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

xfs: avoid dereferencing log items after push callbacks

After xfsaild_push_item() calls iop_push(), the log item may have been

freed if the AIL lock was dropped during the push. Background inode

reclaim or the dquot shrinker can free the log item while the AIL lock

is not held, and the tracepoints in the switch statement dereference

the log item after iop_push() returns.

Fix this by capturing the log item type, flags, and LSN before calling

xfsaild_push_item(), and introducing a new xfs_ail_push_class trace

event class that takes these pre-captured values and the ailp pointer

instead of the log item pointer. (NVD)
