## Overview

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

ext4: avoid allocating blocks from corrupted group in ext4_mb_find_by_goal()

Places the logic for checking if the group's block bitmap is corrupt under
the protection of the group lock to avoid allocating blocks from the group
with a corrupted block bitmap.

## Affected

- `linux_kernel < 4.19.308`
- `linux_kernel >= 4.20, < 5.4.270`
- `linux_kernel >= 5.5, < 5.10.211`
- `linux_kernel >= 5.11, < 5.15.150`
- `linux_kernel >= 5.16, < 6.1.80`
- `linux_kernel >= 6.2, < 6.6.19`
- `linux_kernel >= 6.7, < 6.7.7`
- `linux_kernel = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.7`
