CVE-2026-80804

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the XFS file system where the NOFS context is not unconditionally restored in the xfs trans roll() function. When the xfs trans commit() function fails, the NOFS context is cleared but only restored during the success path. This omission leaves the error path without NOFS protection, resulting in a circular lock dependency between xfs nondir ilock class and fs reclaim across different CPUs.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
