NVD Description

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