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.

A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
