In the Linux kernel, the following vulnerability has been resolved:ceph: pass cred pointer to ceph_mds_auth_match()This eliminates a redundant get_current_cred() call, becauseceph_mds_check_access() has already obtained this pointer.As a side effect, this also fixes a reference leak inceph_mds_auth_match(): by omitting the get_current_cred() call, noadditional cred reference is taken.
