## Overview

An out-of-bounds (OOB) memory write flaw was found in the Linux kernel’s watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system.

## Affected

- `linux_kernel >= 5.8, < 5.10.106`
- `linux_kernel >= 5.11, < 5.15.29`
- `linux_kernel >= 5.16, < 5.16.5`
- `linux_kernel = 5.17`
- `fedora = 35`
- `h300e_firmware`
- `h300s_firmware`
- `h410c_firmware`
- `h410s_firmware`
- `h500e_firmware`
- `h500s_firmware`
- `h610c_firmware`
- `h610s_firmware`
- `h615c_firmware`
- `h700e_firmware`
- `h700s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.16.5`
