CWE-125  (opens in a new tab)

How to fix?

Upgrade Debian:12 xorg-server to version 2:21.1.7-3+deb12u10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xorg-server package and not the xorg-server package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash.
