WID-SEC-2026-4024 · first 19.10.2026 · updated 29.10.2026 · CVSS 7,5
What it is about
Red Hat Quay ist eine verteilte und hochverfügbare Container Image Registry. Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Quay und Red Hat Enterprise Linux ausnutzen, um einen Denial of Service Angriff durchzuführen oder Sicherheitsmaßnahmen zu umgehen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen oder Sicherheitsmaßnahmen zu umgehen
Am I affected?

- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
- Oracle Linux
- Red Hat Quay
- Red Hat Enterprise Linux 9
- Red Hat Enterprise Linux 10
- Red Hat Enterprise Linux 8
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Install the updates provided by the vendor; details in the sources below.
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
