NVD Description

Note: Versions mentioned in the description apply only to the upstream xwayland package and not the xwayland package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
