CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's XFS filesystem, specifically in the handling of transaction commits where the NOFS context is not restored on error paths. This oversight can lead to a circular lock dependency, potentially causing deadlocks during filesystem operations. System administrators and developers managing Linux environments with XFS should prioritize applying the fix to prevent potential system instability and performance degradation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: xfs: restore nofs context unconditionally in xfs_trans_roll When __xfs_trans_commit() fails in xfs_trans_roll(), the NOFS context is cleared but only restored in the success path. This leaves the error path without nofs protection, causing a circular lock dependency between xfs_nondir_ilock_class and fs_reclaim: CPU0 CPU1 ---- ---- lock(&xfs_nondir_ilock_class); lock(fs_reclaim); lock(&xfs_nondir_ilock_class); lock(fs_reclaim); Fix this by moving xfs_trans_set_context() before the error check so that nofs context is always restored on the new transaction.
