedelegations it was given.The solution is to propagate the existing flags that indicate anon-blocking call to the function pnfs_roc(), so that it knows not towait in this situation.

Description: In the Linux kernel, the following vulnerability has been resolved:NFSD: NFSv4 file creation neglects setting ACLAn NFSv4 client that sets an ACL with a named principal during filecreation retrieves the ACL afterwards, and finds that it is only adefault ACL (based on the mode bits) and not the ACL that wasrequested during file creation. This violates RFC 8881 section6.4.1.3: "the ACL attribute is set as given".The issue occurs in nfsd_create_setattr(), which callsnfsd_attrs_valid() to determine whether to call nfsd_setattr().However, nfsd_attrs_valid() checks only for iattr changes andsecurity labels, but not POSIX ACLs. When only an ACL is present,the function returns false, nfsd_setattr() is skipped, and thePOSIX ACL is never applied to the inode.Subsequently, when the client retrieves the ACL, the server findsno POSIX ACL on the inode and returns one generated from the file'smode bits rather than returning the originally-specified ACL.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: Discard stale CPU state when handling SME trapsThe logic for handling SME traps manipulates saved FPSIMD/SVE/SME stateincorrectly, and a race with preemption can result in a task havingTIF_SME set and TIF_FOREIGN_FPSTATE clear even though the live CPU stateis stale (e.g. with SME traps enabled). This can result in warnings fromdo_sme_acc() where SME traps are not expected while TIF_SME is set:| /* With TIF_SME userspace shouldn't generate any traps */| if (test_and_set_thread_flag(TIF_SME))| WARN_ON(1);This is very similar to the SVE issue we fixed in commit: 751ecf6afd6568ad ("arm64/sve: Discard stale CPU state when handling SVE traps")The race can occur when the SME trap handler is preempted before andafter manipulating the saved FPSIMD/SVE/SME state, starting and ending onthe same CPU, e.g.| void do_sme_acc(unsigned long esr, struct pt_regs *regs)| {| // Trap on CPU 0 with TIF_SME clear, SME traps enabled| // task->fpsimd_cpu is 0.| // per_cpu_ptr(&fpsimd_last_state, 0) is task.|| ...|| // Preempted; migrated from CPU 0 to CPU 1.| // TIF_FOREIGN_FPSTATE is set.|| get_cpu_fpsimd_context();|| /* With TIF_SME userspace shouldn't generate any traps */| if (test_and_set_thread_flag(TIF_SME))| WARN_ON(1);|| if (!test_thread_flag(TIF_FOREIGN_FPSTATE)) {| unsigned long vq_minus_one =| sve_vq_from_vl(task_get_sme_vl(current)) - 1;| sme_set_vq(vq_minus_one);|| fpsimd_bind_task_to_cpu();| }|| put_cpu_fpsimd_context();|| // Preempted; migrated from CPU 1 to CPU 0.| // task->fpsimd_cpu is still 0| // If per_cpu_ptr(&fpsimd_last_state, 0) is still task then:| // - Stale HW state is reused (with SME traps enabled)| // - TIF_FOREIGN_FPSTATE is cleared| // - A return to userspace skips HW state restore| }Fix the case where the state is not live and TIF_FOREIGN_FPSTATE is setby calling fpsimd_flush_task_state() to detach from the saved CPUstate. This ensures that a subsequent context switch will not reuse thestale CPU state, and will instead set TIF_FOREIGN_FPSTATE, forcing thenew state to be reloaded from memory prior to a return to userspace.Note: this was originallly posted as [1].[ Rutland: rewrite commit message ]

Description: In the Linux kernel, the following vulnerability has been resolved:can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leakIn gs_can_open(), the URBs for USB-in transfers are allocated, added to theparent->rx_submitted anchor and submitted. In the complete callbackgs_usb_receive_bulk_callback(), the URB is processed and resubmitted. Ings_can_close() the URBs are freed by callingusb_kill_anchored_urbs(parent->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in gs_can_close().Fix the memory leak by anchoring the URB in thegs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.

