Description: Cockpit's remote login feature passes user-supplied hostnames and usernames from the web interface to the SSH client without validation or sanitization. An attacker with network access to the Cockpit web service can craft a single HTTP request to the login endpoint that injects malicious SSH options or shell commands, achieving code execution on the Cockpit host without valid credentials. The injection occurs during the authentication flow before any credential verification takes place, meaning no login is required to exploit the vulnerability.

Description: Rollup is a module bundler for JavaScript. Versions prior to 2.80.0, 3.30.0, and 4.59.0 of the Rollup module bundler (specifically v4.x and present in current source) is vulnerable to an Arbitrary File Write via Path Traversal. Insecure file name sanitization in the core engine allows an attacker to control output filenames (e.g., via CLI named inputs, manual chunk aliases, or malicious plugins) and use traversal sequences (`../`) to overwrite files anywhere on the host filesystem that the build process has permissions for. This can lead to persistent Remote Code Execution (RCE) by overwriting critical system or user configuration files. Versions 2.80.0, 3.30.0, and 4.59.0 contain a patch for the issue.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. In versions 1.6.36 through 1.6.55, an out-of-bounds read and write exists in libpng's ARM/AArch64 Neon-optimized palette expansion path. When expanding 8-bit paletted rows to RGB or RGBA, the Neon loop processes a final partial chunk without verifying that enough input pixels remain. Because the implementation works backward from the end of the row, the final iteration dereferences pointers before the start of the row buffer (OOB read) and writes expanded pixel data to the same underflowed positions (OOB write). This is reachable via normal decoding of attacker-controlled PNG input if Neon is enabled. Version 1.6.56 fixes the issue.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. In versions 1.2.1 through 1.6.55, `png_set_tRNS` and `png_set_PLTE` each alias a heap-allocated buffer between `png_struct` and `png_info`, sharing a single allocation across two structs with independent lifetimes. The `trans_alpha` aliasing has been present since at least libpng 1.0, and the `palette` aliasing since at least 1.2.1. Both affect all prior release lines `png_set_tRNS` sets `png_ptr->trans_alpha = info_ptr->trans_alpha` (256-byte buffer) and `png_set_PLTE` sets `info_ptr->palette = png_ptr->palette` (768-byte buffer). In both cases, calling `png_free_data` (with `PNG_FREE_TRNS` or `PNG_FREE_PLTE`) frees the buffer through `info_ptr` while the corresponding `png_ptr` pointer remains dangling. Subsequent row-transform functions dereference and, in some code paths, write to the freed memory. A second call to `png_set_tRNS` or `png_set_PLTE` has the same effect, because both functions call `png_free_data` internally before reallocating the `info_ptr` buffer. Version 1.6.56 fixes the issue.

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

Description: 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: runc is a CLI tool for spawning and running containers according to the OCI specification. Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting `/dev/pts/$n` to `/dev/console` inside the container, an attacker can trick runc into bind-mounting paths which would normally be made read-only or be masked onto a path that the attacker can write to. This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target (namely, the bind-mount of `/dev/pts/$n` to `/dev/console` as configured for all containers that allocate a console). This happens after `pivot_root(2)`, so this cannot be used to write to host files directly -- however, as with CVE-2025-31133, this can load to denial of service of the host or a container breakout by providing the attacker with a writable copy of `/proc/sysrq-trigger` or `/proc/sys/kernel/core_pattern` (respectively).

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7, 1.3.2 and 1.4.0-rc.2, an attacker can trick runc into misdirecting writes to /proc to other procfs files through the use of a racing container with shared mounts (we have also verified this attack is possible to exploit using a standard Dockerfile with docker buildx build as that also permits triggering parallel execution of containers with custom shared mounts configured). This redirect could be through symbolic links in a tmpfs or theoretically other methods such as regular bind-mounts. While similar, the mitigation applied for the related CVE, CVE-2019-19921, was fairly limited and effectively only caused runc to verify that when LSM labels are written they are actually procfs files.

Instead, the current code does the opposite: it skips inactiveelements and processes active ones.Compare the non-catchall activate callback, which is correct: nft_mapelem_activate(): if (nft_set_elem_active(ext, iter->genmask)) return 0; /* skip active, process inactive */With the buggy catchall version: nft_map_catchall_activate(): if (!nft_set_elem_active(ext, genmask)) continue; /* skip inactive, process active */The consequence is that when a DELSET operation is aborted,nft_setelem_data_activate() is never called for the catchall element.For NFT_GOTO verdict elements, this means nft_data_hold() is nevercalled to restore the chain->use reference count. Each abort cyclepermanently decrements chain->use. Once chain->use reaches zero,DELCHAIN succeeds and frees the chain while catchall verdict elementsstill reference it, resulting in a use-after-free.This is exploitable for local privilege escalation from an unprivilegeduser via user namespaces + nftables on distributions that enableCONFIG_USER_NS and CONFIG_NF_TABLES.Fix by removing the negation so the check matches nft_mapelem_activate():skip active elements, process inactive ones.

A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.

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: ipmi-oem in FreeIPMI before 1.16.17 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Three subcommands were found to have exploitable buffer overflows on response messages. They are: "ipmi-oem dell get-last-post-code - get the last POST code and string describing the error on some Dell servers," "ipmi-oem supermicro extra-firmware-info - get extra firmware info on Supermicro servers," and "ipmi-oem wistron read-proprietary-string - read a proprietary string on Wistron servers."

Description: The NPM package `micromatch` prior to 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8.

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: libcurl can in some circumstances reuse the wrong connection when asked to doan Negotiate-authenticated HTTP or HTTPS request.libcurl features a pool of recent connections so that subsequent requests canreuse an existing connection to avoid overhead.When reusing a connection a range of criterion must first be met. Due to alogical error in the code, a request that was issued by an application couldwrongfully reuse an existing connection to the same server that wasauthenticated using different credentials. One underlying reason being thatNegotiate sometimes authenticates *connections* and not *requests*, contraryto how HTTP is designed to work.An application that allows Negotiate authentication to a server (that respondswanting Negotiate) with `user1:password1` and then does another operation tothe same server also using Negotiate but with `user2:password2` (while theprevious connection is still alive) - the second request wrongly reused thesame connection and since it then sees that the Negotiate negotiation isalready made, it just sends the request over that connection thinking it usesthe user2 credentials when it is in fact still using the connectionauthenticated for user1...The set of authentication methods to use is set with `CURLOPT_HTTPAUTH`.Applications can disable libcurl's reuse of connections and thus mitigate thisproblem, by using one of the following libcurl options to alter howconnections are or are not reused: `CURLOPT_FRESH_CONNECT`,`CURLOPT_MAXCONNECTS` and `CURLMOPT_MAX_HOST_CONNECTIONS` (if using thecurl_multi API).

Description: minimatch is a minimal matching utility for converting glob expressions into JavaScript RegExp objects. Versions 10.2.0 and below are vulnerable to Regular Expression Denial of Service (ReDoS) when a glob pattern contains many consecutive * wildcards followed by a literal character that doesn't appear in the test string. Each * compiles to a separate [^/]*? regex group, and when the match fails, V8's regex engine backtracks exponentially across all possible splits. The time complexity is O(4^N) where N is the number of * characters. With N=15, a single minimatch() call takes ~2 seconds. With N=34, it hangs effectively forever. Any application that passes user-controlled strings to minimatch() as the pattern argument is vulnerable to DoS. This issue has been fixed in version 10.2.1.

They might be called internally by the library when it detects the situation that is subject to connection error. Due to the missing internal state validation, the library keeps reading the rest of the data after one of those APIs is called. Then receiving a malformed frame that causes FRAME_SIZE_ERROR causes assertion failure. nghttp2 v1.68.1 adds missing state validation to avoid assertion failure. No known workarounds are available.

Prior to version 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4, nested `*()` extglobs produce regexps with nested unbounded quantifiers (e.g. `(?:(?:a|b)*)*`), which exhibit catastrophic backtracking in V8. With a 12-byte pattern `*(*(*(a|b)))` and an 18-byte non-matching input, `minimatch()` stalls for over 7 seconds. Adding a single nesting level or a few input characters pushes this to minutes. This is the most severe finding: it is triggered by the default `minimatch()` API with no special options, and the minimum viable pattern is only 12 bytes. The same issue affects `+()` extglobs equally. Versions 10.2.3, 9.0.7, 8.0.6, 7.4.8, 6.2.2, 5.1.8, 4.2.5, and 3.1.4 fix the issue.

Description: pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the `pyasn1` library is vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested `SEQUENCE` (`0x30`) or `SET` (`0x31`) tags with "Indefinite Length" (`0x80`) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a `RecursionError` or consumes all available memory (OOM), crashing the host application. This is a distinct vulnerability from CVE-2026-23490 (which addressed integer overflows in OID decoding). The fix for CVE-2026-23490 (`MAX_OID_ARC_CONTINUATION_OCTETS`) does not mitigate this recursion issue. Version 0.6.3 fixes this specific issue.

A request with a large or unbounded Range header (e.g. `bytes=0-`) could cause the server to allocate memory proportional to the file size, possibly resulting in a DoS vulnerability through memory exhaustion. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Description: Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. `1e10000`), which `BigDecimal` expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Description: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#delete_prefixed` passes blob keys directly to `Dir.glob` without escaping glob metacharacters. If a blob key contains attacker-controlled input or custom-generated keys with glob metacharacters, it may be possible to delete unintended files from the storage directory. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Description: BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. Prior to version 0.28.1, insufficient validation of Git URL fragment subdir components may allow access to files outside the checked-out Git repository root. Possible access is limited to files on the same mounted filesystem. The issue has been fixed in version v0.28.1 The issue affects only builds that use Git URLs with a subpath component. As a workaround, avoid building Dockerfiles from untrusted sources or using the subdir component from an untrusted Git repository where the subdir component could point to a symlink.

Description: Issue summary: Converting an excessively large OCTET STRING value toa hexadecimal string leads to a heap buffer overflow on 32 bit platforms.Impact summary: A heap buffer overflow may lead to a crash or possiblyan attacker controlled code execution or other undefined behavior.If an attacker can supply a crafted X.509 certificate with an excessivelylarge OCTET STRING value in extensions such as the Subject Key Identifier(SKID) or Authority Key Identifier (AKID) which are being converted to hex,the size of the buffer needed for the result is calculated as multiplicationof the input length by 3. On 32 bit platforms, this multiplication may overflowresulting in the allocation of a smaller buffer and a heap buffer overflow.Applications and services that print or log contents of untrusted X.509certificates are vulnerable to this issue. As the certificates would haveto have sizes of over 1 Gigabyte, printing or logging such certificatesis a fairly unlikely operation and only 32 bit platforms are affected,this issue was assigned Low severity.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary.

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:rxrpc: Fix recvmsg() unconditional requeueIf rxrpc_recvmsg() fails because MSG_DONTWAIT was specified but the call atthe front of the recvmsg queue already has its mutex locked, it requeuesthe call - whether or not the call is already queued. The call may be onthe queue because MSG_PEEK was also passed and so the call was not dequeuedor because the I/O thread requeued it.The unconditional requeue may then corrupt the recvmsg queue, leading tothings like UAFs or refcount underruns.Fix this by only requeuing the call if it isn't already on the queue - andmoving it to the front if it is already queued. If we don't queue it, wehave to put the ref we obtained by dequeuing it.Also, MSG_PEEK doesn't dequeue the call so shouldn't callrxrpc_notify_socket() for the call if we didn't use up all the data on thequeue, so fix that also.

Description: In the Linux kernel, the following vulnerability has been resolved:net/sched: Enforce that teql can only be used as root qdiscDesign intent of teql is that it is only supposed to be used as root qdisc.We need to check for that constraint.Although not important, I will describe the scenario that unearthed thisissue for the curious.GangMin Kim managed to concot a scenario as follows:ROOT qdisc 1:0 (QFQ) ├── class 1:1 (weight=15, lmax=16384) netem with delay 6.4s ── class 1:2 (weight=1, lmax=1514) teqlGangMin sends a packet which is enqueued to 1:1 (netem).Any invocation of dequeue by QFQ from this class will not return a packetuntil after 6.4s. In the meantime, a second packet is sent and it lands on1:2. teql's enqueue will return success and this will activate class 1:2.Main issue is that teql only updates the parent visible qlen (sch->q.qlen)at dequeue. Since QFQ will only call dequeue if peek succeeds (and teql'speek always returns NULL), dequeue will never be called and thus the qlenwill remain as 0. With that in mind, when GangMin updates 1:2's lmax value,the qfq_change_class calls qfq_deact_rm_from_agg. Since the child qdisc'sqlen was not incremented, qfq fails to deactivate the class, but stillfrees its pointers from the aggregate. So when the first packet isrescheduled after 6.4 seconds (netem's delay), a dangling pointer isaccessed causing GangMin's causing a UAF.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/shmem, swap: fix race of truncate and swap entry splitThe helper for shmem swap freeing is not handling the order of swapentries correctly. It uses xa_cmpxchg_irq to erase the swap entry, but itgets the entry order before that using xa_get_order without lockprotection, and it may get an outdated order value if the entry is splitor changed in other ways after the xa_get_order and before thexa_cmpxchg_irq.And besides, the order could grow and be larger than expected, and causetruncation to erase data beyond the end border. For example, if thetarget entry and following entries are swapped in or freed, then a largefolio was added in place and swapped out, using the same entry, thexa_cmpxchg_irq will still succeed, it's very unlikely to happen though.To fix that, open code the Xarray cmpxchg and put the order retrieval andvalue checking in the same critical section. Also, ensure the order won'texceed the end border, skip it if the entry goes across the border.Skipping large swap entries crosses the end border is safe here. Shmemtruncate iterates the range twice, in the first iteration,find_lock_entries already filtered such entries, and shmem will swapin theentries that cross the end border and partially truncate the folio (splitthe folio or at least zero part of it). So in the second loop here, if wesee a swap entry that crosses the end order, it must at least have itscontent erased already.I observed random swapoff hangs and kernel panics when stress testingZSWAP with shmem. After applying this patch, all problems are gone.

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

Description: In the Linux kernel, the following vulnerability has been resolved:bridge: cfm: Fix race condition in peer_mep deletionWhen a peer MEP is being deleted, cancel_delayed_work_sync() is calledon ccm_rx_dwork before freeing. However, br_cfm_frame_rx() runs insoftirq context under rcu_read_lock (without RTNL) and can re-scheduleccm_rx_dwork via ccm_rx_timer_start() between cancel_delayed_work_sync()returning and kfree_rcu() being called.The following is a simple race scenario: cpu0 cpu1mep_delete_implementation() cancel_delayed_work_sync(ccm_rx_dwork); br_cfm_frame_rx() // peer_mep still in hlist if (peer_mep->ccm_defect) ccm_rx_timer_start() queue_delayed_work(ccm_rx_dwork) hlist_del_rcu(&peer_mep->head); kfree_rcu(peer_mep, rcu); ccm_rx_work_expired() // on freed peer_mepTo prevent this, cancel_delayed_work_sync() is replaced withdisable_delayed_work_sync() in both peer MEP deletion paths, sothat subsequent queue_delayed_work() calls from br_cfm_frame_rx()are silently rejected.The cc_peer_disable() helper retains cancel_delayed_work_sync()because it is also used for the CC enable/disable toggle path wherethe work must remain re-schedulable.

Description: LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.

In TDXenvironments with remote attestation, quotes are not considered private,and can be forwarded to an attestation server.Catch scenarios where the host specifies a response length larger thanthe guest's allocation, or otherwise races modifying the response whilethe guest consumes it.This prevents contents beyond the pages allocated for `quote_buf`(up to TSM_REPORT_OUTBLOB_MAX) from being read out to guest userspace,and possibly forwarded in attestation requests.Recall that some deployments want per-container configs-tsm-reportinterfaces, so the leak may cross container protection boundaries, notjust local root.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix undefined behavior in interpreter sdiv/smod for INT_MINThe BPF interpreter's signed 32-bit division and modulo handlers usethe kernel abs() macro on s32 operands. The abs() macro documentation(include/linux/math.h) explicitly states the result is undefined whenthe input is the type minimum. When DST contains S32_MIN (0x80000000),abs((s32)DST) triggers undefined behavior and returns S32_MIN unchangedon arm64/x86. This value is then sign-extended to u64 as0xFFFFFFFF80000000, causing do_div() to compute the wrong result.The verifier's abstract interpretation (scalar32_min_max_sdiv) computesthe mathematically correct result for range tracking, creating averifier/interpreter mismatch that can be exploited for out-of-boundsmap value access.Introduce abs_s32() which handles S32_MIN correctly by casting to u32before negating, avoiding signed overflow entirely. Replace all 8abs((s32)...) call sites in the interpreter's sdiv32/smod32 handlers.s32 is the only affected case -- the s64 division/modulo handlers donot use abs().

Description: In the Linux kernel, the following vulnerability has been resolved:net/tls: fix use-after-free in -EBUSY error path of tls_do_encryptionThe -EBUSY handling in tls_do_encryption(), introduced by commit859054147318 ("net: tls: handle backlogging of crypto requests"), hasa use-after-free due to double cleanup of encrypt_pending and thescatterlist entry.When crypto_aead_encrypt() returns -EBUSY, the request is enqueued tothe cryptd backlog and the async callback tls_encrypt_done() will beinvoked upon completion. That callback unconditionally restores thescatterlist entry (sge->offset, sge->length) and decrementsctx->encrypt_pending. However, if tls_encrypt_async_wait() returns anerror, the synchronous error path in tls_do_encryption() performs thesame cleanup again, double-decrementing encrypt_pending anddouble-restoring the scatterlist.The double-decrement corrupts the encrypt_pending sentinel (initializedto 1), making tls_encrypt_async_wait() permanently skip the wait forpending async callbacks. A subsequent sendmsg can then free thetls_rec via bpf_exec_tx_verdict() while a cryptd callback is stillpending, resulting in a use-after-free when the callback fires on thefreed record.Fix this by skipping the synchronous cleanup when the -EBUSY asyncwait returns an error, since the callback has already handledencrypt_pending and sge restoration.

