Linux Kernel Ceph Component Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Ceph component of the Linux kernel. This issue arises in the 'ceph_readdir' function when 'note_last_dentry' returns an error. The vulnerability causes the 'last_readdir' variable to retain a reference that is not properly freed, leading to a memory leak.

Impact

Exploitation of this vulnerability causes a memory leak, which can lead to increased memory usage and potential exhaustion of system resources over time.
