## Overview

An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system.

## Affected

- `linux_kernel >= 5.4, < 5.4.226`
- `linux_kernel >= 5.5, < 5.10.157`
- `linux_kernel >= 5.11, < 5.15.81`
- `linux_kernel >= 5.16, < 6.0.11`
- `linux_kernel = 6.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.0.11`