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

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

Description: In the Linux kernel, the following vulnerability has been resolved: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: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:vsock/virtio: Coalesce only linear skbvsock/virtio common tries to coalesce buffers in rx queue: if a linear skb(with a spare tail room) is followed by a small skb (length limited byGOOD_COPY_LEN = 128), an attempt is made to join them.Since the introduction of MSG_ZEROCOPY support, assumption that a small skbwill always be linear is incorrect. In the zerocopy case, data is lost andthe linear skb is appended with uninitialized kernel memory.Of all 3 supported virtio-based transports, only loopback-transport isaffected. G2H virtio-transport rx queue operates on explicitly linear skbs;see virtio_vsock_alloc_linear_skb() in virtio_vsock_rx_fill(). H2Gvhost-transport may allocate non-linear skbs, but only for sizes that arenot considered for coalescence; see PAGE_ALLOC_COSTLY_ORDER invirtio_vsock_alloc_skb().Ensure only linear skbs are coalesced. Note that skb_tailroom(last_skb) > 0guarantees last_skb is linear.

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

Description: Rustix is a set of safe Rust bindings to POSIX-ish APIs. When using `rustix::fs::Dir` using the `linux_raw` backend, it's possible for the iterator to "get stuck" when an IO error is encountered. Combined with a memory over-allocation issue in `rustix::fs::Dir::read_more`, this can cause quick and unbounded memory explosion (gigabytes in a few seconds if used on a hot path) and eventually lead to an OOM crash of the application. The symptoms were initially discovered in https://github.com/imsnif/bandwhich/issues/284. That post has lots of details of our investigation. Full details can be read on the GHSA-c827-hfw6-qwvm repo advisory. If a program tries to access a directory with its file descriptor after the file has been unlinked (or any other action that leaves the `Dir` iterator in the stuck state), and the implementation does not break after seeing an error, it can cause a memory explosion. As an example, Linux's various virtual file systems (e.g. `/proc`, `/sys`) can contain directories that spontaneously pop in and out of existence. Attempting to iterate over them using `rustix::fs::Dir` directly or indirectly (e.g. with the `procfs` crate) can trigger this fault condition if the implementation decides to continue on errors. An attacker knowledgeable about the implementation details of a vulnerable target can therefore try to trigger this fault condition via any one or a combination of several available APIs. If successful, the application host will quickly run out of memory, after which the application will likely be terminated by an OOM killer, leading to denial of service. This issue has been addressed in release versions 0.35.15, 0.36.16, 0.37.25, and 0.38.19. Users are advised to upgrade. There are no known workarounds for this issue.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: prevent A-MSDU attacks in mesh networksThis patch is a mitigation to prevent the A-MSDU spoofing vulnerabilityfor mesh networks. The initial update to the IEEE 802.11 standard, inresponse to the FragAttacks, missed this case (CVE-2025-27558). It canbe considered a variant of CVE-2020-24588 but for mesh networks.This patch tries to detect if a standard MSDU was turned into an A-MSDUby an adversary. This is done by parsing a received A-MSDU as a standardMSDU, calculating the length of the Mesh Control header, and seeing ifthe 6 bytes after this header equal the start of an rfc1042 header. Ifequal, this is a strong indication of an ongoing attack attempt.This defense was tested with mac80211_hwsim against a mesh network thatuses an empty Mesh Address Extension field, i.e., when four addressesare used, and when using a 12-byte Mesh Address Extension field, i.e.,when six addresses are used. Functionality of normal MSDUs and A-MSDUswas also tested, and confirmed working, when using both an empty and12-byte Mesh Address Extension field.It was also tested with mac80211_hwsim that A-MSDU attacks in non-meshnetworks keep being detected and prevented.Note that the vulnerability being patched, and the defense beingimplemented, was also discussed in the following paper and in thefollowing IEEE 802.11 presentation:https://papers.mathyvanhoef.com/wisec2025.pdfhttps://mentor.ieee.org/802.11/dcn/25/11-25-0949-00-000m-a-msdu-mesh-spoof-protection.docx

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).

Description: In the Linux kernel, the following vulnerability has been resolved:vsock/virtio: cap TX credit to local buffer sizeThe virtio transports derives its TX credit directly from peer_buf_alloc,which is set from the remote endpoint's SO_VM_SOCKETS_BUFFER_SIZE value.On the host side this means that the amount of data we are willing toqueue for a connection is scaled by a guest-chosen buffer size, ratherthan the host's own vsock configuration. A malicious guest can advertisea large buffer and read slowly, causing the host to allocate acorrespondingly large amount of sk_buff memory.The same thing would happen in the guest with a malicious host, sincevirtio transports share the same code base.Introduce a small helper, virtio_transport_tx_buf_size(), thatreturns min(peer_buf_alloc, buf_alloc), and use it wherever we consumepeer_buf_alloc.This ensures the effective TX window is bounded by both the peer'sadvertised buffer and our own buf_alloc (already clamped tobuffer_max_size via SO_VM_SOCKETS_BUFFER_MAX_SIZE), so a remote peercannot force the other to queue more data than allowed by its ownvsock settings.On an unpatched Ubuntu 22.04 host (~64 GiB RAM), running a PoC with32 guest vsock connections advertising 2 GiB each and reading slowlydrove Slab/SUnreclaim from ~0.5 GiB to ~57 GiB; the system onlyrecovered after killing the QEMU process. That said, if QEMU memory islimited with cgroups, the maximum memory used will be limited.With this patch applied: Before: MemFree: ~61.6 GiB Slab: ~142 MiB SUnreclaim: ~117 MiB After 32 high-credit connections: MemFree: ~61.5 GiB Slab: ~178 MiB SUnreclaim: ~152 MiBOnly ~35 MiB increase in Slab/SUnreclaim, no host OOM, and the guestremains responsive.Compatibility with non-virtio transports: - VMCI uses the AF_VSOCK buffer knobs to size its queue pairs per socket based on the local vsk->buffer_* values; the remote side cannot enlarge those queues beyond what the local endpoint configured. - Hyper-V's vsock transport uses fixed-size VMBus ring buffers and an MTU bound; there is no peer-controlled credit field comparable to peer_buf_alloc, and the remote endpoint cannot drive in-flight kernel memory above those ring sizes. - The loopback path reuses virtio_transport_common.c, so it naturally follows the same semantics as the virtio transport.This change is limited to virtio_transport_common.c and thus affectsvirtio-vsock, vhost-vsock, and loopback, bringing them in line with the"remote window intersected with local policy" behaviour that VMCI andHyper-V already effectively have.[Stefano: small adjustments after changing the previous patch][Stefano: tweak the commit message]

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

When called frommesh_rx_csa_frame(), the parsed action-frame elements may not contain aMesh Configuration IE, leaving ie->mesh_config NULL and triggering akernel NULL pointer dereference.The other two callers are already safe: - ieee80211_mesh_rx_bcn_presp() checks !elems->mesh_config before calling mesh_matches_local() - mesh_plink_get_event() is only reached through mesh_process_plink_frame(), which checks !elems->mesh_config, toomesh_rx_csa_frame() is the only caller that passes raw parsed elementsto mesh_matches_local() without guarding mesh_config.

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: Issue summary: An uncommon configuration of clients performing DANE TLSA-basedserver authentication, when paired with uncommon server DANE TLSA records, mayresult in a use-after-free and/or double-free on the client side.Impact summary: A use after free can have a range of potential consequencessuch as the corruption of valid data, crashes or execution of arbitrary code.However, the issue only affects clients that make use of TLSA records with boththe PKIX-TA(0/PKIX-EE(1) certificate usages and the DANE-TA(2) certificateusage.By far the most common deployment of DANE is in SMTP MTAs for which RFC7672recommends that clients treat as 'unusable' any TLSA records that have the PKIXcertificate usages. These SMTP (or other similar) clients are not vulnerableto this issue. Conversely, any clients that support only the PKIX usages, andignore the DANE-TA(2) usage are also not vulnerable.The client would also need to be communicating with a server that publishes aTLSA RRset with both types of TLSA records.No FIPS modules are affected by this issue, the problem code is outside theFIPS module boundary.

Description: Issue summary: Applications using RSASVE key encapsulation to establisha secret encryption key can send contents of an uninitialized memory buffer toa malicious peer.Impact summary: The uninitialized buffer might contain sensitive data from theprevious execution of the application process which leads to sensitive dataleakage to an attacker.RSA_public_encrypt() returns the number of bytes written on success and -1on error. The affected code tests only whether the return value is non-zero.As a result, if RSA encryption fails, encapsulation can still return success tothe caller, set the output lengths, and leave the caller to use the contents ofthe ciphertext buffer as if a valid KEM ciphertext had been produced.If applications use EVP_PKEY_encapsulate() with RSA/RSASVE on anattacker-supplied invalid RSA public key without first validating that key,then this may cause stale or uninitialized contents of the caller-providedciphertext buffer to be disclosed to the attacker in place of the KEMciphertext.As a workaround calling EVP_PKEY_public_check() orEVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will mitigatethe issue.The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue.

Description: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#path_for` does not validate that the resolved filesystem path remains within the storage root directory. If a blob key containing path traversal sequences (e.g. `../`) is used, it could allow reading, writing, or deleting arbitrary files on the server. Blob keys are expected to be trusted strings, but some applications could be passing user input as keys and would be affected. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Fix a UAF issue in bpf_trampoline_link_cgroup_shimThe root cause of this bug is that when 'bpf_link_put' reduces therefcount of 'shim_link->link.link' to zero, the resource is consideredreleased but may still be referenced via 'tr->progs_hlist' in'cgroup_shim_find'. The actual cleanup of 'tr->progs_hlist' in'bpf_shim_tramp_link_release' is deferred. During this window, anotherprocess can cause a use-after-free via 'bpf_trampoline_link_cgroup_shim'.Based on Martin KaFai Lau's suggestions, I have created a simple patch.To fix this: Add an atomic non-zero check in 'bpf_trampoline_link_cgroup_shim'. Only increment the refcount if it is not already zero.Testing: I verified the fix by adding a delay in 'bpf_shim_tramp_link_release' to make the bug easier to trigger:static void bpf_shim_tramp_link_release(struct bpf_link *link){ /* ... */ if (!shim_link->trampoline) return;+ msleep(100); WARN_ON_ONCE(bpf_trampoline_unlink_prog(&shim_link->link, shim_link->trampoline, NULL)); bpf_trampoline_put(shim_link->trampoline);}Before the patch, running a PoC easily reproduced the crash(almost 100%)with a call trace similar to KaiyanM's report.After the patch, the bug no longer occurs even after millions ofiterations.

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

Description: In the Linux kernel, the following vulnerability has been resolved:cxl/port: Fix use after free of parent_port in cxl_detach_ep()cxl_detach_ep() is called during bottom-up removal when all CXL memorydevices beneath a switch port have been removed. For each port in thehierarchy it locks both the port and its parent, removes the endpoint,and if the port is now empty, marks it dead and unregisters the portby calling delete_switch_port(). There are two places during this workwhere the parent_port may be used after freeing:First, a concurrent detach may have already processed a port by thetime a second worker finds it via bus_find_device(). Without pinningparent_port, it may already be freed when we discover port->dead andattempt to unlock the parent_port. In a production kernel that's asilent memory corruption, with lock debug, it looks like this:[]DEBUG_LOCKS_WARN_ON(__owner_task(owner) != get_current())[]WARNING: kernel/locking/mutex.c:949 at __mutex_unlock_slowpath+0x1ee/0x310[]Call Trace:[]mutex_unlock+0xd/0x20[]cxl_detach_ep+0x180/0x400 [cxl_core][]devm_action_release+0x10/0x20[]devres_release_all+0xa8/0xe0[]device_unbind_cleanup+0xd/0xa0[]really_probe+0x1a6/0x3e0Second, delete_switch_port() releases three devm actions registeredagainst parent_port. The last of those is unregister_port() and itcalls device_unregister() on the child port, which can cascade. Ifparent_port is now also empty the device core may unregister and freeit too. So by the time delete_switch_port() returns, parent_port maybe free, and the subsequent device_unlock(&parent_port->dev) operateson freed memory. The kernel log looks same as above, with a differentoffset in cxl_detach_ep().Both of these issues stem from the absence of a lifetime guaranteebetween a child port and its parent port.Establish a lifetime rule for ports: child ports hold a reference totheir parent device until release. Take the reference when the portis allocated and drop it when released. This ensures the parent isvalid for the full lifetime of the child and eliminates the use afterfree window in cxl_detach_ep().This is easily reproduced with a reload of cxl_acpi in QEMU with CXLdevices present.

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:uacce: implement mremap in uacce_vm_ops to return -EPERMThe current uacce_vm_ops does not support the mremap operation ofvm_operations_struct. Implement .mremap to return -EPERM to remindusers.The reason we need to explicitly disable mremap is that when thedriver does not implement .mremap, it uses the default mremapmethod. This could lead to a risk scenario:An application might first mmap address p1, then mremap to p2,followed by munmap(p1), and finally munmap(p2). Since the defaultmremap copies the original vma's vm_private_data (i.e., q) to thenew vma, both munmap operations would trigger vma_close, causingq->qfr to be freed twice(qfr will be set to null here, so repeatedrelease is ok).

If the queue count is increased, the NIC can write pastthe end of the allocated stats region, causing memory corruption.If the queue count is decreased, there is a gap between the driverand NIC stats, leading to incorrect stats reporting.This change fixes the issue by allocating stats region with maximumsize, and the offset calculation for NIC stats is changed to matchwith the calculation of the NIC.

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

And a potential crashat this point may not realizs that these extents could have been targetof in-flight IO and would need to be resynced just in case.Also, once the request completes, it will give up activity log references itdoes not even hold, which will trigger a BUG_ON(refcnt == 0) in lc_put().Fix:Do not crash the kernel for a condition that is harmless during normaloperation: also catch "e->refcnt == 0", not only "e == NULL"when being noisy about "al_complete_io() called on inactive extent %u\n".And do not try to be smart and "guess" whether something will work, thenbe surprised when it does not.Deal with the fact that it may or may not work. If it does not, remember apossible "partially in activity log" state (only possible for requests thatcross extent boundaries), and return an error code fromdrbd_al_begin_io_nonblock().A latter call for the same request will then resume from where we left off.

An attacker can craft a malicious filename by including terminal escape sequences to hide the addition or removal of the file from the report and/or tamper with the log output. A local user might exploit this to bypass the AIDE detection of malicious files. Additionally the output of extended attribute key names and symbolic links targets are also not properly neutralized. This issue has been patched in version 0.19.2.

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.

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: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.

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().

When thetimeout is hit on the server, the server will send a FIN, which triggersa cancellation request via xs_reset_transport().

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: cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the public_key_from_numbers (or EllipticCurvePublicNumbers.public_key()), EllipticCurvePublicNumbers.public_key(), load_der_public_key() and load_pem_public_key() functions do not verify that the point belongs to the expected prime-order subgroup of the curve. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification (ECDSA) and shared key negotiation (ECDH). When the victim computes the shared secret as S = [victim_private_key]P via ECDH, this leaks information about victim_private_key mod (small_subgroup_order). For curves with cofactor > 1, this reveals the least significant bits of the private key. When these weak public keys are used in ECDSA , it's easy to forge signatures on the small subgroup. Only SECT curves are impacted by this. This vulnerability is fixed in 46.0.5.

Description: Issue summary: During processing of a crafted CMS EnvelopedData messagewith KeyTransportRecipientInfo a NULL pointer dereference can happen.Impact summary: Applications that process attacker-controlled CMS data maycrash before authentication or cryptographic operations occur resulting inDenial of Service.When a CMS EnvelopedData message that uses KeyTransportRecipientInfo withRSA-OAEP encryption is processed, the optional parameters field ofRSA-OAEP SourceFunc algorithm identifier is examined without checkingfor its presence. This results in a NULL pointer dereference if the fieldis missing.Applications and services that call CMS_decrypt() on untrusted input(e.g., S/MIME processing or CMS-based protocols) are vulnerable.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary.

Description: Calling NSS-backed functions that support caching via nscd may call the nscd client side code and in the GNU C Library version 2.36 under high load on x86_64 systems, the client may call memcmp on inputs that are concurrently modified by other processes or threads and crash.The nscd client in the GNU C Library uses the memcmp function with inputs that may be concurrently modified by another thread, potentially resulting in spurious cache misses, which in itself is not a security issue. However in the GNU C Library version 2.36 an optimized implementation of memcmp was introduced for x86_64 which could crash when invoked with such undefined behaviour, turning this into a potential crash of the nscd client and the application that uses it. This implementation was backported to the 2.35 branch, making the nscd client in that branch vulnerable as well. Subsequently, the fix for this issue was backported to all vulnerable branches in the GNU C Library repository.It is advised that distributions that may have cherry-picked the memcpy SSE2 optimization in their copy of the GNU C Library, also apply the fix to avoid the potential crash in the nscd client.

Description: Rack is a modular Ruby web server interface. Prior to versions 2.2.20, 3.1.18, and 3.2.3, a possible information disclosure vulnerability existed in `Rack::Sendfile` when running behind a proxy that supports `x-sendfile` headers (such as Nginx). Specially crafted headers could cause `Rack::Sendfile` to miscommunicate with the proxy and trigger unintended internal requests, potentially bypassing proxy-level access restrictions. When `Rack::Sendfile` received untrusted `x-sendfile-type` or `x-accel-mapping` headers from a client, it would interpret them as proxy configuration directives. This could cause the middleware to send a "redirect" response to the proxy, prompting it to reissue a new internal request that was not subject to the proxy's access controls. An attacker could exploit this by setting a crafted `x-sendfile-type: x-accel-redirect` header, setting a crafted `x-accel-mapping` header, and requesting a path that qualifies for proxy-based acceleration. Attackers could bypass proxy-enforced restrictions and access internal endpoints intended to be protected (such as administrative pages). The vulnerability did not allow arbitrary file reads but could expose sensitive application routes. This issue only affected systems meeting all of the following conditions: The application used `Rack::Sendfile` with a proxy that supports `x-accel-redirect` (e.g., Nginx); the proxy did **not** always set or remove the `x-sendfile-type` and `x-accel-mapping` headers; and the application exposed an endpoint that returned a body responding to `.to_path`. Users should upgrade to Rack versions 2.2.20, 3.1.18, or 3.2.3, which require explicit configuration to enable `x-accel-redirect`. Alternatively, configure the proxy to always set or strip the header, or in Rails applications, disable sendfile completely.

