## Overview

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a USB device while calling open(), aka a race condition between ufx_ops_open and ufx_usb_disconnect.

## Affected

- `linux_kernel <= 5.19.12`
- `debian_linux = 10.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
