NVD Description

Note: Versions mentioned in the description apply only to the upstream tigervnc-server package and not the tigervnc-server package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

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.
