## Overview

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

pstore/zone: Add a null pointer check to the psz_kmsg_read

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.

## Affected

- `linux_kernel < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.155`
- `linux_kernel >= 5.16, < 6.1.86`
- `linux_kernel >= 6.2, < 6.6.27`
- `linux_kernel >= 6.7, < 6.8.6`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.6`
