## Overview

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

staging: vchiq_core: handle NULL result of find_service_by_handle

In case of an invalid handle the function find_servive_by_handle
returns NULL. So take care of this and avoid a NULL pointer dereference.

## 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`
