## Overview

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

dm snapshot: fix lockup in dm_exception_table_exit

There was reported lockup when we exit a snapshot with many exceptions.
Fix this by adding "cond_resched" to the loop that frees the exceptions.

## Affected

- `linux_kernel < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.154`
- `linux_kernel >= 5.16, < 6.1.84`
- `linux_kernel >= 6.2, < 6.6.24`
- `linux_kernel >= 6.7, < 6.7.12`
- `linux_kernel >= 6.8, < 6.8.3`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.3`
