## Overview

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

fanotify: fix false positive on permission events

fsnotify_get_mark_safe() may return false for a mark on an unrelated group,
which results in bypassing the permission check.

Fix by skipping over detached marks that are not in the current group.

## Affected

- `linux_kernel >= 4.12, < 5.10.258`
- `linux_kernel >= 5.11, < 5.15.209`
- `linux_kernel >= 5.16, < 6.1.175`
- `linux_kernel >= 6.2, < 6.6.140`
- `linux_kernel >= 6.7, < 6.12.88`
- `linux_kernel >= 6.13, < 6.18.30`
- `linux_kernel >= 6.19, < 7.0.7`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.7`
