CVE-2026-80534

CVE-2026-80534 is a lock-leak bug in the XFS filesystem of the Linux kernel. The function xfs_dq_get_next_id() acquires the quota inode ILock before calling xfs_iread_extents() ; if that call fails, the function returns early without releasing the lock, leaving the quota inode permanently locked....

CVE-2026-80535

CVE-2026-80535 affects the Linux kernel XFS file system. The dirtree scrubber can detect a directory that refers to itself; in that case, the directory tree repair code incorrectly attempts to iolock/ilock both sc->ip and dp, which are the same inode, resulting in a double-lock . The fix detec...

CVE-2026-80533

CVE-2026-80533 is a Linux kernel bug in the XFS filesystem's AGI repair path. The function xrep_iunlink_walk_ondisk_bucket walks ragi->sc->sa.agi_bp to rebuild unlinked inode lists, but agi_bp can be null if the buffer verifier fails, causing an out-of-bounds walk. The fix substitutes ragi-...

CVE-2026-80532

CVE-2026-80532 affects the XFS filesystem in the Linux kernel , specifically the online fsck (repair) subsystem. The function xrep_iunlink_resolve_bucket , which reconstructs in-core prev/next unlinked list pointers from disk and memory before relinking lost inodes, is vulnerable to an infinite l...
