## Overview

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

habanalabs: fix possible memory leak in MMU DR fini

This patch fixes what seems to be copy paste error.

We will have a memory leak if the host-resident shadow is NULL (which
will likely happen as the DR and HR are not dependent).

## Affected

- `linux_kernel < 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`
