  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nxfs: don't swallow dquot recovery verification errors\nxlog_recover_dquot_commit_pass2() validates the recovered dquot with\nxfs_dqblk_verify() and, on failure, sets error = -EFSCORRUPTED and jumps\nto out_release.  But out_release unconditionally returns 0, so the\ncorruption error is discarded: the caller xlog_recover_items_pass2()\nsees success, log recovery proceeds as if the dquot were valid, and the\ncorrupt quota buffer can be written back to disk.", "A flaw was found in the Linux kernel's XFS filesystem. During dquot recovery, the `xlog_recover_dquot_commit_pass2()` function fails to correctly propagate verification errors. This allows a corrupt quota buffer to be written back to disk, potentially leading to data corruption within the XFS filesystem." ],
