## Overview

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

media: atomisp: Fix use after free in atomisp_alloc_css_stat_bufs()

The "s3a_buf" is freed along with all the other items on the
"asd->s3a_stats" list.  It leads to a double free and a use after free.

## Affected

- `linux_kernel >= 5.8, < 5.10.37`
- `linux_kernel >= 5.11, < 5.11.21`
- `linux_kernel >= 5.12, < 5.12.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.12.4`
