Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved by passing a cred pointer to ceph mds auth match(). This change eliminates a redundant get current cred() call, as ceph mds check access() has already obtained the necessary pointer. As a result, it also fixes a reference leak in ceph mds auth match() by avoiding an additional cred reference.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
