## Overview

In the Linux kernel, the following vulnerability has been resolved:

ceph: fix memory leak in ceph_readdir when note_last_dentry returns error

Reset the last_readdir at the same time, and add a comment explaining
why we don't free last_readdir when dir_emit returns false.

## Affected

- `linux_kernel < 5.10.111`
- `linux_kernel >= 5.11, < 5.15.34`
- `linux_kernel >= 5.16, < 5.16.20`
- `linux_kernel >= 5.17, < 5.17.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.17.3`