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.

Similar to the connection usage countlogic, the waiter signaled by complete() (e.g., in the session releasepath) may wake up and free the iscsit_session structure immediately.This creates a race condition where the current thread may attempt toexecute spin_unlock_bh() on a session structure that has already beendeallocated, resulting in a KASAN slab-use-after-free.To resolve this, release the session_usage_lock before calling complete()to ensure all dereferences of the sess pointer are finished before thewaiter is allowed to proceed with deallocation.

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

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: support non-r10 register spill/fill to/from stack in precision trackingUse instruction (jump) history to record instructions that performedregister spill/fill to/from stack, regardless if this was done throughread-only r10 register, or any other register after copying r10 into it*and* potentially adjusting offset.To make this work reliably, we push extra per-instruction flags intoinstruction history, encoding stack slot index (spi) and stack framenumber in extra 10 bit flags we take away from prev_idx in instructionhistory. We don't touch idx field for maximum performance, as it'schecked most frequently during backtracking.This change removes basically the last remaining practical limitation ofprecision backtracking logic in BPF verifier. It fixes knowndeficiencies, but also opens up new opportunities to reduce number ofverified states, explored in the subsequent patches.There are only three differences in selftests' BPF object filesaccording to veristat, all in the positive direction (less states).File Program Insns (A) Insns (B) Insns (DIFF) States (A) States (B) States (DIFF)-------------------------------------- ------------- --------- --------- ------------- ---------- ---------- -------------test_cls_redirect_dynptr.bpf.linked3.o cls_redirect 2987 2864 -123 (-4.12%) 240 231 -9 (-3.75%)xdp_synproxy_kern.bpf.linked3.o syncookie_tc 82848 82661 -187 (-0.23%) 5107 5073 -34 (-0.67%)xdp_synproxy_kern.bpf.linked3.o syncookie_xdp 85116 84964 -152 (-0.18%) 5162 5130 -32 (-0.62%)Note, I avoided renaming jmp_history to more generic insn_hist tominimize number of lines changed and potential merge conflicts betweenbpf and bpf-next trees.Notice also cur_hist_entry pointer reset to NULL at the beginning ofinstruction verification loop. This pointer avoids the problem ofrelying on last jump history entry's insn_idx to determine whether wealready have entry for current instruction or not. It can happen that weadded jump history entry because current instruction is_jmp_point(), butalso we need to add instruction flags for stack access. In this case, wedon't want to entries, so we need to reuse last added entry, if it ispresent.Relying on insn_idx comparison has the same ambiguity problem as the onethat was fixed recently in [0], so we avoid that.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: ses: Handle enclosure with just a primary component gracefullyThis reverts commit 3fe97ff3d949 ("scsi: ses: Don't attach if enclosurehas no components") and introduces proper handling of case where there areno detected secondary components, but primary component (enumerated innum_enclosures) does exist.

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

Description: In the Linux kernel, the following vulnerability has been resolved:netfilter: bridge: replace physindev with physinif in nf_bridge_infoAn skb can be added to a neigh->arp_queue while waiting for an arpreply. Where original skb's skb->dev can be different to neigh'sneigh->dev. For instance in case of bridging dnated skb from one veth toanother, the skb would be added to a neigh->arp_queue of the bridge.As skb->dev can be reset back to nf_bridge->physindev and used, and asthere is no explicit mechanism that prevents this physindev from beenfreed under us (for instance neigh_flush_dev doesn't cleanup skbs fromdifferent device's neigh queue) we can crash on e.g. this stack:arp_process neigh_update skb = __skb_dequeue(&neigh->arp_queue) neigh_resolve_output(..., skb) ... br_nf_dev_xmit br_nf_pre_routing_finish_bridge_slow skb->dev = nf_bridge->physindev br_handle_frame_finishLet's use plain ifindex instead of net_device link. To peek into theoriginal net_device we will use dev_get_by_index_rcu(). Thus either weget device and are safe to use it or we don't get it and drop skb.

Description: In the Linux kernel, the following vulnerability has been resolved:btrfs: fix qgroup reserve leaks in cow_file_rangeIn the buffered write path, the dirty page owns the qgroup reserve untilit creates an ordered_extent.Therefore, any errors that occur before the ordered_extent is createdmust free that reservation, or else the space is leaked. The fstestgeneric/475 exercises various IO error paths, and is able to triggererrors in cow_file_range where we fail to get to allocating the orderedextent. Note that because we *do* clear delalloc, we are likely toremove the inode from the delalloc list, so the inodes/pages to not haveinvalidate/launder called on them in the commit abort path.This results in failures at the unmount stage of the test that look like: BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure BTRFS warning (device dm-8 state EA): qgroup 0/5 has unreleased space, type 0 rsv 28672 ------------[ cut here ]------------ WARNING: CPU: 3 PID: 22588 at fs/btrfs/disk-io.c:4333 close_ctree+0x222/0x4d0 [btrfs] Modules linked in: btrfs blake2b_generic libcrc32c xor zstd_compress raid6_pq CPU: 3 PID: 22588 Comm: umount Kdump: loaded Tainted: G W 6.10.0-rc7-gab56fde445b8 #21 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014 RIP: 0010:close_ctree+0x222/0x4d0 [btrfs] RSP: 0018:ffffb4465283be00 EFLAGS: 00010202 RAX: 0000000000000001 RBX: ffffa1a1818e1000 RCX: 0000000000000001 RDX: 0000000000000000 RSI: ffffb4465283bbe0 RDI: ffffa1a19374fcb8 RBP: ffffa1a1818e13c0 R08: 0000000100028b16 R09: 0000000000000000 R10: 0000000000000003 R11: 0000000000000003 R12: ffffa1a18ad7972c R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 FS: 00007f9168312b80(0000) GS:ffffa1a4afcc0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f91683c9140 CR3: 000000010acaa000 CR4: 00000000000006f0 Call Trace: ? close_ctree+0x222/0x4d0 [btrfs] ? __warn.cold+0x8e/0xea ? close_ctree+0x222/0x4d0 [btrfs] ? report_bug+0xff/0x140 ? handle_bug+0x3b/0x70 ? exc_invalid_op+0x17/0x70 ? asm_exc_invalid_op+0x1a/0x20 ? close_ctree+0x222/0x4d0 [btrfs] generic_shutdown_super+0x70/0x160 kill_anon_super+0x11/0x40 btrfs_kill_super+0x11/0x20 [btrfs] deactivate_locked_super+0x2e/0xa0 cleanup_mnt+0xb5/0x150 task_work_run+0x57/0x80 syscall_exit_to_user_mode+0x121/0x130 do_syscall_64+0xab/0x1a0 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7f916847a887 ---[ end trace 0000000000000000 ]--- BTRFS error (device dm-8 state EA): qgroup reserved space leakedCases 2 and 3 in the out_reserve path both pertain to this type of leakand must free the reserved qgroup data.

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

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

This was reported as an issue on android devices usingkernel 6.6 due to the resume hook which had been added for usb joycons.First, set a new state value to JOYCON_CTLR_STATE_SUSPENDED in anewly-added nintendo_hid_suspend. This makes sure we will not stall outthe kernel waiting for input reports during led classdev suspend. Thestalls could happen if connectivity is unreliable or lost to thecontroller prior to suspend.Second, since we lose connectivity during suspend, do not tryjoycon_init() for bluetooth controllers in the nintendo_hid_resume path.Tested via multiple suspend/resume flows when using the controller bothin USB and bluetooth modes.

Description: In the Linux kernel, the following vulnerability has been resolved:pinctrl: qcom: msm: mark certain pins as invalid for interruptsOn some platforms, the UFS-reset pin has no interrupt logic in TLMM butis nevertheless registered as a GPIO in the kernel. This enables theuser-space to trigger a BUG() in the pinctrl-msm driver by running, forexample: `gpiomon -c 0 113` on RB2.The exact culprit is requesting pins whose intr_detection_width settingis not 1 or 2 for interrupts. This hits a BUG() inmsm_gpio_irq_set_type(). Potentially crashing the kernel due to aninvalid request from user-space is not optimal, so let's go through thepins and mark those that would fail the check as invalid for the irq chipas we should not even register them as available irqs.This function can be extended if we determine that there are morecorner-cases like this.

Description: In the Linux kernel, the following vulnerability has been resolved:drm/imagination: Fix kernel crash when hard resetting the GPUThe GPU hard reset sequence calls pm_runtime_force_suspend() andpm_runtime_force_resume(), which according to their documentation shouldonly be used during system-wide PM transitions to sleep states.The main issue though is that depending on some internal runtime PMstate as seen by pm_runtime_force_suspend() (whether the usage count is<= 1), pm_runtime_force_resume() might not resume the device unlessneeded. If that happens, the runtime PM resume callbackpvr_power_device_resume() is not called, the GPU clocks are notre-enabled, and the kernel crashes on the next attempt to access GPUregisters as part of the power-on sequence.Replace calls to pm_runtime_force_suspend() andpm_runtime_force_resume() with direct calls to the driver's runtime PMcallbacks, pvr_power_device_suspend() and pvr_power_device_resume(),to ensure clocks are re-enabled and avoid the kernel crash.

However, if the regulatoris marked as always-on, regulator_is_enabled() continues to return true,leading to an incorrect attempt to disable a regulator which is notenabled.This can result in warnings such as:[ 250.155624] WARNING: CPU: 1 PID: 7326 at drivers/regulator/core.c:3004_regulator_disable+0xe4/0x1a0[ 250.155652] unbalanced disables for VIN_SYS_5V0To fix this, we move the regulator control logic intotegra186_xusb_padctl_id_override() function since it's directly relatedto the ID override state. The regulator is now only disabled when the roletransitions from USB_ROLE_HOST to USB_ROLE_NONE, by checking the VBUS_IDregister. This ensures that regulator enable/disable operations areproperly balanced and only occur when actually transitioning to/from hostmode.

However, the state mighthave been freed by the time of this lookup.Currently, if the state is not found, only a counter is incremented.The secpath (sp) extension on the skb is not removed, resulting insp->len becoming 0.Subsequently, functions like __xfrm_policy_check() attempt to accessfields such as xfrm_input_state(skb)->xso.type (which dereferencessp->xvec[sp->len - 1]) without first validating sp->len. This leads toa crash when dereferencing an invalid state pointer.This patch prevents the crash by explicitly removing the secpathextension from the skb if the xfrm state is not found after hardwaredecryption. This ensures downstream functions do not operate on azero-length secpath.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:LoongArch: KVM: Fix stack protector issue in send_ipi_data()Function kvm_io_bus_read() is called in function send_ipi_data(), buffersize of parameter *val should be at least 8 bytes. Since some emulationfunctions like loongarch_ipi_readl() and kvm_eiointc_read() will writethe buffer *val with 8 bytes signed extension regardless parameter len.Otherwise there will be buffer overflow issue when CONFIG_STACKPROTECTORis enabled.

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.

At this point, due to the prior trace_iterator_reset, both`iter.seq.len` and `iter.seq.size` were set to 0. Since they are equal,the WARN_ON_ONCE condition is triggered.Move the trace_printk_seq() into the if block that checks to make sure thereturn value of trace_find_next_entry_inc() is non-NULL inftrace_dump_one(), ensuring the 'iter.seq' is properly populated beforesubsequent operations.

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.

Send data less than cork_bytesAt 5., the data is carried over to the next sendmsg() as it issmaller than the cork_bytes specified by bpf_msg_cork_bytes().Then, tcp_bpf_send_verdict() tries to allocate psock->cork to holdthe data, but this fails silently due to fault injection + __GFP_NOWARN.If the allocation fails, we need to revert the sk->sk_forward_allocchange done by sk_msg_alloc().Let's call sk_msg_free() when tcp_bpf_send_verdict fails to allocatepsock->cork.The "*copied" also needs to be updated such that a proper error canbe returned to the caller, sendmsg. It fails to allocate psock->cork.Nothing has been corked so far, so this patch simply sets "*copied"to 0.[0]:WARNING: net/ipv4/af_inet.c:156 at inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156, CPU#1: syz-executor/5983Modules linked in:CPU: 1 UID: 0 PID: 5983 Comm: syz-executor Not tainted syzkaller #0 PREEMPT(full)Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/12/2025RIP: 0010:inet_sock_destruct+0x623/0x730 net/ipv4/af_inet.c:156Code: 0f 0b 90 e9 62 fe ff ff e8 7a db b5 f7 90 0f 0b 90 e9 95 fe ff ff e8 6c db b5 f7 90 0f 0b 90 e9 bb fe ff ff e8 5e db b5 f7 90 <0f> 0b 90 e9 e1 fe ff ff 89 f9 80 e1 07 80 c1 03 38 c1 0f 8c 9f fcRSP: 0018:ffffc90000a08b48 EFLAGS: 00010246RAX: ffffffff8a09d0b2 RBX: dffffc0000000000 RCX: ffff888024a23c80RDX: 0000000000000100 RSI: 0000000000000fff RDI: 0000000000000000RBP: 0000000000000fff R08: ffff88807e07c627 R09: 1ffff1100fc0f8c4R10: dffffc0000000000 R11: ffffed100fc0f8c5 R12: ffff88807e07c380R13: dffffc0000000000 R14: ffff88807e07c60c R15: 1ffff1100fc0f872FS: 00005555604c4500(0000) GS:ffff888125af1000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00005555604df5c8 CR3: 0000000032b06000 CR4: 00000000003526f0Call Trace: __sk_destruct+0x86/0x660 net/core/sock.c:2339 rcu_do_batch kernel/rcu/tree.c:2605 [inline] rcu_core+0xca8/0x1770 kernel/rcu/tree.c:2861 handle_softirqs+0x286/0x870 kernel/softirq.c:579 __do_softirq kernel/softirq.c:613 [inline] invoke_softirq kernel/softirq.c:453 [inline] __irq_exit_rcu+0xca/0x1f0 kernel/softirq.c:680 irq_exit_rcu+0x9/0x30 kernel/softirq.c:696 instr_sysvec_apic_timer_interrupt arch/x86/kernel/apic/apic.c:1052 [inline] sysvec_apic_timer_interrupt+0xa6/0xc0 arch/x86/kernel/apic/apic.c:1052

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: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:mm: prevent poison consumption when splitting THPWhen performing memory error injection on a THP (Transparent Huge Page)mapped to userspace on an x86 server, the kernel panics with the followingtrace. The expected behavior is to terminate the affected process insteadof panicking the kernel, as the x86 Machine Check code can recover from anin-userspace #MC. mce: [Hardware Error]: CPU 0: Machine Check Exception: f Bank 3: bd80000000070134 mce: [Hardware Error]: RIP 10: {memchr_inv+0x4c/0xf0} mce: [Hardware Error]: TSC afff7bbff88a ADDR 1d301b000 MISC 80 PPIN 1e741e77539027db mce: [Hardware Error]: PROCESSOR 0:d06d0 TIME 1758093249 SOCKET 0 APIC 0 microcode 80000320 mce: [Hardware Error]: Run the above through 'mcelog --ascii' mce: [Hardware Error]: Machine check: Data load in unrecoverable area of kernel Kernel panic - not syncing: Fatal local machine checkThe root cause of this panic is that handling a memory failure triggeredby an in-userspace #MC necessitates splitting the THP. The splittingprocess employs a mechanism, implemented intry_to_map_unused_to_zeropage(), which reads the pages in the THP toidentify zero-filled pages. However, reading the pages in the THP resultsin a second in-kernel #MC, occurring before the initial memory_failure()completes, ultimately leading to a kernel panic. See the kernel paniccall trace on the two #MCs. First Machine Check occurs // [1] memory_failure() // [2] try_to_split_thp_page() split_huge_page() split_huge_page_to_list_to_order() __folio_split() // [3] remap_page() remove_migration_ptes() remove_migration_pte() try_to_map_unused_to_zeropage() // [4] memchr_inv() // [5] Second Machine Check occurs // [6] Kernel panic[1] Triggered by accessing a hardware-poisoned THP in userspace, which is typically recoverable by terminating the affected process.[2] Call folio_set_has_hwpoisoned() before try_to_split_thp_page().[3] Pass the RMP_USE_SHARED_ZEROPAGE remap flag to remap_page().[4] Try to map the unused THP to zeropage.[5] Re-access pages in the hw-poisoned THP in the kernel.[6] Triggered in-kernel, leading to a panic kernel.In Step[2], memory_failure() sets the poisoned flag on the page in the THPby TestSetPageHWPoison() before calling try_to_split_thp_page().As suggested by David Hildenbrand, fix this panic by not accessing to thepoisoned page in the THP during zeropage identification, while continuingto scan unaffected pages in the THP for possible zeropage mapping. Thisprevents a second in-kernel #MC that would cause kernel panic in Step[4].Thanks to Andrew Zaborowski for his initial work on fixing this issue.

