CVE-2026-80529

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

xfs: don't swallow dquot recovery verification errors

xlog_recover_dquot_commit_pass2() validates the recovered dquot with xfs_dqblk_verify() and, on failure, sets error = -EFSCORRUPTED and jumps to out_release. But out_release unconditionally returns 0, so the corruption error is discarded: the caller xlog_recover_items_pass2() sees success, log recovery proceeds as if the dquot were valid, and the corrupt quota buffer can be written back to disk.
