## Overview

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

media: bcm2835-unicam: Fix asc leaked in error/remove path

v4l2_async_nf_add_fwnode_remote() allocates the asc, which is freed when
v4l2_async_nf_cleanup() is called.

Call v4l2_async_nf_cleanup() properly in the driver paths.

Discovered with kmemleak after rmmod:

unreferenced object 0xffff000084526b80 (size 64):
  comm "modprobe", pid 185, jiffies 4295013512
