Summary
kernel security update
Details
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
udf: Detect system inodes linked into directory hierarchy
When UDF filesystem is corrupted, hidden system inodes can be linked into directory hierarchy which is an avenue for further serious corruption of the filesystem and kernel confusion as noticed by syzbot fuzzed images. Refuse to access system inodes linked into directory hierarchy and vice versa.(CVE-2023-53695)
In the Linux kernel, a boundary check vulnerability exists in the SCSI SES (SCSI Enclosure Services) component. The vulnerability involves improper boundary checking of the addl_desc_ptr pointer in the ses_enclosure_data_process() function, which may lead to out-of-bounds accesses.(CVE-2023-7324)
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg
Issuing two writes to the same af_alg socket is bogus as the data will be interleaved in an unpredictable fashion. Furthermore, concurrent writes may create inconsistencies in the internal socket state.
Disallow this by adding a new ctx->write field that indiciates exclusive ownership for writing.(CVE-2025-39964)
Severity
5.5 (Medium)

The follow-on races against the unlocked udf_try_read_meta()/inode_bmap() walk are also attacker-driven from two of the attacker\u0027s own threads.\nPR:L - udf is FS_REQUIRES_DEV without FS_USERNS_MOUNT, but the realistic delivery is a low-privileged local user\u0027s removable disc/USB/ISO auto-mounted by udisks2 on desktops, kiosks and shared workstations; every subsequent step (open, unlink, ftruncate, write on the exposed system inode) needs only ordinary unprivileged file access.\nUI:N - In the auto-mount scenario the attacker inserts the media and performs all filesystem operations themselves, so no separate victim action is required.\nS:U - The corruption and crash stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Exposing a system inode as a normal file lets the attacker mutate its extent list while udf_try_read_meta() walks it with no i_data_sem held, yielding out-of-bounds reads past the i_data kmalloc buffer and parsing of freed/reallocated blocks, so kernel heap contents can be surfaced through ordinary file reads.\nI:H - The same inode is simultaneously the kernel\u0027s internal block-translation table and a user-writable file, so writes and truncates rewrite in-use metadata mappings, and udf_free_inode()/udf_free_blocks() releases blocks the superblock is still using \u2014 unsynchronized modification of live kernel filesystem state that is exploitable for further memory corruption.\nA:H - syzbot reproduced a kernel WARNING in udf_free_inode() via udf_evict_inode() (udf_updated_lvid, which also carries a BUG_ON), which panics under panic_on_warn, and the resulting metadata-mapping corruption cascades into further oopses."

"value": "AV:A - The malformed data is the SES page 10 payload returned by the enclosure target over the storage fabric (SAS expander/enclosure, FC, or iSCSI/SRP target), so a rogue or compromised device on the SAN segment reaches the parser without local access. This matches the CNA\u0027s treatment of fabric-supplied OOB reads such as CVE-2026-31464 and CVE-2026-63889; a malicious USB device asserting the EncServ INQUIRY bit is an additional, less severe path.\nAC:L - The attacker fully controls both the page 10 length field and its contents, so simply reporting a page length of 0 while advertising DEVICE/ARRAY_DEVICE elements in page 1 deterministically drives addl_desc_ptr past the end of the allocation. No race, timing, or uncontrolled memory-layout condition is involved.\nPR:N - ses_intf_add() runs automatically during SCSI LUN discovery/rescan and binds to any target that sets the EncServ bit in its own INQUIRY response, so no credentials or prior authorization on the host are required. The KASAN report in the companion fix was triggered by systemd-udevd during ordinary enumeration.\nUI:N - Enclosure probing is driven by the kernel\u0027s automatic device discovery on link-up/hotplug and on session re-establishment, not by any operator action. No mount, open, or configuration step by a victim is needed.\nS:U - The out-of-bounds read stays within the kernel\u0027s own slab memory and the resulting data is exposed through the kernel\u0027s enclosure sysfs interface. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Adjacent slab memory is read out of bounds and the bytes are retained in ecomp-\u003eslot and scomp-\u003eaddr, with slot exported through the world-readable /sys/class/enclosure/*/*/slot attribute, giving a repeatable heap-adjacency oracle usable to disclose kernel heap contents and defeat layout randomization. Repeated re-probes let the attacker sample different heap neighbours.\nI:N - The defect is strictly a read overrun \u2014 ses_process_descriptor() only loads from the descriptor and writes to in-bounds fields, so there is no out-of-bounds write or control-flow primitive. Any wrong slot/address value reported is something a malicious enclosure could already report through well-formed data.\nA:H - The read can extend past the end of a page-sized page10 allocation into an adjacent frame, oopsing on configurations where that frame is unmapped (DEBUG_PAGEALLOC/KFENCE, memory holes), and trips a KASAN slab-out-of-bounds report that panics hosts running panic_on_warn. The attacker can force this on every discovery cycle."

Title
crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg
Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg
Issuing two writes to the same af_alg socket is bogus as the
data will be interleaved in an unpredictable fashion. Furthermore,
concurrent writes may create inconsistencies in the internal
socket state.
Disallow this by adding a new ctx->write field that indiciates
exclusive ownership for writing.

{
"lang": "en",
"value": "AV:L - The vulnerability is reached through the AF_ALG socket family via `socket()`/`bind()`/`sendmsg()`/`recvmsg()` syscalls, which requires local system access. There is no remote or adjacent-network path to `af_alg_sendmsg()`.\nAC:L - The attacker controls both sides of the race entirely \u2014 two of its own threads on a socket it owns \u2014 and can force writer A to park deterministically in `af_alg_wait_for_wmem()` by sizing `SO_SNDBUF` and filling it, then wake it on demand with its own `recvmsg()`. The error exit that leaves `cur == 0` is triggered at will with a deliberately faulting user buffer, so no condition is outside the attacker\u0027s control.\nPR:L - `alg_create()`, `alg_bind()` and `alg_setkey()` perform no capability checks whatsoever, so any unprivileged local user \u2014 including one inside a container or unprivileged user namespace \u2014 can open, bind and write to an AF_ALG skcipher/aead socket. The required modules are auto-loaded on demand via `MODULE_ALIAS_NETPROTO(AF_ALG)` and `request_module(\"algif-%s\")`.\nUI:N - The attacking process performs every step itself \u2014 socket creation, bind, and the two concurrent `sendmsg()` calls. No victim action or interaction of any kind is needed.\nS:U - The corruption is confined to kernel heap objects (`struct af_alg_tsgl`/scatterlist and adjacent slab memory) within the same security authority. No hypervisor, IOMMU, or other trust boundary is crossed.\nC:H - The out-of-bounds scatterlist entry is fabricated from kernel list pointers and is subsequently handed to the cipher by `skcipher_recvmsg`/`aead_recvmsg` via `af_alg_pull_tsgl()`, so arbitrary kernel memory is encrypted/decrypted and returned to userspace. This yields a kernel memory disclosure primitive, not merely a pointer leak.\nI:H - `memcpy_from_msg(page_address(sg_page(sg)) + sg-\u003eoffset + sg-\u003elength, msg, len)` on the underflowed scatterlist writes attacker-controlled data of attacker-chosen length to an address derived from attacker-influenceable heap contents. Combined with heap grooming of the 4KB tsgl allocations, this is a controlled kernel write suitable for privilege escalation.\nA:H - Dereferencing `page_address(sg_page(sg))` on a bogus page_link, and the later `put_page()` on that fabricated page, reliably produce an oops/panic or page refcount corruption. Any unprivileged user can trigger this repeatedly, crashing the machine."
