## Overview

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

vt: add permission check for KDSKBMETA ioctl

KDSKBMETA modifies keyboard meta mode but lacks the !perm check that all
other keyboard setter ioctls in vt_k_ioctl() enforce, allowing a process
to change meta mode on a non-controlling console without authorization.

## Remediation

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