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: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:codetag: debug: handle existing CODETAG_EMPTY in mark_objexts_empty for slabobj_extWhen alloc_slab_obj_exts() fails and then later succeeds in allocating aslab extension vector, it calls handle_failed_objexts_alloc() to mark allobjects in the vector as empty. As a result all objects in this slab(slabA) will have their extensions set to CODETAG_EMPTY.Later on if this slabA is used to allocate a slabobj_ext vector foranother slab (slabB), we end up with the slabB->obj_exts pointing to aslabobj_ext vector that itself has a non-NULL slabobj_ext equal toCODETAG_EMPTY. When slabB gets freed, free_slab_obj_exts() is called tofree slabB->obj_exts vector. free_slab_obj_exts() calls mark_objexts_empty(slabB->obj_exts) which willgenerate a warning because it expects slabobj_ext vectors to have a NULLobj_ext, not CODETAG_EMPTY.Modify mark_objexts_empty() to skip the warning and setting the obj_extvalue if it's already set to CODETAG_EMPTY.To quickly detect this WARN, I modified the code fromWARN_ON(slab_exts[offs].ref.ct) to BUG_ON(slab_exts[offs].ref.ct == 1);We then obtained this message:[21630.898561] ------------[ cut here ]------------[21630.898596] kernel BUG at mm/slub.c:2050![21630.898611] Internal error: Oops - BUG: 00000000f2000800 [#1] SMP[21630.900372] Modules linked in: squashfs isofs vfio_iommu_type1 vhost_vsock vfio vhost_net vmw_vsock_virtio_transport_common vhost tap vhost_iotlb iommufd vsock binfmt_misc nfsv3 nfs_acl nfs lockd grace netfs tls rds dns_resolver tun brd overlay ntfs3 exfat btrfs blake2b_generic xor xor_neon raid6_pq loop sctp ip6_udp_tunnel udp_tunnel nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables rfkill ip_set sunrpc vfat fat joydev sg sch_fq_codel nfnetlink virtio_gpu sr_mod cdrom drm_client_lib virtio_dma_buf drm_shmem_helper drm_kms_helper drm ghash_ce backlight virtio_net virtio_blk virtio_scsi net_failover virtio_console failover virtio_mmio dm_mirror dm_region_hash dm_log dm_multipath dm_mod fuse i2c_dev virtio_pci virtio_pci_legacy_dev virtio_pci_modern_dev virtio virtio_ring autofs4 aes_neon_bs aes_ce_blk [last unloaded: hwpoison_inject][21630.909177] CPU: 3 UID: 0 PID: 3787 Comm: kylin-process-m Kdump: loaded Tainted: G W 6.18.0-rc1+ #74 PREEMPT(voluntary)[21630.910495] Tainted: [W]=WARN[21630.910867] Hardware name: QEMU KVM Virtual Machine, BIOS unknown 2/2/2022[21630.911625] pstate: 80400005 (Nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)[21630.912392] pc : __free_slab+0x228/0x250[21630.912868] lr : __free_slab+0x18c/0x250[21630.913334] sp : ffff8000a02f73e0[21630.913830] x29: ffff8000a02f73e0 x28: fffffdffc43fc800 x27: ffff0000c0011c40[21630.914677] x26: ffff0000c000cac0 x25: ffff00010fe5e5f0 x24: ffff000102199b40[21630.915469] x23: 0000000000000003 x22: 0000000000000003 x21: ffff0000c0011c40[21630.916259] x20: fffffdffc4086600 x19: fffffdffc43fc800 x18: 0000000000000000[21630.917048] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000[21630.917837] x14: 0000000000000000 x13: 0000000000000000 x12: ffff70001405ee66[21630.918640] x11: 1ffff0001405ee65 x10: ffff70001405ee65 x9 : ffff800080a295dc[21630.919442] x8 : ffff8000a02f7330 x7 : 0000000000000000 x6 : 0000000000003000[21630.920232] x5 : 0000000024924925 x4 : 0000000000000001 x3 : 0000000000000007[21630.921021] x2 : 0000000000001b40 x1 : 000000000000001f x0 : 0000000000000001[21630.921810] Call trace:[21630.922130] __free_slab+0x228/0x250 (P)[21630.922669] free_slab+0x38/0x118[21630.923079] free_to_partial_list+0x1d4/0x340[21630.923591] __slab_free+0x24c/0x348[21630.924024] ___cache_free+0xf0/0x110[21630.924468] qlist_free_all+0x78/0x130[21630.924922] kasan_quarantine_reduce+0x11---truncated---

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: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

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.

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

Description: In the Linux kernel, the following vulnerability has been resolved:mm/memfd: fix information leak in hugetlb foliosWhen allocating hugetlb folios for memfd, three initialization steps aremissing:1. Folios are not zeroed, leading to kernel memory disclosure to userspace2. Folios are not marked uptodate before adding to page cache3. hugetlb_fault_mutex is not taken before hugetlb_add_to_page_cache()The memfd allocation path bypasses the normal page fault handler(hugetlb_no_page) which would handle all of these initialization steps. This is problematic especially for udmabuf use cases where folios arepinned and directly accessed by userspace via DMA.Fix by matching the initialization pattern used in hugetlb_no_page():- Zero the folio using folio_zero_user() which is optimized for huge pages- Mark it uptodate with folio_mark_uptodate()- Take hugetlb_fault_mutex before adding to page cache to prevent racesThe folio_zero_user() change also fixes a potential security issue whereuninitialized kernel memory could be disclosed to userspace through read()or mmap() operations on the memfd.

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:netconsole: Acquire su_mutex before navigating configs hierarchyThere is a race between operations that iterate over the userdatacg_children list and concurrent add/remove of userdata items throughconfigfs. The update_userdata() function iterates over thent->userdata_group.cg_children list, and count_extradata_entries() alsoiterates over this same list to count nodes.Quoting from Documentation/filesystems/configfs.rst:> A subsystem can navigate the cg_children list and the ci_parent pointer> to see the tree created by the subsystem. This can race with configfs'> management of the hierarchy, so configfs uses the subsystem mutex to> protect modifications. Whenever a subsystem wants to navigate the> hierarchy, it must do so under the protection of the subsystem> mutex.Without proper locking, if a userdata item is added or removedconcurrently while these functions are iterating, the list can beaccessed in an inconsistent state. For example, the list_for_each() loopcan reach a node that is being removed from the list by list_del_init()which sets the nodes' .next pointer to point to itself, so the loop willnever end (or reach the WARN_ON_ONCE in update_userdata() ).Fix this by holding the configfs subsystem mutex (su_mutex) during alloperations that iterate over cg_children.This includes:- userdatum_value_store() which calls update_userdata() to iterate over cg_children- All sysdata_*_enabled_store() functions which call count_extradata_entries() to iterate over cg_childrenThe su_mutex must be acquired before dynamic_netconsole_mutex to avoidpotential lock ordering issues, as configfs operations may already holdsu_mutex when calling into our code.

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.

For NAPI this is correctly handled as thenapi_schedule_prep() check will prevent multiple instances from gettingscheduled, but for the remaining code in veth_pool() this can runconcurrent with the newly started NAPI instance.The problem/race is that xdp_clear_return_frame_no_direct() isn'tdesigned to be nested.Prior to commit 401cb7dae813 ("net: Reference bpf_redirect_info viatask_struct on PREEMPT_RT.") the temporary BPF net contextbpf_redirect_info was stored per CPU, where this wasn't an issue. Sincethis commit the BPF context is stored in 'current' task_struct. Whenrunning veth in threaded-NAPI mode, then the kthread becomes the storagearea. Now a race exists between two concurrent veth_pool() function callsone exiting NAPI and one running new NAPI, both using the same BPF netcontext.Race is when another CPU gets within the xdp_set_return_frame_no_direct()section before exiting veth_pool() calls the clear-functionxdp_clear_return_frame_no_direct().

Description: In the Linux kernel, the following vulnerability has been resolved:gfs2: Prevent recursive memory reclaimFunction new_inode() returns a new inode with inode->i_mapping->gfp_maskset to GFP_HIGHUSER_MOVABLE. This value includes the __GFP_FS flag, soallocations in that address space can recurse into filesystem memoryreclaim. We don't want that to happen because it can consume asignificant amount of stack memory.Worse than that is that it can also deadlock: for example, in severalplaces, gfs2_unstuff_dinode() is called inside filesystem transactions.This calls filemap_grab_folio(), which can allocate a new folio, whichcan trigger memory reclaim. If memory reclaim recurses into thefilesystem and starts another transaction, a deadlock will ensue.To fix these kinds of problems, prevent memory reclaim from recursinginto filesystem code by making sure that the gfp_mask of inode addressspaces doesn't include __GFP_FS.The "meta" and resource group address spaces were already using GFP_NOFSas their gfp_mask (which doesn't include __GFP_FS). The default valueof GFP_HIGHUSER_MOVABLE is less restrictive than GFP_NOFS, though. Toavoid being overly limiting, use the default value and only knock offthe __GFP_FS flag. I'm not sure if this will actually make adifference, but it also shouldn't hurt.This patch is loosely based on commit ad22c7a043c2 ("xfs: prevent stackoverflows from page cache allocation").Fixes xfstest generic/273.

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:btrfs: fix double free of qgroup record after failure to add delayed ref headIn the previous code it was possible to incur into a double kfree()scenario when calling add_delayed_ref_head(). This could happen if therecord was reported to already exist in thebtrfs_qgroup_trace_extent_nolock() call, but then there was an errorlater on add_delayed_ref_head(). In this case, sinceadd_delayed_ref_head() returned an error, the caller went to free therecord. Since add_delayed_ref_head() couldn't set this kfree'd pointerto NULL, then kfree() would have acted on a non-NULL 'record' objectwhich was pointing to memory already freed by the callee.The problem comes from the fact that the responsibility to kfree theobject is on both the caller and the callee at the same time. Hence, thefix for this is to shift the ownership of the 'qrecord' object out ofthe add_delayed_ref_head(). That is, we will never attempt to kfree()the given object inside of this function, and will expect the caller toact on the 'qrecord' object on its own. The only exception where the'qrecord' object cannot be kfree'd is if it was inserted into thetracing logic, for which we already have the 'qrecord_inserted_ret'boolean to account for this. Hence, the caller has to kfree the objectonly if add_delayed_ref_head() reports not to have inserted it on thetracing logic.As a side-effect of the above, we must guarantee that'qrecord_inserted_ret' is properly initialized at the start of thefunction, not at the end, and then set when an actual inserthappens. This way we avoid 'qrecord_inserted_ret' having an invalidvalue on an early exit.The documentation from the add_delayed_ref_head() has also been updatedto reflect on the exact ownership of the 'qrecord' object.

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:ALSA: usb-mixer: us16x08: validate meter packet indicesget_meter_levels_from_urb() parses the 64-byte meter packets sent bythe device and fills the per-channel arrays meter_level[],comp_level[] and master_level[] in struct snd_us16x08_meter_store.Currently the function derives the channel index directly from themeter packet (MUB2(meter_urb, s) - 1) and uses it to index thosearrays without validating the range. If the packet contains anegative or out-of-range channel number, the driver may write pastthe end of these arrays.Introduce a local channel variable and validate it before updating thearrays. We reject negative indices, limit meter_level[] andcomp_level[] to SND_US16X08_MAX_CHANNELS, and guard master_level[]updates with ARRAY_SIZE(master_level).

Description: In the Linux kernel, the following vulnerability has been resolved:media: vidtv: initialize local pointers upon transfer of memory ownershipvidtv_channel_si_init() creates a temporary list (program, service, event)and ownership of the memory itself is transferred to the PAT/SDT/EITtables through vidtv_psi_pat_program_assign(),vidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().The problem here is that the local pointer where the memory ownershiptransfer was completed is not initialized to NULL. This causes thevidtv_psi_pmt_create_sec_for_each_pat_entry() function to fail, andin the flow that jumps to free_eit, the memory that was freed byvidtv_psi_*_table_destroy() can be accessed again byvidtv_psi_*_event_destroy() due to the uninitialized local pointer, so itis freed once again.Therefore, to prevent use-after-free and double-free vulnerability,local pointers must be initialized to NULL when transferring memoryownership.

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

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.

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: An issue was discovered in Binutils before 2.46. The objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed debug information. A logic flaw in the handling of DWARF location list headers can cause objdump to enter an unbounded loop and produce endless output until manually interrupted. This issue affects versions prior to the upstream fix and allows a local attacker to cause excessive resource consumption by supplying a malicious input file.

Description: Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug_rnglists data. A logic error in the handling of the debug_rnglists header can cause objdump to repeatedly print the same warning message and fail to terminate, resulting in an unbounded logging loop until the process is interrupted. The issue was observed in binutils 2.44. A local attacker can exploit this vulnerability by supplying a malicious input file, leading to excessive CPU and I/O usage and preventing completion of the objdump analysis.

Description: In the Linux kernel, the following vulnerability has been resolved:net: hns3: using the num_tqps in the vf driver to apply for resourcesCurrently, hdev->htqp is allocated using hdev->num_tqps, and kinfo->tqpis allocated using kinfo->num_tqps. 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:powerpc/64s/slb: Fix SLB multihit issue during SLB preloadOn systems using the hash MMU, there is a software SLB preload cache thatmirrors the entries loaded into the hardware SLB buffer. This preloadcache is subject to periodic eviction - typically after every 256 contextswitches - to remove old entry.To optimize performance, the kernel skips switch_mmu_context() inswitch_mm_irqs_off() when the prev and next mm_struct are the same.However, on hash MMU systems, this can lead to inconsistencies betweenthe hardware SLB and the software preload cache.If an SLB entry for a process is evicted from the software cache on oneCPU, and the same process later runs on another CPU without executingswitch_mmu_context(), the hardware SLB may retain stale entries. If thekernel then attempts to reload that entry, it can trigger an SLBmulti-hit error.The following timeline shows how stale SLB entries are created and cancause a multi-hit error when a process moves between CPUs without aMMU context switch.CPU 0 CPU 1----- -----Process Pexec swapper/1 load_elf_binary begin_new_exc activate_mm switch_mm_irqs_off switch_mmu_context switch_slb /* * This invalidates all * the entries in the HW * and setup the new HW * SLB entries as per the * preload cache. */context_switchsched_migrate_task migrates process P to cpu-1Process swapper/0 context switch (to process P)(uses mm_struct of Process P) switch_mm_irqs_off() switch_slb load_slb++ /* * load_slb becomes 0 here * and we evict an entry from * the preload cache with * preload_age().

When usedin lockless contexts involving shared driver data, this leads toTime-of-Check to Time-of-Use (TOCTOU) race conditions, potentiallycausing divide-by-zero errors.Convert the macro to a static function. This guarantees that argumentsare evaluated only once (pass-by-value), preventing the raceconditions.Additionally, in store_fan_div, move the calculation of the minimumlimit inside the update lock. This ensures that the read-modify-writesequence operates on consistent data.Adhere to the principle of minimal changes by only converting macrosthat evaluate arguments multiple times and are used in locklesscontexts.

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:drm/i915/gem: Zero-initialize the eb.vma array in i915_gem_do_execbufferInitialize the eb.vma array with values of 0 when the eb structure isfirst set up. In particular, this sets the eb->vma[i].vma pointers toNULL, simplifying cleanup and getting rid of the bug described below.During the execution of eb_lookup_vmas(), the eb->vma array issuccessively filled up with struct eb_vma objects. This process includescalling eb_add_vma(), which might fail; however, even in the event offailure, eb->vma[i].vma is set for the currently processed buffer.If eb_add_vma() fails, eb_lookup_vmas() returns with an error, whichprompts a call to eb_release_vmas() to clean up the mess. Sinceeb_lookup_vmas() might fail during processing any (possibly not first)buffer, eb_release_vmas() checks whether a buffer's vma is NULL to knowat what point did the lookup function fail.In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helperfunction eb_lookup_vma() or eb_validate_vma() fails. eb->vma[i+1].vma isset to NULL in case i915_gem_object_userptr_submit_init() fails; thecurrent one needs to be cleaned up by eb_release_vmas() at this point,so the next one is set. If eb_add_vma() fails, neither the current northe next vma is set to NULL, which is a source of a NULL deref bugdescribed in the issue linked in the Closes tag.When entering eb_lookup_vmas(), the vma pointers are set to the slabpoison value, instead of NULL. This doesn't matter for the actuallookup, since it gets overwritten anyway, however the eb_release_vmas()function only recognizes NULL as the stopping value, hence the pointersare being set to NULL as they go in case of intermediate failure. Thispatch changes the approach to filling them all with NULL at the startinstead, rather than handling that manually during failure.(cherry picked from commit 08889b706d4f0b8d2352b7ca29c2d8df4d0787cd)

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

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. When that happens the mount fails and we get a stack trace like the following: [87.2314] BTRFS info (device dm-0): start tree-log replay [87.2318] BTRFS critical (device dm-0): failed to delete reference to subvol, root 5 inode 256 parent 259 [87.2332] ------------[ cut here ]------------ [87.2338] BTRFS: Transaction aborted (error -2) [87.2346] WARNING: CPU: 1 PID: 638968 at fs/btrfs/inode.c:4345 __btrfs_unlink_inode+0x416/0x440 [btrfs] [87.2368] Modules linked in: btrfs loop dm_thin_pool (...)

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: 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.

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.

