## Overview

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.

## Affected

- `linux_kernel >= 2.6.35, < 5.15.34`
- `linux_kernel >= 5.16, < 5.16.20`
- `linux_kernel >= 5.17, < 5.17.3`
- `linux_kernel = 2.6.34`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.17.3`
