CVE ID         : CVE-2021-3472

Jan-Niklas Sohn discovered that missing input sanitising in the XInput
extension of the X.org X server may result in privilege escalation if
the X server is running privileged.

For the stable distribution (buster), this problem has been fixed in
version 2:1.20.4-1+deb10u3.

We recommend that you upgrade your xorg-server packages.
