UBUNTU-CVE-2026-97557

In the Linux kernel, the following vulnerability has been resolved: smb: client: avoid leaking refcount in cifsqueueoplockbreak cifsqueueoplockbreak unconditionally takes a reference on the target file before queueing cifsoplockbreak. Only that work item decreases the reference counter again. If...

UBUNTU-CVE-2026-97571

In the Linux kernel, the following vulnerability has been resolved: bnxten: Propagate TPA buffer allocation failures in bnxtqueuememalloc bnxtalloconetpainfodata returns -ENOMEM as soon as one allocation fails. This leaves the remaining rxr-rxtpa entries zeroed. bnxtqueuememalloc discards that...

CVE-2026-98146

The Linux kernel contains a vulnerability in the accel/amdxdna component. The struct amdxdna_cmd_chain utilizes a flexible array annotated with __counted_by(command_count). Because this structure resides in shared AMDXDNA_BO_SHARE memory, userspace can concurrently modify command_count. If an att...

CVE-2026-98144 accel/amdxdna: put the chained BO when its mapping fails

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: put the chained BO when its mapping fails amdxdnacmdseterror looks up the first BO of a command chain, which takes a reference, and drops it at the end of the function. The mapping of that BO is established in...

CVE-2026-98141

The Linux kernel contains a vulnerability in the ntfs component where the update_reparse_data() function incorrectly ignores the return value of set_reparse_index(). When an index insertion fails, the system removes the written reparse data as cleanup but still returns 0, causing symlink(2) and W...

CVE-2026-98141

In the Linux kernel, the following vulnerability has been resolved: ntfs: propagate reparse index insertion failure updatereparsedata ignores the return value of setreparseindex. When index insertion fails, the code removes the just-written reparse data as cleanup but still returns 0, so symlink2...

EUVD-2026-86969

In the Linux kernel, the following vulnerability has been resolved: ntfs: do not mark the volume clean in syncfs when errors were recorded ntfsputsuper and the remount-read-only path both clear the dirty bit only when NVolErrorsvol is false. ntfssyncfs clears it unconditionally, so any sync on a...

CVE-2026-98114 ksmbd: propagate DACL parsing errors

In the Linux kernel, the following vulnerability has been resolved: ksmbd: propagate DACL parsing errors parsedacl silently accepts truncated ACEs and allocation failures, allowing setinfosec to continue with an incomplete ACL conversion. Return parsing and allocation errors to parsesecdesc so...

CVE-2026-98051 net: bcmasp: fix tx_spb_ring_full() checking same slot cnt times

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix txspbringfull checking same slot cnt times The loop initialised nextindex from intf-txspbindex on every iteration, so incrring always produced the same result and only one slot was ever tested. Move the...

CVE-2026-98028

In the Linux kernel, the following vulnerability has been resolved: eth: nfp: drop the replaced rule from the list when reprogramming fails nfpnetfsadd replaces an existing rule by deleting it from the hardware, decrementing nn-fs.count and programming the new one. If nfpnetfsaddhw fails the old...

EUVD-2026-86798

In the Linux kernel, the following vulnerability has been resolved: x86/cfi: Fix FineIBT hash offset in cfigetfunchash The switch of the FineIBT preamble from "subl $hash, %r10d" to the shorter "subl $hash, %eax" moved the hash immediate from offset 7 to offset 5 of the preamble...

CVE-2026-97944

The Linux kernel contains a flaw in the x86/cfi implementation where the cfi_get_func_hash() function uses an incorrect hard-coded offset for the FineIBT hash. This mismatch occurred because the hash immediate moved from offset 7 to offset 5 during a preamble optimization. Consequently, the BPF J...

CVE-2026-97944 x86/cfi: Fix FineIBT hash offset in cfi_get_func_hash()

In the Linux kernel, the following vulnerability has been resolved: x86/cfi: Fix FineIBT hash offset in cfigetfunchash The switch of the FineIBT preamble from "subl $hash, %r10d" to the shorter "subl $hash, %eax" moved the hash immediate from offset 7 to offset 5 of the preamble...

CVE-2026-97920

In the Linux kernel, the following vulnerability has been resolved: tracing: Keep the entry count when the histogram stats allocation fails printentries uses nentries both as the number of sort entries and as its own return value, so the -ENOMEM it stores when the stats allocation fails overwrite...

CVE-2026-97920

The Linux kernel contains a vulnerability where the print_entries() function incorrectly handles memory allocation failures. When a histogram stats allocation fails, the variable n_entries is overwritten with -ENOMEM. Because tracing_map_destroy_sort_entries() treats this value as an unsigned int...
