Description OSIDB Bzimport 2025-06-18 12:04:25 UTC 
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.
