Summary

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

ceph: don't leak snap_rwsem in handle_cap_grant

When handle_cap_grant is called on an IMPORT op, then the snap_rwsem is held and the function is expected to release it before returning. It currently fails to do that in all cases which could lead to a deadlock.