A retry to changeprofile, e.g. another attempt to call mlx5e_netdev_change_profile viaswitchdev mode change, will crash trying to access the now NULLpriv->mdev.This fix allows mlx5e_netdev_change_profile() to handle previousfailures and an empty priv, by not assuming priv is valid.Pass netdev and mdev to all flows requiringmlx5e_netdev_change_profile() and avoid passing priv.In mlx5e_netdev_change_profile() check if current priv is valid, and ifnot, just attach the new profile without trying to access the old one.This fixes the following oops, when enabling switchdev mode for the 2ndtime after first time failure: ## Enabling switchdev mode first time:mlx5_core 0012:03:00.1: E-Switch: Supported tc chains and prios offloadworkqueue: Failed to create a rescuer kthread for wq "mlx5e": -EINTRmlx5_core 0012:03:00.1: mlx5e_netdev_init_profile:6214:(pid 37199): mlx5e_priv_init failed, err=-12mlx5_core 0012:03:00.1 gpu3rdma1: mlx5e_netdev_change_profile: new profile init failed, -12workqueue: Failed to create a rescuer kthread for wq "mlx5e": -EINTRmlx5_core 0012:03:00.1: mlx5e_netdev_init_profile:6214:(pid 37199): mlx5e_priv_init failed, err=-12mlx5_core 0012:03:00.1 gpu3rdma1: mlx5e_netdev_change_profile: failed to rollback to orig profile, -12 ^^^^^^^^mlx5_core 0000:00:03.0: E-Switch: Disable: mode(LEGACY), nvfs(0), necvfs(0), active vports(0) ## retry: Enabling switchdev mode 2nd time:mlx5_core 0000:00:03.0: E-Switch: Supported tc chains and prios offloadBUG: kernel NULL pointer dereference, address: 0000000000000038 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present pagePGD 0 P4D 0Oops: Oops: 0000 [#1] SMP NOPTICPU: 13 UID: 0 PID: 520 Comm: devlink Not tainted 6.18.0-rc4+ #91 PREEMPT(voluntary)Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-2.fc40 04/01/2014RIP: 0010:mlx5e_detach_netdev+0x3c/0x90Code: 50 00 00 f0 80 4f 78 02 48 8b bf e8 07 00 00 48 85 ff 74 16 48 8b 73 78 48 d1 ee 83 e6 01 83 f6 01 40 0f b6 f6 e8 c4 42 00 00 <48> 8b 45 38 48 85 c0 74 08 48 89 df e8 cc 47 40 1e 48 8b bb f0 07RSP: 0018:ffffc90000673890 EFLAGS: 00010246RAX: 0000000000000000 RBX: ffff8881036a89c0 RCX: 0000000000000000RDX: ffff888113f63800 RSI: ffffffff822fe720 RDI: 0000000000000000RBP: 0000000000000000 R08: 0000000000002dcd R09: 0000000000000000R10: ffffc900006738e8 R11: 00000000ffffffff R12: 0000000000000000R13: 0000000000000000 R14: ffff8881036a89c0 R15: 0000000000000000FS: 00007fdfb8384740(0000) GS:ffff88856a9d6000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 0000000000000038 CR3: 0000000112ae0005 CR4: 0000000000370ef0Call Trace: mlx5e_netdev_change_profile+0x45/0xb0 mlx5e_vport_rep_load+0x27b/0x2d0 mlx5_esw_offloads_rep_load+0x72/0xf0 esw_offloads_enable+0x5d0/0x970 mlx5_eswitch_enable_locked+0x349/0x430 ? is_mp_supported+0x57/0xb0 mlx5_devlink_eswitch_mode_set+0x26b/0x430 devlink_nl_eswitch_set_doit+0x6f/0xf0 genl_family_rcv_msg_doit+0xe8/0x140 genl_rcv_msg+0x18b/0x290 ? __pfx_devlink_nl_pre_doit+0x10/0x10 ? __pfx_devlink_nl_eswitch_set_doit+0x10/0x10 ? __pfx_devlink_nl_post_doit+0x10/0x10 ? __pfx_genl_rcv_msg+0x10/0x10 netlink_rcv_skb+0x52/0x100 genl_rcv+0x28/0x40 netlink_unicast+0x282/0x3e0 ? __alloc_skb+0xd6/0x190 netlink_sendmsg+0x1f7/0x430 __sys_sendto+0x213/0x220 ? __sys_recvmsg+0x6a/0xd0 __x64_sys_sendto+0x24/0x30 do_syscall_64+0x50/0x1f0 entry_SYSCALL_64_after_hwframe+0x76/0x7eRIP: 0033:0x7fdfb8495047

Description: In the Linux kernel, the following vulnerability has been resolved:lib/buildid: use __kernel_read() for sleepable contextPrevent a "BUG: unable to handle kernel NULL pointer dereference infilemap_read_folio".For the sleepable context, convert freader to use __kernel_read() insteadof direct page cache access via read_cache_folio(). This simplifies thefaultable code path by using the standard kernel file reading interfacewhich handles all the complexity of reading file data.At the moment we are not changing the code for non-sleepable context whichuses filemap_get_folio() and only succeeds if the target folios arealready in memory and up-to-date. The reason is to keep the patch simpleand easier to backport to stable kernels.Syzbot repro does not crash the kernel anymore and the selftests runsuccessfully.In the follow up we will make __kernel_read() with IOCB_NOWAIT work fornon-sleepable contexts. In addition, I would like to replace thesecretmem check with a more generic approach and will add fstest for thebuildid code.

If request_irq() fails part-way, the rollback loop callsfree_irq() with dev_id set to 'oct', which does not match the originaldev_id and may leave the irqaction registered.This can keep IRQ handlers alive while ioq_vector is later freed duringunwind/teardown, leading to a use-after-free or crash when an interruptfires.Fix the error path to free IRQs with the same ioq_vector dev_id usedduring request_irq().

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.

When the devicereports a single receive queue, rndis_filter_device_add() does notallocate an indirection table, accepting RSS hash key updates in thisstate leads to a hang.Fix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return-EOPNOTSUPP when the table is absent.

During system resume, the I2Ccontroller will be available only after runtime PM is re-enabled(in resume_early()). However, this may be too late for some devices.Wake up the controller in the suspend() callback while runtime PM isstill enabled. The I2C controller will remain available until thesuspend_noirq() callback (pm_runtime_force_suspend()) is called. Duringresume, the I2C controller can be restored by the resume_noirq() callback(pm_runtime_force_resume()). Finally, the resume() callback re-enablesautosuspend. As a result, the I2C controller can remain available untilthe system enters suspend_noirq() and from resume_noirq().

Description: In the Linux kernel, the following vulnerability has been resolved:uacce: ensure safe queue release with state managementDirectly calling `put_queue` carries risks since it cannotguarantee that resources of `uacce_queue` have been fully releasedbeforehand. So adding a `stop_queue` operation for theUACCE_CMD_PUT_Q command and leaving the `put_queue` operation tothe final resource release ensures safety.Queue states are defined as follows:- UACCE_Q_ZOMBIE: Initial state- UACCE_Q_INIT: After opening `uacce`- UACCE_Q_STARTED: After `start` is issued via `ioctl`When executing `poweroff -f` in virt while accelerator are stillworking, `uacce_fops_release` and `uacce_remove` may executeconcurrently. This can cause `uacce_put_queue` within`uacce_fops_release` to access a NULL `ops` pointer. Therefore, addstate checks to prevent accessing freed pointers.

Description: In the Linux kernel, the following vulnerability has been resolved:regmap: Fix race condition in hwspinlock irqsave routinePreviously, the address of the shared member '&map->spinlock_flags' waspassed directly to 'hwspin_lock_timeout_irqsave'. This creates a racecondition where multiple contexts contending for the lock could overwritethe shared flags variable, potentially corrupting the state for thecurrent lock owner.Fix this by using a local stack variable 'flags' to store the IRQ statetemporarily.

Description: In the Linux kernel, the following vulnerability has been resolved:wifi: rsi: Fix memory corruption due to not set vif driver data sizeThe struct ieee80211_vif contains trailing space for vif driver data,when struct ieee80211_vif is allocated, the total memory size that isallocated is sizeof(struct ieee80211_vif) + size of vif driver data.The size of vif driver data is set by each WiFi driver as needed.The RSI911x driver does not set vif driver data size, no trailing spacefor vif driver data is therefore allocated past struct ieee80211_vif .The RSI911x driver does however use the vif driver data to store itsvif driver data structure "struct vif_priv". An access to vif->drv_privleads to access out of struct ieee80211_vif bounds and corruption ofsome memory.In case of the failure observed locally, rsi_mac80211_add_interface()would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;vif_info->vap_id = vap_idx. This write corrupts struct fq_tin memberstruct list_head new_flows . The flow = list_first_entry(head, structfq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogusaddress, which when accessed causes a crash.The trigger is very simple, boot the machine with init=/bin/sh , mountdevtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1","ip link set wlan0 down" and the crash occurs.Fix this by setting the correct size of vif driver data, which is thesize of "struct vif_priv", so that memory is allocated and the drivercan store its driver data in it, instead of corrupting memory aroundit.

Description: In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Avoid truncating memory addressesOn 32-bit machines with CONFIG_ARM_LPAE, it is possible for lowmemallocations to be backed by addresses physical memory above the 32-bitaddress limit, as found while experimenting with larger VMSPLITconfigurations.This caused the qemu virt model to crash in the GICv3 driver, whichallocates the 'itt' object using GFP_KERNEL. Since all memory belowthe 4GB physical address limit is in ZONE_DMA in this configuration,kmalloc() defaults to higher addresses for ZONE_NORMAL, and theITS driver stores the physical address in a 32-bit 'unsigned long'variable.Change the itt_addr variable to the correct phys_addr_t type instead,along with all other variables in this driver that hold a physicaladdress.The gicv5 driver correctly uses u64 variables, while all other irqchipdrivers don't call virt_to_phys or similar interfaces. It's expected thatother device drivers have similar issues, but fixing this one issufficient for booting a virtio based guest.

Description: In the Linux kernel, the following vulnerability has been resolved:mm/hugetlb: fix hugetlb_pmd_shared()Patch series "mm/hugetlb: fixes for PMD table sharing (incl. usingmmu_gather)", v3.One functional fix, one performance regression fix, and two relatedcomment fixes.I cleaned up my prototype I recently shared [1] for the performance fix,deferring most of the cleanups I had in the prototype to a later point. While doing that I identified the other things.The goal of this patch set is to be backported to stable trees "fairly"easily. At least patch #1 and #4.Patch #1 fixes hugetlb_pmd_shared() not detecting any sharingPatch #2 + #3 are simple comment fixes that patch #4 interacts with.Patch #4 is a fix for the reported performance regression due to excessiveIPI broadcasts during fork()+exit().The last patch is all about TLB flushes, IPIs and mmu_gather.Read: complicatedThere are plenty of cleanups in the future to be had + one reasonableoptimization on x86. But that's all out of scope for this series.Runtime tested, with a focus on fixing the performance regression usingthe original reproducer [2] on x86.This patch (of 4):We switched from (wrongly) using the page count to an independent sharedcount. Now, shared page tables have a refcount of 1 (excludingspeculative references) and instead use ptdesc->pt_share_count to identifysharing.We didn't convert hugetlb_pmd_shared(), so right now, we would neverdetect a shared PMD table as such, because sharing/unsharing no longertouches the refcount of a PMD table.Page migration, like mbind() or migrate_pages() would allow for migratingfolios mapped into such shared PMD tables, even though the folios are notexclusive. In smaps we would account them as "private" although they are"shared", and we would be wrongly setting the PM_MMAP_EXCLUSIVE in thepagemap interface.Fix it by properly using ptdesc_pmd_is_shared() in hugetlb_pmd_shared().

This can only occur in unusual (but legitimate) cases where the SVE signal context has either been modified by userspace or was saved in the context of another task (e.g. as with CRIU), as otherwise the presence of an SVE signal context with SVE_SIG_FLAG_SM implies that TIF_SME is already set. While in this state, task_fpsimd_load() will NOT configure SMCR_ELx (leaving some arbitrary value configured in hardware) before restoring SVCR and attempting to restore the streaming mode SVE registers from memory via sve_load_state(). As the value of SMCR_ELx.LEN may be larger than the task's streaming SVE vector length, this may read memory outside of the task's allocated sve_state, reading unrelated data and/or triggering a fault. While this can result in secrets being loaded into streaming SVE registers, these values are never exposed. As TIF_SME is clear, fpsimd_bind_task_to_cpu() will configure CPACR_ELx.SMEN to trap EL0 accesses to streaming mode SVE registers, so these cannot be accessed directly at EL0. As fpsimd_save_user_state() verifies the live vector length before saving (S)SVE state to memory, no secret values can be saved back to memory (and hence cannot be observed via ptrace, signals, etc). When the live vector length doesn't match the expected vector length for the task, fpsimd_save_user_state() will send a fatal SIGKILL signal to the task. Hence the task may be killed after executing userspace for some period of time.(2) Restoring a context with SVE_SIG_FLAG_SM clear does not clear the task's SVCR.SM. If SVCR.SM was set prior to restoring the context, then the task will be left in streaming mode unexpectedly, and some register state will be combined inconsistently, though the task will be left in legitimate state from the kernel's PoV. This can only occur in unusual (but legitimate) cases where ptrace has been used to set SVCR.SM after entry to the sigreturn syscall, as syscall entry clears SVCR.SM. In these cases, the the provided SVE register data will be loaded into the task's sve_state using the non-streaming SVE vector length and the FPSIMD registers will be merged into this using the streaming SVE vector length.Fix (1) by setting TIF_SME when setting SVCR.SM. This also requiresensuring that the task's sme_state has been allocated, but as this couldcontain live ZA state, it should not be zeroed. Fix (2) by clearingSVCR.SM when restoring a SVE signal context with SVE_SIG_FLAG_SM clear.For consistency, I've pulled the manipulation of SVCR, TIF_SVE, TIF_SME,and fp_type earlier, immediately after the allocation ofsve_state/sme_state, before the restore of the actual register state.This makes it easier to ensure that these are always modifiedconsistently, even if a fault is taken while reading the register datafrom the signal context. I do not expect any software to depend on theexact state restored when a fault is taken while reading the context.

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

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: signal: Allocate SSVE storage when restoring ZAThe code to restore a ZA context doesn't attempt to allocate the task'ssve_state before setting TIF_SME. Consequently, restoring a ZA contextcan place a task into an invalid state where TIF_SME is set but thetask's sve_state is NULL.In legitimate but uncommon cases where the ZA signal context was NOTcreated by the kernel in the context of the same task (e.g. if the taskis saved/restored with something like CRIU), we have no guarantee thatsve_state had been allocated previously.

Description: In the Linux kernel, the following vulnerability has been resolved:io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loopCurrently this is checked before running the pending work. Normally thisis quite fine, as work items either end up blocking (which will create anew worker for other items), or they complete fairly quickly. But syzbotreports an issue where io-wq takes seemingly forever to exit, and with abit of debugging, this turns out to be because it queues a bunch of big(2GB - 4096b) reads with a /dev/msr* file. Since this file type doesn'tsupport ->read_iter(), loop_rw_iter() ends up handling them. Each readreturns 16MB of data read, which takes 20 (!!) seconds. With a bunch ofthese pending, processing the whole chain can take a long time. Easilylonger than the syzbot uninterruptible sleep timeout of 140 seconds.This then triggers a complaint off the io-wq exit path:INFO: task syz.4.135:6326 blocked for more than 143 seconds.

Description: In the Linux kernel, the following vulnerability has been resolved:arm64/fpsimd: ptrace: Fix SVE writes on !SME systemsWhen SVE is supported but SME is not supported, a ptrace write to theNT_ARM_SVE regset can place the tracee into an invalid state where(non-streaming) SVE register data is stored in FP_STATE_SVE format butTIF_SVE is clear. This can result in a later warning fromfpsimd_restore_current_state(), e.g. WARNING: CPU: 0 PID: 7214 at arch/arm64/kernel/fpsimd.c:383 fpsimd_restore_current_state+0x50c/0x748When this happens, fpsimd_restore_current_state() will set TIF_SVE,placing the task into the correct state. This occurs before any othercheck of TIF_SVE can possibly occur, as other checks of TIF_SVE onlyhappen while the FPSIMD/SVE/SME state is live. Thus, aside from thewarning, there is no functional issue.This bug was introduced during rework to error handling in commit: 9f8bf718f2923 ("arm64/fpsimd: ptrace: Gracefully handle errors")... where the setting of TIF_SVE was moved into a block which is onlyexecuted when system_supports_sme() is true.Fix this by removing the system_supports_sme() check. This ensures thatTIF_SVE is set for (SVE-formatted) writes to NT_ARM_SVE, at the cost ofunconditionally manipulating the tracee's saved svcr value. Themanipulation of svcr is benign and inexpensive, and we already dosimilar elsewhere (e.g. during signal handling), so I don't think it'sworth guarding this with system_supports_sme() checks.Aside from the above, there is no functional change. The 'type' argumentto sve_set_common() is only set to ARM64_VEC_SME (in ssve_set())) whensystem_supports_sme(), so the ARM64_VEC_SME case in the switch statementis still unreachable when !system_supports_sme(). WhenCONFIG_ARM64_SME=n, the only caller of sve_set_common() is sve_set(),and the compiler can constant-fold for the case where type isARM64_VEC_SVE, removing the logic for other cases.

In this case, thecommand sequence is currently:- SCTP_CMD_PEER_INIT- SCTP_CMD_TIMER_STOP (T1_INIT)- SCTP_CMD_TIMER_START (T1_COOKIE)- SCTP_CMD_NEW_STATE (COOKIE_ECHOED)- SCTP_CMD_ASSOC_SHKEY- SCTP_CMD_GEN_COOKIE_ECHOIf SCTP_CMD_ASSOC_SHKEY fails, asoc->shkey remains NULL, whileasoc->peer.auth_capable and asoc->peer.peer_chunks have already been set bySCTP_CMD_PEER_INIT. This allows a DATA chunk with auth = 1 and shkey = NULLto be queued by sctp_datamsg_from_user().Since command interpretation stops on failure, no COOKIE_ECHO should beensent via SCTP_CMD_GEN_COOKIE_ECHO. However, the T1_COOKIE timer has alreadybeen started, and it may enqueue a COOKIE_ECHO into the outqueue later. Asa result, the DATA chunk can be transmitted together with the COOKIE_ECHOin sctp_outq_flush_data(), leading to the observed issue.Similar to the other places where it calls sctp_auth_asoc_init_active_key()right after sctp_process_init(), this patch moves the SCTP_CMD_ASSOC_SHKEYimmediately after SCTP_CMD_PEER_INIT, before stopping T1_INIT and startingT1_COOKIE. This ensures that if shared key generation fails, authenticatedDATA cannot be sent. It also allows the T1_INIT timer to retransmit INIT,giving the client another chance to process INIT_ACK and retry key setup.

However, in bpf_test_run, we don'ttake this into account, which makes it possible for userspace to supplya metadata size that is too large (taking up the entire headroom).If userspace supplies such a large metadata size in live packet mode,the xdp_update_frame_from_buff() call in xdp_test_run_init_page() callwill fail, after which packet transmission proceeds with anuninitialised frame structure, leading to the usual Bad Stuff.The commit in the Fixes tag fixed a related bug where the second checkin xdp_update_frame_from_buff() could fail, but did not add anyadditional constraints on the metadata size. Complete the fix by addingan additional check on the metadata size. Reorder the checks slightly tomake the logic clearer and add a comment.

