## Overview

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

dmaengine: idxd: fix device leaks on compat bind and unbind

Make sure to drop the reference taken when looking up the idxd device as
part of the compat bind and unbind sysfs interface.

## Affected

- `linux_kernel >= 5.15, < 5.15.199`
- `linux_kernel >= 5.16, < 6.1.162`
- `linux_kernel >= 6.2, < 6.6.122`
- `linux_kernel >= 6.7, < 6.12.67`
- `linux_kernel >= 6.13, < 6.18.7`
- `linux_kernel = 6.19`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.18.7`
