CVE-2026-80535Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: xfs: don't double-lock when deleting a self-referential directory LOLLM notices that the dirtree scrubber can detect a directory that refers to itself. In this case, it's not correct for the directory tree repair code to try to iolock/ilock both sc->ip and dp, because they're the same inode. Fix this by detecting that corner case and handling it appropriately. When a local user or process attempts to delete a directory that refers to itself, the directory tree repair code incorrectly tries to acquire a lock on the same inode twice. This double-locking issue can lead to system instability or unexpected behavior, potentially resulting in a denial of service (DoS). Red Hat severity: Low — CVSS 5.5…
