In the Linux kernel, the following vulnerability has been resolved:
IB/cm: Drop lockdep assert and WARN when freeing old msg
The send completion handler can run after cm_id has advanced to another
message. The cm_id lock is not needed in this case, but a recent change
re-used cm_free_priv_msg(), which asserts that the lock is held and
WARNs if the cm_id's currently outstanding msg is different than the one
being freed.
