CVE-2026-80529

A flaw was found in the Linux kernel's XFS filesystem. During dquot recovery, the xlogrecoverdquotcommitpass2 function fails to correctly propagate verification errors. This allows a corrupt quota buffer to be written back to disk, potentially leading to data corruption within the XFS filesystem...

CVE-2026-80530

A flaw was found in the Linux kernel's XFS filesystem. When performing file range exchanges with the XFSEXCHMAPSINO1WRITTEN flag set, the reflink flag can be prematurely cleared from an inode that still manages shared written data. This can lead to data corruption between files that share data...

CVE-2026-80533

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability occurs during the Allocation Group Information AGI repair process, specifically in the xrepiunlinkwalkondiskbucket function. If the buffer verifier fails, a null pointer dereference can occur when attempting to rebuild...

CVE-2026-80532

A flaw was found in the XFS filesystem's online file system check fsck utility within the Linux kernel. The xrepiunlinkresolvebucket function, responsible for reconstructing unlinked inode lists, is vulnerable to an infinite loop. This can occur due to malformed nextunlinked pointers, potentially...

CVE-2026-80534

A flaw was found in the XFS filesystem component of the Linux kernel. The xfsdqgetnextid function fails to release an inode lock ilock if an error occurs during extent reading. This ilock leak can leave the quota inode permanently locked, preventing further quota operations and leading to a denia...

CVE-2026-80536

A flaw was found in the Linux kernel's XFS filesystem. A local attacker, by mounting a specially crafted XFS image, could trigger an out-of-bounds write during log recovery. This vulnerability allows for kernel heap corruption, which could lead to a denial of service or potentially arbitrary code...

CVE-2026-80537

A flaw was found in the Linux kernel's XFS filesystem. An off-by-one error in the rtrefcount btree root level validation allows a local attacker to craft a malicious XFS image. When this image is mounted, it can lead to a slab-out-of-bounds write, causing a kernel panic and a denial of service Do...

CVE-2026-80538

A flaw was found in the XFS filesystem within the Linux kernel. The xfsrtginodeensure function incorrectly handles errors returned by xfsrtginodeload, treating I/O, allocation, or corruption errors as successful operations. This oversight can result in the realtime group inode remaining unset,...

CVE-2026-80531

A flaw was found in the xfs filesystem component of the Linux kernel. This vulnerability is a Use-After-Free UAF issue, which means that the system attempts to use memory after it has been freed, potentially leading to unpredictable behavior. This specific UAF occurs during the creation of...

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-2026-80534

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-2026-80531

CVE-2026-80531 is a Use-After-Free (UAF) in the XFS filesystem component of the Linux kernel, specifically in xrep_tempfile_create on the sc->tempip pointer. The UAF occurs when temporary file creation code fails after sc->tempip has been assigned, leading to a use of freed memory. Red Hat ...
