CVE-2026-80805

A flaw was found in the Linux kernel's XFS filesystem. The xfsattr3leafverifyentry function fails to validate an attribute entry pointer before accessing its fields. A local attacker could exploit this by crafting a malicious attribute index nameidx to cause an out-of-bounds read. This could lead...

kernel: xfs: bounds-check buffer log item's dirty bitmap

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...

kernel: xfs: fix exchange-range reflink flag clearing issue with INO1_WRITTEN

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...

Astra Linux – vulnerability in linux-6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: do not irele after failing to iget in xfsattrirecoverwork xlogrecoveryiget never sets @ip to a valid pointer if it returns an error; thus, this irele will cause a dereferencing of a dangling pointer. Fix that issue...

Astra Linux – vulnerability in linux-6.1, linux-6.12

In the Linux kernel, the following vulnerability has been resolved: xfs: save ailp before dropping the AIL lock in push callbacks In xfsinodeitempush and xfsqmdquotlogitempush, the AIL lock is dropped to perform buffer IO. Once the cluster buffer no longer protects the log item from reclaim, the...