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: In the Linux kernel, the following vulnerability has been resolved:usb: xhci: Fix isochronous Ring Underrun/Overrun event handlingThe TRB pointer of these events points at enqueue at the time of erroroccurrence on xHCI 1.1+ HCs or it's NULL on older ones. By the time weare handling the event, a new TD may be queued at this ring position.I can trigger this race by rising interrupt moderation to increase IRQhandling delay. Similar delay may occur naturally due to system load.If this ever happens after a Missed Service Error, missed TDs will beskipped and the new TD processed as if it matched the event. It couldbe given back prematurely, risking data loss or buffer UAF by the xHC.Don't complete TDs on xrun events and don't warn if queued TDs don'tmatch the event's TRB pointer, which can be NULL or a link/no-op TRB.Don't warn if there are no queued TDs at all.Now that it's safe, also handle xrun events if the skip flag is clear.This ensures completion of any TD stuck in 'error mid TD' state rightbefore the xrun event, which could happen if a driver submits a finitenumber of URBs to a buggy HC and then an error occurs on the last TD.

Description: In the Linux kernel, the following vulnerability has been resolved:ipv6: fix a BUG in rt6_get_pcpu_route() under PREEMPT_RTOn PREEMPT_RT kernels, after rt6_get_pcpu_route() returns NULL, thecurrent task can be preempted. Another task running on the same CPUmay then execute rt6_make_pcpu_route() and successfully install apcpu_rt entry. When the first task resumes execution, its cmpxchg()in rt6_make_pcpu_route() will fail because rt6i_pcpu is no longerNULL, triggering the BUG_ON(prev). It's easy to reproduce it by addingmdelay() after rt6_get_pcpu_route().Using preempt_disable/enable is not appropriate here becauseip6_rt_pcpu_alloc() may sleep.Fix this by handling the cmpxchg() failure gracefully on PREEMPT_RT:free our allocation and return the existing pcpu_rt installed byanother task. The BUG_ON is replaced by WARN_ON_ONCE for non-PREEMPT_RTkernels where such races should not occur.

Description: When passing data to the b64decode(), standard_b64decode(), and urlsafe_b64decode() functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. This behavior matches what is recommended in earlier base64 RFCs, but newer RFCs now recommend either dropping characters outside the specified base64 alphabet or raising an error. The old behavior has the possibility of causing data integrity issues.This behavior can only be insecure if your application uses an alternate base64 alphabet (without "+/"). If your application does not use the "altchars" parameter or the urlsafe_b64decode() function, then your application does not use an alternative base64 alphabet.The attached patches DOES NOT make the base64-decode behavior raise an error, as this would be a change in behavior and break existing programs. Instead, the patch deprecates the behavior which will be replaced with the newly recommended behavior in a future version of Python. Users are recommended to mitigate by verifying user-controlled inputs match the base64 alphabet they are expecting or verify that their application would not be affected if the b64decode() functions accepted "+" or "/" outside of altchars.

Description: In the Linux kernel, the following vulnerability has been resolved:efivarfs: Fix memory leak of efivarfs_fs_info in fs_context error pathsWhen processing mount options, efivarfs allocates efivarfs_fs_info (sfi)early in fs_context initialization. However, sfi is associated with thesuperblock and typically freed when the superblock is destroyed. If thefs_context is released (final put) before fill_super is called-such ason error paths or during reconfiguration-the sfi structure would leak,as ownership never transfers to the superblock.Implement the .free callback in efivarfs_context_ops to ensure anyallocated sfi is properly freed if the fs_context is torn down beforefill_super, preventing this memory leak.

But there are cases where we could avoid revalidation.Consider:1 input -> j2 -> j32 input -> j2 -> j33 input -> j1 -> j2 -> j3Then the second rule does not need to revalidate j2, and, by extension j3,because this was already checked during validation of the first rule.We need to validate it only for rule 3.This is needed because chain loop detection also ensures we do not exceedthe jump stack: Just because we know that j2 is cycle free, its last jumpmight now exceed the allowed stack size. We also need to update allreachable chains with the new largest observed call depth.Care has to be taken to revalidate even if the chain depth won't be anissue: chain validation also ensures that expressions are not called frominvalid base chains. For example, the masquerade expression can only becalled from NAT postrouting base chains.Therefore we also need to keep record of the base chain context (type,hooknum) and revalidate if the chain becomes reachable from a differenthook location.

The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all."

Description: A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to free the allocated buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system memory and terminate the xmllint process, creating a denial-of-service condition on the local system.

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