CVE-2024-0229: Xorg-x11-server: reattaching to different master device may lead to out-of-bounds memory access

First published: Wed Jan 03 2024(Updated: )

An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.
