## Overview

An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93.

## Affected

- `linux_kernel < 5.6.1`
- `ubuntu_linux = 16.04`
- `ubuntu_linux = 18.04`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.6.1`
