This issue was patched in ALSA-2024:2169.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xorg-x11-server-source package and not the xorg-x11-server-source package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed.
