## Overview

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

crypto: bcm - Fix pointer arithmetic

In spu2_dump_omd() value of ptr is increased by ciph_key_len
instead of hash_iv_len which could lead to going beyond the
buffer boundaries.
Fix this bug by changing ciph_key_len to hash_iv_len.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

## Affected

- `linux_kernel >= 4.11, < 4.19.316`
- `linux_kernel >= 4.20, < 5.4.278`
- `linux_kernel >= 5.5, < 5.10.219`
- `linux_kernel >= 5.11, < 5.15.161`
- `linux_kernel >= 5.16, < 6.1.93`
- `linux_kernel >= 6.2, < 6.6.33`
- `linux_kernel >= 6.7, < 6.8.12`
- `linux_kernel >= 6.9, < 6.9.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.3`
