CVE-2026-80529 in Linux
Resumen
por MITRE • 2026-08-26
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.
Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
