## Overview

A use-after-free flaw was found in the Linux kernel’s Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system.

## Affected

- `linux_kernel >= 2.6.35, < 4.14.291`
- `linux_kernel >= 4.15, < 4.19.256`
- `linux_kernel >= 4.20, < 5.4.211`
- `linux_kernel >= 5.5, < 5.10.137`
- `linux_kernel >= 5.11, < 5.15.61`
- `linux_kernel >= 5.16, < 5.18.18`
- `linux_kernel >= 5.19, < 5.19.2`
- `debian_linux = 10.0`
- `h410c_firmware`
- `h300s_firmware`
- `h500s_firmware`
- `h700s_firmware`
- `h300e_firmware`
- `h500e_firmware`
- `h700e_firmware`
- `h410s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.2`