Description: In the Linux kernel, the following vulnerability has been resolved:net: fix segmentation of forwarding fraglist GROThis patch enhances GSO segment handling by properly checkingthe SKB_GSO_DODGY flag for frag_list GSO packets, addressinglow throughput issues observed when a station accesses IPv4servers via hotspots with an IPv6-only upstream interface.Specifically, it fixes a bug in GSO segmentation when forwardingGRO packets containing a frag_list. The function skb_segment_listcannot correctly process GRO skbs that have been converted by XLAT,since XLAT only translates the header of the head skb. Consequently,skbs in the frag_list may remain untranslated, resulting in protocolinconsistencies and reduced throughput.To address this, the patch explicitly sets the SKB_GSO_DODGY flagfor GSO packets in XLAT's IPv4/IPv6 protocol translation helpers(bpf_skb_proto_4_to_6 and bpf_skb_proto_6_to_4). This marks GSOpackets as potentially modified after protocol translation. As aresult, GSO segmentation will avoid using skb_segment_list andinstead falls back to skb_segment for packets with the SKB_GSO_DODGYflag. This ensures that only safe and fully translated frag_listpackets are processed by skb_segment_list, resolving protocolinconsistencies and improving throughput when forwarding GRO packetsconverted by XLAT.

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

However, the device is freed before the guardcleanup runs, causing mutex_unlock() to operate on freed memory.Specifically, gpio_virtuser_device_config_group_release() destroysthe mutex and frees the device while still inside the guard(mutex)scope. When the function returns, the guard cleanup invokesmutex_unlock(&dev->lock), resulting in a slab use-after-free.Limit the mutex lifetime by using a scoped_guard() only around theactivation check, so that the lock is released before mutex_destroy()and kfree() are called.

Description: In the Linux kernel, the following vulnerability has been resolved:net: wwan: t7xx: fix potential skb->frags overflow in RX pathWhen receiving data in the DPMAIF RX path,the t7xx_dpmaif_set_frag_to_skb() function addspage fragments to an skb without checking if the number offragments has exceeded MAX_SKB_FRAGS. This could lead to a buffer overflowin skb_shinfo(skb)->frags[] array, corrupting adjacent memory andpotentially causing kernel crashes or other undefined behavior.This issue was identified through static code analysis by comparing with asimilar vulnerability fixed in the mt76 driver commit b102f0c522cf ("mt76:fix array overflow on receiving too many fragments for a packet").The vulnerability could be triggered if the modem firmware sends packetswith excessive fragments. While under normal protocol conditions (MTU 3080bytes, BAT buffer 3584 bytes),a single packet should not require additionalfragments, the kernel should not blindly trust firmware behavior.Malicious, buggy, or compromised firmware could potentially craft packetswith more fragments than the kernel expects.Fix this by adding a bounds check before calling skb_add_rx_frag() toensure nr_frags does not exceed MAX_SKB_FRAGS.The check must be performed before unmapping to avoid a page leakand double DMA unmap during device teardown.

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix NULL pointer dereference in ceph_mds_auth_match()The CephFS kernel client has regression starting from 6.18-rc1.We have issue in ceph_mds_auth_match() if fs_name == NULL: const char fs_name = mdsc->fsc->mount_options->mds_namespace; ... if (auth->match.fs_name && strcmp(auth->match.fs_name, fs_name)) { / fsname mismatch, try next one */ return 0; }Patrick Donnelly suggested that: In summary, we should definitely startdecoding `fs_name` from the MDSMap and do strict authorizations checksagainst it. Note that the `-o mds_namespace=foo` should only be used forselecting the file system to mount and nothing else. It's possibleno mds_namespace is specified but the kernel will mount the onlyfile system that exists which may have name "foo".This patch reworks ceph_mdsmap_decode() and namespace_equals() withthe goal of supporting the suggested concept. Now struct ceph_mdsmapcontains m_fs_name field that receives copy of extracted FS nameby ceph_extract_encoded_string(). For the case of "old" CephFS filesystems, it is used "cephfs" name.[ idryomov: replace redundant %*pE with %s in ceph_mdsmap_decode(), get rid of a series of strlen() calls in ceph_namespace_match(), drop changes to namespace_equals() body to avoid treating empty mds_namespace as equal, drop changes to ceph_mdsc_handle_fsmap() as namespace_equals() isn't an equivalent substitution there ]

Description: In the Linux kernel, the following vulnerability has been resolved:ceph: fix oops due to invalid pointer for kfree() in parse_longname()This fixes a kernel oops when reading ceph snapshot directories (.snap),for example by simply running `ls /mnt/my_ceph/.snap`.The variable str is guarded by __free(kfree), but advanced by one forskipping the initial '_' in snapshot names. Thus, kfree() is calledwith an invalid pointer. This patch removes the need for advancing thepointer so kfree() is called with correct memory pointer.Steps to reproduce:1. Create snapshots on a cephfs volume (I've 63 snaps in my testcase)2. Add cephfs mount to fstab$ echo "samba-fileserver@.files=/volumes/datapool/stuff/3461082b-ecc9-4e82-8549-3fd2590d3fb6 /mnt/test/stuff ceph acl,noatime,_netdev 0 0" >> /etc/fstab3. Reboot the system$ systemctl reboot4. Check if it's really mounted$ mount | grep stuff5. List snapshots (expected 63 snapshots on my system)$ ls /mnt/test/stuff/.snapNow ls hangs forever and the kernel log shows the oops.

For now, just mark RDI/RSI as clobbered for thosetwo calls. This should have a minimal effect on code generation overallas it should be rare for the compiler to want to make RDI/RSI liveacross hypercalls.

Description: In the Linux kernel, the following vulnerability has been resolved:xfs: check for deleted cursors when revalidating two btreesThe free space and inode btree repair functions will rebuild both btreesat the same time, after which it needs to evaluate both btrees toconfirm that the corruptions are gone.However, Jiaming Zhang ran syzbot and produced a crash in the secondxchk_allocbt call. His root-cause analysis is as follows (with minorcorrections): In xrep_revalidate_allocbt(), xchk_allocbt() is called twice (first for BNOBT, second for CNTBT). The cause of this issue is that the first call nullified the cursor required by the second call. Let's first enter xrep_revalidate_allocbt() via following call chain: xfs_file_ioctl() -> xfs_ioc_scrubv_metadata() -> xfs_scrub_metadata() -> `sc->ops->repair_eval(sc)` -> xrep_revalidate_allocbt() xchk_allocbt() is called twice in this function. In the first call: /* Note that sc->sm->sm_type is XFS_SCRUB_TYPE_BNOPT now */ xchk_allocbt() -> xchk_btree() -> `bs->scrub_rec(bs, recp)` -> xchk_allocbt_rec() -> xchk_allocbt_xref() -> xchk_allocbt_xref_other() since sm_type is XFS_SCRUB_TYPE_BNOBT, pur is set to &sc->sa.cnt_cur. Kernel called xfs_alloc_get_rec() and returned -EFSCORRUPTED. Call chain: xfs_alloc_get_rec() -> xfs_btree_get_rec() -> xfs_btree_check_block() -> (XFS_IS_CORRUPT || XFS_TEST_ERROR), the former is false and the latter is true, return -EFSCORRUPTED. This should be caused by ioctl$XFS_IOC_ERROR_INJECTION I guess. Back to xchk_allocbt_xref_other(), after receiving -EFSCORRUPTED from xfs_alloc_get_rec(), kernel called xchk_should_check_xref(). In this function, *curpp (points to sc->sa.cnt_cur) is nullified. Back to xrep_revalidate_allocbt(), since sc->sa.cnt_cur has been nullified, it then triggered null-ptr-deref via xchk_allocbt() (second call) -> xchk_btree().So. The bnobt revalidation failed on a cross-reference attempt, so wedeleted the cntbt cursor, and then crashed when we tried to revalidatethe cntbt. Therefore, check for a null cntbt cursor before thatrevalidation, and mark the repair incomplete. Also we can ignore thesecond tree entirely if the first tree was rebuilt but is alreadycorrupt.Apply the same fix to xrep_revalidate_iallocbt because it has the sameproblem.

Description: In the Linux kernel, the following vulnerability has been resolved:net: gro: fix outer network offsetThe udp GRO complete stage assumes that all the packets inserted the RXhave the `encapsulation` flag zeroed. Such assumption is not true, as afew H/W NICs can set such flag when H/W offloading the checksum foran UDP encapsulated traffic, the tun driver can inject GSO packets withUDP encapsulation and the problematic layout can also be created viaa veth based setup.Due to the above, in the problematic scenarios, udp4_gro_complete() usesthe wrong network offset (inner instead of outer) to compute the outerUDP header pseudo checksum, leading to csum validation errors later onin packet processing.Address the issue always clearing the encapsulation flag at GRO completiontime. Such flag will be set again as needed for encapsulated packets byudp_gro_complete().

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv4: fix ARM64 alignment fault in multipath hash seed`struct sysctl_fib_multipath_hash_seed` contains two u32 fields(user_seed and mp_seed), making it an 8-byte structure with a 4-bytealignment requirement.In `fib_multipath_hash_from_keys()`, the code evaluates the entirestruct atomically via `READ_ONCE()`: mp_seed = READ_ONCE(net->ipv4.sysctl_fib_multipath_hash_seed).mp_seed;While this silently works on GCC by falling back to unaligned regularloads which the ARM64 kernel tolerates, it causes a fatal kernel panicwhen compiled with Clang and LTO enabled.Commit e35123d83ee3 ("arm64: lto: Strengthen READ_ONCE() to acquirewhen CONFIG_LTO=y") strengthens `READ_ONCE()` to use Load-Acquireinstructions (`ldar` / `ldapr`) to prevent compiler reordering bugsunder Clang LTO. Since the macro evaluates the full 8-byte struct,Clang emits a 64-bit `ldar` instruction. ARM64 architecture strictlyrequires `ldar` to be naturally aligned, thus executing it on a 4-bytealigned address triggers a strict Alignment Fault (FSC = 0x21).Fix the read side by moving the `READ_ONCE()` directly to the `u32`member, which emits a safe 32-bit `ldar Wn`.Furthermore, Eric Dumazet pointed out that `WRITE_ONCE()` on the entirestruct in `proc_fib_multipath_hash_set_seed()` is also flawed. Analysisshows that Clang splits this 8-byte write into two separate 32-bit`str` instructions. While this avoids an alignment fault, it destroysatomicity and exposes a tear-write vulnerability. Fix this byexplicitly splitting the write into two 32-bit `WRITE_ONCE()`operations.Finally, add the missing `READ_ONCE()` when reading `user_seed` in`proc_fib_multipath_hash_seed()` to ensure proper pairing andconcurrency safety.

Description: In the Linux kernel, the following vulnerability has been resolved:xsk: Fix fragment node deletion to prevent buffer leakAfter commit b692bf9a7543 ("xsk: Get rid of xdp_buff_xsk::xskb_list_node"),the list_node field is reused for both the xskb pool list and the bufferfree list, this causes a buffer leak as described below.xp_free() checks if a buffer is already on the free list usinglist_empty(&xskb->list_node). When list_del() is used to remove a nodefrom the xskb pool list, it doesn't reinitialize the node pointers.This means list_empty() will return false even after the node has beenremoved, causing xp_free() to incorrectly skip adding the buffer to thefree list.Fix this by using list_del_init() instead of list_del() in all fragmenthandling paths, this ensures the list node is reinitialized after removal,allowing the list_empty() to work correctly.

Description: In the Linux kernel, the following vulnerability has been resolved:mm: thp: deny THP for files on anonymous inodesfile_thp_enabled() incorrectly allows THP for files on anonymous inodes(e.g. guest_memfd and secretmem). These files are created viaalloc_file_pseudo(), which does not call get_write_access() and leavesinode->i_writecount at 0. Combined with S_ISREG(inode->i_mode) beingtrue, they appear as read-only regular files whenCONFIG_READ_ONLY_THP_FOR_FS is enabled, making them eligible for THPcollapse.Anonymous inodes can never pass the inode_is_open_for_write() checksince their i_writecount is never incremented through the normal VFSopen path. The right thing to do is to exclude them from THP eligibilityaltogether, since CONFIG_READ_ONLY_THP_FOR_FS was designed for realfilesystem files (e.g. shared libraries), not for pseudo-filesysteminodes.For guest_memfd, this allows khugepaged and MADV_COLLAPSE to createlarge folios in the page cache via the collapse path, but theguest_memfd fault handler does not support large folios. This triggersWARN_ON_ONCE(folio_test_large(folio)) in kvm_gmem_fault_user_mapping().For secretmem, collapse_file() tries to copy page contents through thedirect map, but secretmem pages are removed from the direct map.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf, arm64: Force 8-byte alignment for JIT buffer to prevent atomic tearingstruct bpf_plt contains a u64 target field. Currently, the BPF JITallocator requests an alignment of 4 bytes (sizeof(u32)) for the JITbuffer.Because the base address of the JIT buffer can be 4-byte aligned (e.g.,ending in 0x4 or 0xc), the relative padding logic in build_plt() failsto ensure that target lands on an 8-byte boundary.This leads to two issues:1. UBSAN reports misaligned-access warnings when dereferencing the structure.2. More critically, target is updated concurrently via WRITE_ONCE() in bpf_arch_text_poke() while the JIT'd code executes ldr. On arm64, 64-bit loads/stores are only guaranteed to be single-copy atomic if they are 64-bit aligned. A misaligned target risks a torn read, causing the JIT to jump to a corrupted address.Fix this by increasing the allocation alignment requirement to 8 bytes(sizeof(u64)) in bpf_jit_binary_pack_alloc(). This anchors the base ofthe JIT buffer to an 8-byte boundary, allowing the relative padding mathin build_plt() to correctly align the target field.

Description: In the Linux kernel, the following vulnerability has been resolved:af_unix: Give up GC if MSG_PEEK intervened.Igor Ushakov reported that GC purged the receive queue ofan alive socket due to a race with MSG_PEEK with a nice repro.This is the exact same issue previously fixed by commitcbcf01128d0a ("af_unix: fix garbage collect vs MSG_PEEK").After GC was replaced with the current algorithm, the citedcommit removed the locking dance in unix_peek_fds() andreintroduced the same issue.The problem is that MSG_PEEK bumps a file refcount withoutinteracting with GC.Consider an SCC containing sk-A and sk-B, where sk-A isclose()d but can be recv()ed via sk-B.The bad thing happens if sk-A is recv()ed with MSG_PEEK fromsk-B and sk-B is close()d while GC is checking unix_vertex_dead()for sk-A and sk-B. GC thread User thread --------- ----------- unix_vertex_dead(sk-A) -> true <------. \ `------ recv(sk-B, MSG_PEEK) invalidate !! -> sk-A's file refcount : 1 -> 2 close(sk-B) -> sk-B's file refcount : 2 -> 1 unix_vertex_dead(sk-B) -> trueInitially, sk-A's file refcount is 1 by the inflight fd in sk-Brecvq. GC thinks sk-A is dead because the file refcount is thesame as the number of its inflight fds.However, sk-A's file refcount is bumped silently by MSG_PEEK,which invalidates the previous evaluation.At this moment, sk-B's file refcount is 2; one by the open fd,and one by the inflight fd in sk-A. The subsequent close()releases one refcount by the former.Finally, GC incorrectly concludes that both sk-A and sk-B are dead.One option is to restore the locking dance in unix_peek_fds(),but we can resolve this more elegantly thanks to the new algorithm.The point is that the issue does not occur without the subsequentclose() and we actually do not need to synchronise MSG_PEEK withthe dead SCC detection.When the issue occurs, close() and GC touch the same file refcount.If GC sees the refcount being decremented by close(), it can justgive up garbage-collecting the SCC.Therefore, we only need to signal the race during MSG_PEEK witha proper memory barrier to make it visible to the GC.Let's use seqcount_t to notify GC when MSG_PEEK occurs and letit defer the SCC to the next run.This way no locking is needed on the MSG_PEEK side, and we canavoid imposing a penalty on every MSG_PEEK unnecessarily.Note that we can retry within unix_scc_dead() if MSG_PEEK isdetected, but we do not do so to avoid hung task splat fromabusive MSG_PEEK calls.

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

Description: systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected.

Description: In the Linux kernel, the following vulnerability has been resolved:net: skb: fix cross-cache free of KFENCE-allocated skb headSKB_SMALL_HEAD_CACHE_SIZE is intentionally set to a non-power-of-2value (e.g. 704 on x86_64) to avoid collisions with generic kmallocbucket sizes. This ensures that skb_kfree_head() can reliably useskb_end_offset to distinguish skb heads allocated fromskb_small_head_cache vs. generic kmalloc caches.However, when KFENCE is enabled, kfence_ksize() returns the exactrequested allocation size instead of the slab bucket size. If a caller(e.g. bpf_test_init) allocates skb head data via kzalloc() and therequested size happens to equal SKB_SMALL_HEAD_CACHE_SIZE, thenslab_build_skb() -> ksize() returns that exact value. After subtractingskb_shared_info overhead, skb_end_offset ends up matchingSKB_SMALL_HEAD_HEADROOM, causing skb_kfree_head() to incorrectly freethe object to skb_small_head_cache instead of back to the originalkmalloc cache, resulting in a slab cross-cache free: kmem_cache_free(skbuff_small_head): Wrong slab cache. Expected skbuff_small_head but got kmalloc-1kFix this by always calling kfree(head) in skb_kfree_head(). This keepsthe free path generic and avoids allocator-specific misclassificationfor KFENCE objects.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: fix use-after-free and NULL deref in smb_grant_oplock()smb_grant_oplock() has two issues in the oplock publication sequence:1) opinfo is linked into ci->m_op_list (via opinfo_add) before add_lease_global_list() is called. If add_lease_global_list() fails (kmalloc returns NULL), the error path frees the opinfo via __free_opinfo() while it is still linked in ci->m_op_list. Concurrent m_op_list readers (opinfo_get_list, or direct iteration in smb_break_all_levII_oplock) dereference the freed node.2) opinfo->o_fp is assigned after add_lease_global_list() publishes the opinfo on the global lease list. A concurrent find_same_lease_key() can walk the lease list and dereference opinfo->o_fp->f_ci while o_fp is still NULL.Fix by restructuring the publication sequence to eliminate post-publishfailure:- Set opinfo->o_fp before any list publication (fixes NULL deref).- Preallocate lease_table via alloc_lease_table() before opinfo_add() so add_lease_global_list() becomes infallible after publication.- Keep the original m_op_list publication order (opinfo_add before lease list) so concurrent opens via same_client_has_lease() and opinfo_get_list() still see the in-flight grant.- Use opinfo_put() instead of __free_opinfo() on err_out so that the RCU-deferred free path is used.This also requires splitting add_lease_global_list() to take apreallocated lease_table and changing its return type from int to void,since it can no longer fail.

