Description OSIDB Bzimport 2025-02-26 03:04:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ceph: fix inode reference leakage in ceph_get_snapdir()

The ceph_get_inode() will search for or insert a new inode into the
hash for the given vino, and return a reference to it. If new is
non-NULL, its reference is consumed.

We should release the reference when in error handing cases.
