How to fix?

Upgrade Rocky-Linux:9 xorg-x11-server to version 0:1.20.11-31.el9_6 or higher.
This issue was patched in RLSA-2025:9303.

NVD Description

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

A flaw was found in the X Record extension. The RecordSanityCheckRegisterClients function does not check for an integer overflow when computing request length, which allows a client to bypass length checks.