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: avoid infinite loops caused by residual dataOn the mkdir/mknod path, when mapping logical blocks to physical blocks,if inserting a new extent into the extent tree fails (in this example,because the file system disabled the huge file feature when marking theinode as dirty), ext4_ext_map_blocks() only calls ext4_free_blocks() toreclaim the physical block without deleting the corresponding data inthe extent tree. This causes subsequent mkdir operations to referencethe previously reclaimed physical block number again, even though thisphysical block is already being used by the xattr block. Therefore, asituation arises where both the directory and xattr are using the samebuffer head block in memory simultaneously.The above causes ext4_xattr_block_set() to enter an infinite loop about"inserted" and cannot release the inode lock, ultimately leading to the143s blocking problem mentioned in [1].If the metadata is corrupted, then trying to remove some extent spacecan do even more harm. Also in case EXT4_GET_BLOCKS_DELALLOC_RESERVEwas passed, remove space wrongly update quota information.Jan Kara suggests distinguishing between two cases:1) The error is ENOSPC or EDQUOT - in this case the filesystem is fullyconsistent and we must maintain its consistency including all theaccounting. However these errors can happen only early before we'veinserted the extent into the extent tree. So current code works correctlyfor this case.2) Some other error - this means metadata is corrupted. We should strive todo as few modifications as possible to limit damage. So I'd just skipfreeing of allocated blocks.[1]INFO: task syz.0.17:5995 blocked for more than 143 seconds.Call Trace: inode_lock_nested include/linux/fs.h:1073 [inline] __start_dirop fs/namei.c:2923 [inline] start_dirop fs/namei.c:2934 [inline]

Description: In the Linux kernel, the following vulnerability has been resolved:ext4: convert inline data to extents when truncate exceeds inline sizeAdd a check in ext4_setattr() to convert files from inline data storageto extent-based storage when truncate() grows the file size beyond theinline capacity. This prevents the filesystem from entering aninconsistent state where the inline data flag is set but the file sizeexceeds what can be stored inline.Without this fix, the following sequence causes a kernel BUG_ON():1. Mount filesystem with inode that has inline flag set and small size2. truncate(file, 50MB) - grows size but inline flag remains set3. sendfile() attempts to write data4. ext4_write_inline_data() hits BUG_ON(write_size > inline_capacity)The crash occurs because ext4_write_inline_data() expects inline storageto accommodate the write, but the actual inline capacity (~60 bytes fori_block + ~96 bytes for xattrs) is far smaller than the file size andwrite request.The fix checks if the new size from setattr exceeds the inode's actualinline capacity (EXT4_I(inode)->i_inline_size) and converts the file toextent-based storage before proceeding with the size change.This addresses the root cause by ensuring the inline data flag and filesize remain consistent during truncate operations.

Description: In the Linux kernel, the following vulnerability has been resolved:ksmbd: fix memory leaks and NULL deref in smb2_lock()smb2_lock() has three error handling issues after list_del() detachessmb_lock from lock_list at no_check_cl:1) If vfs_lock_file() returns an unexpected error in the non-UNLOCK path, goto out leaks smb_lock and its flock because the out: handler only iterates lock_list and rollback_list, neither of which contains the detached smb_lock.2) If vfs_lock_file() returns -ENOENT in the UNLOCK path, goto out leaks smb_lock and flock for the same reason. The error code returned to the dispatcher is also stale.3) In the rollback path, smb_flock_init() can return NULL on allocation failure. The result is dereferenced unconditionally, causing a kernel NULL pointer dereference. Add a NULL check to prevent the crash and clean up the bookkeeping; the VFS lock itself cannot be rolled back without the allocation and will be released at file or connection teardown.Fix cases 1 and 2 by hoisting the locks_free_lock()/kfree() to beforethe if(!rc) check in the UNLOCK branch so all exit paths share onefree site, and by freeing smb_lock and flock before goto out in thenon-UNLOCK branch. Propagate the correct error code in both cases.Fix case 3 by wrapping the VFS unlock in an if(rlock) guard and addinga NULL check for locks_free_lock(rlock) in the shared cleanup.Found via call-graph analysis using sqry.

It shouldn't be invalid since this is a re-insertion, so must haveworked before. Leaving the likely culprit as something already placedwhere we want to insert the vma.Following from that, for the case where we do something like a rebind inthe middle of a vma, and one or both mapped ends are already compatible,we skip doing the rebind of those vma and set next/prev to NULL. As wellas then adjust the original unmap va range, to avoid unmapping the ends.However, if we trigger the unwind path, we end up with three va, withthe two ends never being removed and the original va range in the middlestill being the shrunken size.If this occurs, one failure mode is when another unwind op needs tointeract with that range, which can happen with a vector of binds. Forexample, if we need to re-insert something in place of the original va.In this case the va is still the shrunken version, so when removing itand then doing a re-insert it can overlap with the ends, which werenever removed, triggering a warning like above, plus leaving the vm in abad state.With that, we need two things here: 1) Stop nuking the prev/next tracking for the skip cases. Instead relying on checking for skip prev/next, where needed. That way on the unwind path, we now correctly remove both ends. 2) Undo the unmap va shrinkage, on the unwind path. With the two ends now removed the unmap va should expand back to the original size again, before re-insertion.v2: - Update the explanation in the commit message, based on an actual IGT of triggering this issue, rather than conjecture. - Also undo the unmap shrinkage, for the skip case. With the two ends now removed, the original unmap va range should expand back to the original range.v3: - Track the old start/range separately. vma_size/start() uses the va info directly.(cherry picked from commit aec6969f75afbf4e01fd5fb5850ed3e9c27043ac)

This could lead to race conditions.However, adding mutex protection directly to these functions causesa deadlock because pmbus_regulator_notify() (which callsregulator_notifier_call_chain()) is often called with the mutexalready held (e.g., from pmbus_fault_handler()).

This makes check_resource_leak() to skipvalidation of active_rcu_locks, active_preempt_locks, andactive_irq_id on exception exits from subprogs.At runtime bpf_throw() unwinds the stack via ORC without releasing anyuser-acquired locks, which may cause various issues as the result.Fix by setting check_lock = true for exception exits regardless ofcurframe, since exceptions bypass all intermediate framecleanup. Update the error message prefix to "bpf_throw" for exceptionexits to distinguish them from normal BPF_EXIT.Fix reject_subprog_with_rcu_read_lock test which was previouslypassing for the wrong reason. Test program returned directly from thesubprog call without closing the RCU section, so the error wastriggered by the unclosed RCU lock on normal exit, not bybpf_throw.

Description: A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI (Extensible Firmware Interface) device path node header. A local user could exploit this vulnerability by providing a specially crafted device path node. This can lead to infinite recursion, causing stack exhaustion and a process crash, resulting in a denial of service (DoS).

Description: js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default).

Description: Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, `Rack::Directory` generates an HTML directory index where each file entry is rendered as a clickable link. If a file exists on disk whose basename starts with the `javascript:` scheme (e.g. `javascript:alert(1)`), the generated index contains an anchor whose `href` is exactly `javascript:alert(1)`. Clicking the entry executes JavaScript in the browser (demonstrated with `alert(1)`). Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.

Description: Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf) with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command. The issue has been fixed as of Vim patch v9.1.2148.

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:md: suspend array while updating raid_disks via sysfsIn raid1_reshape(), freeze_array() is called before modifying the r1biomemory pool (conf->r1bio_pool) and conf->raid_disks, andunfreeze_array() is called after the update is completed.However, freeze_array() only waits until nr_sync_pending and(nr_pending - nr_queued) of all buckets reaches zero. When an I/O erroroccurs, nr_queued is increased and the corresponding r1bio is queued toeither retry_list or bio_end_io_list. As a result, freeze_array() mayunblock before these r1bios are released.This can lead to a situation where conf->raid_disks and the mempool havealready been updated while queued r1bios, allocated with the oldraid_disks value, are later released. Consequently, free_r1bio() mayaccess memory out of bounds in put_all_bios() and release r1bios of thewrong size to the new mempool, potentially causing issues with themempool as well.Since only normal I/O might increase nr_queued while an I/O error occurs,suspending the array avoids this issue.Note: Updating raid_disks via ioctl SET_ARRAY_INFO already suspendsthe array. Therefore, we suspend the array when updating raid_disksvia sysfs to avoid this issue too.

Description: HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check if hb_malloc returns NULL before using placement new to construct an object at the returned pointer address. When hb_malloc fails to allocate memory (which can occur in low-memory conditions or when using custom allocators that simulate allocation failures), it returns NULL. The code then attempts to call the constructor on this null pointer using placement new syntax, resulting in undefined behavior and a Segmentation Fault. This issue has been patched in version 12.3.0.

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().

However, the iocb member is defined as a fixed-size 64-bytearray within struct purex_item.If the reported frame_size exceeds 64 bytes, subsequent memcpy calls willoverflow the iocb member boundary. While extra memory might be allocated,this cross-member write is unsafe and triggers warnings underCONFIG_FORTIFY_SOURCE.Fix this by capping total_bytes to the size of the iocb member (64 bytes)before allocation and copying. This ensures all copies remain within thebounds of the destination structure member.

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

Description: Issue summary: An OpenSSL TLS 1.3 server may fail to negotiate the expectedpreferred key exchange group when its key exchange group configuration includesthe default by using the 'DEFAULT' keyword.Impact summary: A less preferred key exchange may be used even when a morepreferred group is supported by both client and server, if the groupwas not included among the client's initial predicated keyshares.This will sometimes be the case with the new hybrid post-quantum groups,if the client chooses to defer their use until specifically requested bythe server.If an OpenSSL TLS 1.3 server's configuration uses the 'DEFAULT' keyword tointerpolate the built-in default group list into its own configuration, perhapsadding or removing specific elements, then an implementation defect causes the'DEFAULT' list to lose its 'tuple' structure, and all server-supported groupswere treated as a single sufficiently secure 'tuple', with the server notsending a Hello Retry Request (HRR) even when a group in a more preferred tuplewas mutually supported.As a result, the client and server might fail to negotiate a mutually supportedpost-quantum key agreement group, such as 'X25519MLKEM768', if the client'sconfiguration results in only 'classical' groups (such as 'X25519' being theonly ones in the client's initial keyshare prediction).OpenSSL 3.5 and later support a new syntax for selecting the most preferred TLS1.3 key agreement group on TLS servers. The old syntax had a single 'flat'list of groups, and treated all the supported groups as sufficiently secure.If any of the keyshares predicted by the client were supported by the serverthe most preferred among these was selected, even if other groups supported bythe client, but not included in the list of predicted keyshares would have beenmore preferred, if included.The new syntax partitions the groups into distinct 'tuples' of roughlyequivalent security. Within each tuple the most preferred group included amongthe client's predicted keyshares is chosen, but if the client supports a groupfrom a more preferred tuple, but did not predict any corresponding keyshares,the server will ask the client to retry the ClientHello (by issuing a HelloRetry Request or HRR) with the most preferred mutually supported group.The above works as expected when the server's configuration uses the built-indefault group list, or explicitly defines its own list by directly defining thevarious desired groups and group 'tuples'.No OpenSSL FIPS modules are affected by this issue, the code in question liesoutside the FIPS boundary.OpenSSL 3.6 and 3.5 are vulnerable to this issue.OpenSSL 3.6 users should upgrade to OpenSSL 3.6.2 once it is released.OpenSSL 3.5 users should upgrade to OpenSSL 3.5.6 once it is released.OpenSSL 3.4, 3.3, 3.0, 1.0.2 and 1.1.1 are not affected by this issue.

Description: In the Linux kernel, the following vulnerability has been resolved:spi: use generic driver_override infrastructureWhen a driver is probed through __driver_attach(), the bus' match()callback is called without the device lock held, thus accessing thedriver_override field without a lock, which can cause a UAF.Fix this by using the driver-core driver_override infrastructure takingcare of proper locking internally.Note that calling match() from __driver_attach() without the device lockheld is intentional. [1]Also note that we do not enable the driver_override feature of structbus_type, as SPI - in contrast to most other buses - passes "" tosysfs_emit() when the driver_override pointer is NULL. Thus, printing"\n" instead of "(null)\n".

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

However, the 'size' argumentdoes not account for this extra byte. The original code then allocated'size' bytes and used strcpy() to copy 'buf', which always writes onebyte past the allocated buffer since strcpy() copies until the NULterminator at index 'size'.Fix this by parsing the 'buf' parameter directly using simple_strtoll()without allocating any intermediate memory or string copying. Thisremoves the overflow while simplifying the code.

Description: A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs, the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result in leaked passwords, such as those found in /etc/shadow while performing authentications.

Description: In the Linux kernel, the following vulnerability has been resolved:octeon_ep: Add SKB allocation failures handling in __octep_oq_process_rx()build_skb() returns NULL in case of a memory allocation failure so handleit inside __octep_oq_process_rx() to avoid NULL pointer dereference.__octep_oq_process_rx() is called during NAPI polling by the driver. Ifskb allocation fails, keep on pulling packets out of the Rx DMA queue: weshouldn't break the polling immediately and thus falsely indicate to theoctep_napi_poll() that the Rx pressure is going down. As there is noassociated skb in this case, don't process the packets and don't push themup the network stack - they are skipped.Helper function is implemented to unmmap/flush all the fragment buffersused by the dropped packet. 'alloc_failures' counter is incremented tomark the skb allocation error in driver statistics.Found by Linux Verification Center (linuxtesting.org) with SVACE.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf: Make sure internal and UAPI bpf_redirect flags don't overlapThe bpf_redirect_info is shared between the SKB and XDP redirect paths,and the two paths use the same numeric flag values in the ri->flagsfield (specifically, BPF_F_BROADCAST == BPF_F_NEXTHOP). This means thatif skb bpf_redirect_neigh() is used with a non-NULL params argument and,subsequently, an XDP redirect is performed using the samebpf_redirect_info struct, the XDP path will get confused and end upcrashing, which syzbot managed to trigger.With the stack-allocated bpf_redirect_info, the structure is no longershared between the SKB and XDP paths, so the crash doesn't happenanymore. However, different code paths using identically-numbered flagvalues in the same struct field still seems like a bit of a mess, sothis patch cleans that up by moving the flag definitions together andredefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlapwith the flags used for XDP. It also adds a BUILD_BUG_ON() check to makesure the overlap is not re-introduced by mistake.

Description: In the Linux kernel, the following vulnerability has been resolved:dmaengine: nbpfaxi: Fix memory corruption in probe()The nbpf->chan[] array is allocated earlier in the nbpf_probe() functionand it has "num_channels" elements. These three loops iterate oneelement farther than they should and corrupt memory.The changes to the second loop are more involved. In this case, we'recopying data from the irqbuf[] array into the nbpf->chan[] array. Ifthe data in irqbuf[i] is the error IRQ then we skip it, so the iteratorsare not in sync. I added a check to ensure that we don't go beyond theend of the irqbuf[] array. I'm pretty sure this can't happen, but itseemed harmless to add a check.On the other hand, after the loop has ended there is a check to ensurethat the "chan" iterator is where we expect it to be. In the originalcode we went one element beyond the end of the array so the iteratorwasn't in the correct place and it would always return -EINVAL. However,now it will always be in the correct place. I deleted the check sincewe know the result.

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().

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.

Inkvaser_usb_remove_interfaces() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in usb_kill_anchored_urbs().Fix the memory leak by anchoring the URB in thekvaser_usb_read_bulk_callback() to the dev->rx_submitted anchor.

Description: In the Linux kernel, the following vulnerability has been resolved:scsi: core: Wake up the error handler when final completions race against each otherThe fragile ordering between marking commands completed or failed sothat the error handler only wakes when the last running commandcompletes or times out has race conditions. These race conditions cancause the SCSI layer to fail to wake the error handler, leaving I/Othrough the SCSI host stuck as the error state cannot advance.First, there is an memory ordering issue within scsi_dec_host_busy().The write which clears SCMD_STATE_INFLIGHT may be reordered with readscounting in scsi_host_busy(). While the local CPU will see its ownwrite, reordering can allow other CPUs in scsi_dec_host_busy() orscsi_eh_inc_host_failed() to see a raised busy count, causing no CPU tosee a host busy equal to the host_failed count.This race condition can be prevented with a memory barrier on the errorpath to force the write to be visible before counting host busycommands.Second, there is a general ordering issue with scsi_eh_inc_host_failed(). Bycounting busy commands before incrementing host_failed, it can race with afinal command in scsi_dec_host_busy(), such that scsi_dec_host_busy() doesnot see host_failed incremented but scsi_eh_inc_host_failed() counts busycommands before SCMD_STATE_INFLIGHT is cleared by scsi_dec_host_busy(),resulting in neither waking the error handler task.This needs the call to scsi_host_busy() to be moved after host_failed isincremented to close the race condition.

