## Overview

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

crypto: scomp - fix req->dst buffer overflow

The req->dst buffer size should be checked before copying from the
scomp_scratch->dst to avoid req->dst buffer overflow problem.

## Affected

- `linux_kernel >= 4.10, < 4.19.306`
- `linux_kernel >= 4.20, < 5.4.268`
- `linux_kernel >= 5.5, < 5.10.209`
- `linux_kernel >= 5.11, < 5.15.148`
- `linux_kernel >= 5.16, < 6.1.75`
- `linux_kernel >= 6.2, < 6.6.14`
- `linux_kernel >= 6.7, < 6.7.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.2`
