CVE-2024-0408

MEDIUM

5.5

CVSS v3

Description

A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.

Common questions

How do I fix CVE-2024-0408?

Published advisories record a fix for 43 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.

Is CVE-2024-0408 being actively exploited?

Not that we know of. CVE-2024-0408 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.32% is the estimated probability that it will be exploited in the next 30 days. That is higher than 25% of all scored CVEs.

How severe is CVE-2024-0408?

CVE-2024-0408 has a CVSS v3 base score of 5.5, rated medium. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2024-0408 affect?

Published advisories record a fix for xorg-server (Debian), xorg-x11-server (Red Hat / RHEL), xorg-x11-server (Rocky), xorg-x11-server-Xdmx (Rocky), and 39 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