The queue_response callback can re-queue and re-submit the same request4. The re-submission reuses the same inline_bio from nvmet_req5. Meanwhile, nvmet_req_bio_put() (called after nvmet_req_complete) invokes bio_uninit() for inline_bio, which sets bio->bi_blkg to NULL6. The re-submitted bio enters submit_bio_noacct_nocheck()7. blk_cgroup_bio_start() dereferences bio->bi_blkg, causing a crash: BUG: kernel NULL pointer dereference, address: 0000000000000028 #PF: supervisor read access in kernel mode RIP: 0010:blk_cgroup_bio_start+0x10/0xd0 Call Trace: submit_bio_noacct_nocheck+0x44/0x250 nvmet_bdev_execute_rw+0x254/0x370 [nvmet] process_one_work+0x193/0x3c0 worker_thread+0x281/0x3a0Fix this by reordering nvmet_bio_done() to call nvmet_req_bio_put()BEFORE nvmet_req_complete().

Description: In the Linux kernel, the following vulnerability has been resolved:mm, shmem: prevent infinite loop on truncate raceWhen truncating a large swap entry, shmem_free_swap() returns 0 when theentry's index doesn't match the given index due to lookup alignment. Thefailure fallback path checks if the entry crosses the end border andaborts when it happens, so truncate won't erase an unexpected entry orrange. But one scenario was ignored.When `index` points to the middle of a large swap entry, and the largeswap entry doesn't go across the end border, find_get_entries() willreturn that large swap entry as the first item in the batch with`indices[0]` equal to `index`. The entry's base index will be smallerthan `indices[0]`, so shmem_free_swap() will fail and return 0 due to the"base < index" check. The code will then call shmem_confirm_swap(), getthe order, check if it crosses the END boundary (which it doesn't), andretry with the same index.The next iteration will find the same entry again at the same index withsame indices, leading to an infinite loop.Fix this by retrying with a round-down index, and abort if the index issmaller than the truncate range.

Description: In the Linux kernel, the following vulnerability has been resolved:KVM: Don't clobber irqfd routing type when deassigning irqfdWhen deassigning a KVM_IRQFD, don't clobber the irqfd's copy of the IRQ'srouting entry as doing so breaks kvm_arch_irq_bypass_del_producer() on x86and arm64, which explicitly look for KVM_IRQ_ROUTING_MSI. Instead, tohandle a concurrent routing update, verify that the irqfd is still activebefore consuming the routing information. As evidenced by the x86 andarm64 bugs, and another bug in kvm_arch_update_irqfd_routing() (see below),clobbering the entry type without notifying arch code is surprising anderror prone.As a bonus, checking that the irqfd is active provides a convenientlocation for documenting _why_ KVM must not consume the routing entry foran irqfd that is in the process of being deassigned: once the irqfd isdeleted from the list (which happens *before* the eventfd is detached), itwill no longer receive updates via kvm_irq_routing_update(), and so KVMcould deliver an event using stale routing information (relative toKVM_SET_GSI_ROUTING returning to userspace).As an even better bonus, explicitly checking for the irqfd being activefixes a similar bug to the one the clobbering is trying to prevent: if anirqfd is deactivated, and then its routing is changed,kvm_irq_routing_update() won't invoke kvm_arch_update_irqfd_routing()(because the irqfd isn't in the list). And so if the irqfd is in bypassmode, IRQs will continue to be posted using the old routing information.As for kvm_arch_irq_bypass_del_producer(), clobbering the routing typeresults in KVM incorrectly keeping the IRQ in bypass mode, which isespecially problematic on AMD as KVM tracks IRQs that are being posted toa vCPU in a list whose lifetime is tied to the irqfd.Without the help of KASAN to detect use-after-free, the most commonsympton on AMD is a NULL pointer deref in amd_iommu_update_ga() due tothe memory for irqfd structure being re-allocated and zeroed, resultingin irqfd->irq_bypass_data being NULL when read byavic_update_iommu_vcpu_affinity(): BUG: kernel NULL pointer dereference, address: 0000000000000018 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 40cf2b9067 P4D 40cf2b9067 PUD 408362a067 PMD 0 Oops: Oops: 0000 [#1] SMP CPU: 6 UID: 0 PID: 40383 Comm: vfio_irq_test Tainted: G U W O 6.19.0-smp--5dddc257e6b2-irqfd #31 NONE Tainted: [U]=USER, [W]=WARN, [O]=OOT_MODULE Hardware name: Google, Inc.

This ensures that if the timeout path has already clearedcurr_xfer, the handler will safely return without dereferencing theNULL pointer.

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

This might lead to bandwidth accountingcorruption, as enqueue_task_dl() won't recognize the lock holder asboosted.The scenario occurs when:1. A DEADLINE task (donor) blocks on a PI mutex held by another DEADLINE task (holder), but the holder doesn't inherit parameters (e.g., it already has a shorter deadline)2. sched_setscheduler() changes the holder from DEADLINE to a lower class while still holding the mutex3. The holder should now inherit DEADLINE parameters from the donor and be enqueued with ENQUEUE_REPLENISH, but this doesn't happenFix the issue by introducing __setscheduler_dl_pi(), which detects whena DEADLINE (proper or boosted) task gets setscheduled to a lowerpriority class. In case, the function makes the task inherit DEADLINEparameters of the donoer (pi_se) and sets ENQUEUE_REPLENISH flag toensure proper bandwidth accounting during the next enqueue operation.

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: There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a "binding signature." RPM does not check the binding signature of subkeys prior to importing them. If an attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data integrity. To exploit this flaw, an attacker must either compromise an RPM repository or convince an administrator to install an untrusted RPM or public key. It is strongly recommended to only use RPMs and public keys from trusted sources.

In both cases zpci_register_ioat()fails with a cc value indicating that the device handle is invalid. Thisis because the device is no longer part of the instance as far as thehypervisor is concerned.Currently this leads to an error return and s390_iommu_attach_device()fails. This triggers the WARN_ON() in __iommu_group_set_domain_nofail()because attaching to the default domain must never fail.With the device fenced by the hypervisor no DMAs to or from memory arepossible and the IOMMU translations have no effect. Proceed as if theregistration was successful and let the hotplug event handling clean upthe device.This is similar to how devices in the error state are handled sincecommit 59bbf596791b ("iommu/s390: Make attach succeed even if the deviceis in error state") except that for removal the domain will not beregistered later. This approach was also previously discussed at thelink.Handle both cases, error state and removal, in a helper which checks ifthe error needs to be propagated or ignored. Avoid magic numbercondition codes by using the pre-existing, but never used, defines forPCI load/store condition codes and rename them to reflect that theyapply to all PCI instructions.

However, eventdetection is not supported for all sensors, and if userspace tries toconfigure accelerometer wakeup events on a sensor device that does notsupport them (e.g. LSM6DS0), st_lsm6dsx_write_event() dereferences a NULLpointer when trying to write to the wakeup register.Define an additional struct iio_chan_spec array whose members have a NULLevent_spec field, and use this array instead of st_lsm6dsx_acc_channels forsensors without event detection capability.

There was a device discovery/fabric scan inprogress. A module unload was issued which set the UNLOADING flag. Aspart of the discovery, after receiving an interrupt a work queue wasscheduled (which involved a work to be queued). Since the UNLOADINGflag is set, the work item was not allocated and the mapped memory hadto be freed. The free occurred in interrupt context leading to systemcrash. Delay the driver unload until the fabric scan is complete toavoid the crash.

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.

Any attempt to access MMIO registersduring this window (e.g., from interrupt handlers or other driver threads)can result in uncompleted PCIe transactions, leading to NMI panics orsystem hangs.To prevent this, set the `no_hw_access` flag to true immediately aftertriggering the reset. This signals other driver components to skipregister accesses while the device is offline.A memory barrier `smp_mb()` is added to ensure the flag update isglobally visible to all cores before the driver enters the sleep/waitstate.(cherry picked from commit 7edb503fe4b6d67f47d8bb0dfafb8e699bb0f8a4)

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: fix panic when IPv4 route references loopback IPv6 nexthopWhen a standalone IPv6 nexthop object is created with a loopback device(e.g., "ip -6 nexthop add id 100 dev lo"), fib6_nh_init() misclassifiesit as a reject route. This is because nexthop objects have no destinationprefix (fc_dst=::), causing fib6_is_reject() to match any loopbacknexthop. The reject path skips fib_nh_common_init(), leavingnhc_pcpu_rth_output unallocated. If an IPv4 route later references thisnexthop, __mkroute_output() dereferences NULL nhc_pcpu_rth_output andpanics.Simplify the check in fib6_nh_init() to only match explicit rejectroutes (RTF_REJECT) instead of using fib6_is_reject(). The loopbackpromotion heuristic in fib6_is_reject() is handled separately byip6_route_info_create_nh(). After this change, the three cases behaveas follows:1. Explicit reject route ("ip -6 route add unreachable 2001:db8::/64"): RTF_REJECT is set, enters reject path, skips fib_nh_common_init(). No behavior change.2. Implicit loopback reject route ("ip -6 route add 2001:db8::/32 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. ip6_route_info_create_nh() still promotes it to reject afterward. nhc_pcpu_rth_output is allocated but unused, which is harmless.3. Standalone nexthop object ("ip -6 nexthop add id 100 dev lo"): RTF_REJECT is not set, takes normal path, fib_nh_common_init() is called. nhc_pcpu_rth_output is properly allocated, fixing the crash when IPv4 routes reference this nexthop.

Description: In the Linux kernel, the following vulnerability has been resolved:bpf/bonding: reject vlan+srcmac xmit_hash_policy change when XDP is loadedbond_option_mode_set() already rejects mode changes that would make aloaded XDP program incompatible via bond_xdp_check(). However,bond_option_xmit_hash_policy_set() has no such guard.For 802.3ad and balance-xor modes, bond_xdp_check() returns false whenxmit_hash_policy is vlan+srcmac, because the 802.1q payload is usuallyabsent due to hardware offload. This means a user can:1. Attach a native XDP program to a bond in 802.3ad/balance-xor mode with a compatible xmit_hash_policy (e.g. layer2+3).2. Change xmit_hash_policy to vlan+srcmac while XDP remains loaded.This leaves bond->xdp_prog set but bond_xdp_check() now returning falsefor the same device. When the bond is later destroyed, dev_xdp_uninstall()calls bond_xdp_set(dev, NULL, NULL) to remove the program, which hitsthe bond_xdp_check() guard and returns -EOPNOTSUPP, triggering:WARN_ON(dev_xdp_install(dev, mode, bpf_op, NULL, 0, NULL))Fix this by rejecting xmit_hash_policy changes to vlan+srcmac when anXDP program is loaded on a bond in 802.3ad or balance-xor mode.commit 39a0876d595b ("net, bonding: Disallow vlan+srcmac with XDP")introduced bond_xdp_check() which returns false for 802.3ad/balance-xormodes when xmit_hash_policy is vlan+srcmac. The check was wired intobond_xdp_set() to reject XDP attachment with an incompatible policy, butthe symmetric path -- preventing xmit_hash_policy from being changed to anincompatible value after XDP is already loaded -- was left unguarded inbond_option_xmit_hash_policy_set().Note:commit 094ee6017ea0 ("bonding: check xdp prog when set bond mode")later added a similar guard to bond_option_mode_set(), butbond_option_xmit_hash_policy_set() remained unprotected.

When thedevice reports zero interfaces (either due to hardware configurationor firmware issues), kcalloc(0, ...) returns ZERO_SIZE_PTR (0x10)instead of NULL.Later in dpaa2_switch_probe(), the NAPI initialization unconditionallyaccesses ethsw->ports[0]->netdev, which attempts to dereferenceZERO_SIZE_PTR (address 0x10), resulting in a kernel panic.Add a check to ensure num_ifs is greater than zero after retrievingdevice attributes.

Description: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, `DirectUploadsController` accepts arbitrary metadata from the client and persists it on the blob. Because internal flags like `identified` and `analyzed` are stored in the same metadata hash, a direct-upload client can set these flags to skip MIME detection and analysis. This allows an attacker to upload arbitrary content while claiming a safe `content_type`, bypassing any validations that rely on Active Storage's automatic content type identification. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.

Store the rfkill pointer in a local variablebefore releasing the lock, then call rfkill_unregister() after releasingdevice_lock.This change is safe because rfkill_fop_write() holds rfkill_global_mutexwhile calling the rfkill callbacks, and rfkill_unregister() also acquiresrfkill_global_mutex before cleanup. Therefore, rfkill_unregister() willwait for any ongoing callback to complete before proceeding, anddevice_del() is only called after rfkill_unregister() returns, preventingany use-after-free.The similar lock ordering in nfc_register_device() (device_lock ->rfkill_global_mutex via rfkill_register) is safe because duringregistration the device is not yet in rfkill_list, so no concurrentrfkill operations can occur on this device.

There's no completion for posted writes, so the writel() mayreturn before the PCI write completes. dw_pcie_ep_raise_msix_irq() alsounmaps the outbound ATU entry used for the PCI write, so the write raceswith the unmap.If the PCI write loses the race with the ATU unmap, the write may corrupthost memory or cause IOMMU errors, e.g., these when running fio with alarger queue depth against nvmet-pci-epf: arm-smmu-v3 fc900000.iommu: 0x0000010000000010 arm-smmu-v3 fc900000.iommu: 0x0000020000000000 arm-smmu-v3 fc900000.iommu: 0x000000090000f040 arm-smmu-v3 fc900000.iommu: 0x0000000000000000 arm-smmu-v3 fc900000.iommu: event: F_TRANSLATION client: 0000:01:00.0 sid: 0x100 ssid: 0x0 iova: 0x90000f040 ipa: 0x0 arm-smmu-v3 fc900000.iommu: unpriv data write s1 "Input address caused fault" stag: 0x0Flush the write by performing a readl() of the same address to ensure thatthe write has reached the destination before the ATU entry is unmapped.The same problem was solved for dw_pcie_ep_raise_msi_irq() in commit8719c64e76bf ("PCI: dwc: ep: Cache MSI outbound iATU mapping"), but thereit was solved by dedicating an outbound iATU only for MSI.

Description: A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.

Description: OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sc_compacttlv_find_tag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag (high nibble) and value length (low nibble). With a 1-byte buffer {0x0A}, the encoded element claims tag=0 and length=10 but no value bytes follow. Calling sc_compacttlv_find_tag with search tag 0x00 returns a pointer equal to buf+1 and outlen=10 without verifying that the claimed value length fits within the remaining buffer. In cases where the sc_compacttlv_find_tag is provided untrusted data (such as being read from cards/files), attackers may be able to influence it to return out-of-bounds pointers leading to downstream memory corruption when subsequent code tries to dereference the pointer. This issue has been patched in version 0.27.0.

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

Description: cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This issue has been patched in version 46.0.6.

Description: AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.

Description: runc is a CLI tool for spawning and running containers according to the OCI specification. runc 1.1.13 and earlier, as well as 1.2.0-rc2 and earlier, can be tricked into creating empty files or directories in arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting a race with `os.MkdirAll`. While this could be used to create empty files, existing files would not be truncated. An attacker must have the ability to start containers using some kind of custom volume configuration. Containers using user namespaces are still affected, but the scope of places an attacker can create inodes can be significantly reduced. Sufficiently strict LSM policies (SELinux/Apparmor) can also in principle block this attack -- we suspect the industry standard SELinux policy may restrict this attack's scope but the exact scope of protection hasn't been analysed. This is exploitable using runc directly as well as through Docker and Kubernetes. The issue is fixed in runc v1.1.14 and v1.2.0-rc3.Some workarounds are available. Using user namespaces restricts this attack fairly significantly such that the attacker can only create inodes in directories that the remapped root user/group has write access to. Unless the root user is remapped to an actualuser on the host (such as with rootless containers that don't use `/etc/sub[ug]id`), this in practice means that an attacker would only be able to create inodes in world-writable directories. A strict enough SELinux or AppArmor policy could in principle also restrict the scope if a specific label is applied to the runc runtime, though neither the extent to which the standard existing policies block this attack nor what exact policies are needed to sufficiently restrict this attack have been thoroughly tested.

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: PAM-PKCS#11 is a Linux-PAM login module that allows a X.509 certificate based user login. In versions 0.6.12 and prior, the pam_pkcs11 module segfaults when a user presses ctrl-c/ctrl-d when they are asked for a PIN. When a user enters no PIN at all, `pam_get_pwd` will never initialize the password buffer pointer and as such `cleanse` will try to dereference an uninitialized pointer. On my system this pointer happens to have the value 3 most of the time when running sudo and as such it will segfault. The most likely impact to a system affected by this issue is an availability impact due to a daemon that uses PAM crashing. As of time of publication, a patch for the issue is unavailable.

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.

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.

Therefore, partialallocation should not be treated as a fatal error.Modify es58x_alloc_rx_urbs() to return 0 if at least one URB has beenallocated, restoring the intended behavior and preventing the leakin es58x_open().

In the complete callbackems_usb_read_bulk_callback(), the URBs are processed and resubmitted. Inems_usb_close() the URBs are freed by callingusb_kill_anchored_urbs(&dev->rx_submitted).However, this does not take into account that the USB framework unanchorsthe URB before the complete function is called. This means that once anin-URB has been completed, it is no longer anchored and is ultimately notreleased in ems_usb_close().Fix the memory leak by anchoring the URB in theems_usb_read_bulk_callback() to the dev->rx_submitted anchor.

Since oct->props[i].netdev is stillNULL at this point, the cleanup function liquidio_destroy_nic_device()will fail to find and free the netdev, resulting in a memory leak.Fix this by initializing oct->props[i].netdev before calling the queuesetup functions.

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.

Description: In the Linux kernel, the following vulnerability has been resolved:net: ipv6: fix field-spanning memcpy warning in AH outputFix field-spanning memcpy warnings in ah6_output() andah6_output_done() where extension headers are copied to/from IPv6address fields, triggering fortify-string warnings about writes beyondthe 16-byte address fields. memcpy: detected field-spanning write (size 40) of single field "&top_iph->saddr" at net/ipv6/ah6.c:439 (size 16) WARNING: CPU: 0 PID: 8838 at net/ipv6/ah6.c:439 ah6_output+0xe7e/0x14e0 net/ipv6/ah6.c:439The warnings are false positives as the extension headers areintentionally placed after the IPv6 header in memory. Fix by properlycopying addresses and extension headers separately, and introducehelper functions to avoid code duplication.
