CVE-2026-80535

Descripción

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.
