Details

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

blk-cgroup: fix list corruption from reorder of WRITE ->lqueued

_blkcgrstatflush() can be run anytime, especially when blkcgroupbiostart is being executed.

If WRITE of ->lqueued is re-ordered with READ of 'bisc->lnode.next' in the loop of _blkcgrstatflush(), next_bisc can be assigned with one stat instance being added in blkcgroupbiostart(), then the local list in _blkcgrstat_flush() could be corrupted.

Fix the issue by adding one barrier.
