CVE-2024-9632: Red Hat Enterprise Linux 10

High severity, CVSS 7.8. EPSS: 0.9% chance of exploitation in the next 30 days.

A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges.
