## Overview

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

dmaengine: ti: dma-crossbar: fix device leak on am335x route allocation

Make sure to drop the reference taken when looking up the crossbar
platform device during am335x route allocation.

## Affected

- `linux_kernel >= 4.4.1, < 5.10.249`
- `linux_kernel >= 5.11, < 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 = 4.4`
- `linux_kernel = 6.19`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.18.7`
