## Overview

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

staging: rtl8723bs: rtw_mlme: add bounds checks before ie_length subtraction

Add guards to ensure ie_length is large enough before subtracting
fixed IE offsets to prevent unsigned integer underflow.

## Affected

- `linux_kernel >= 5.15, < 7.0.13`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.13`
