WID-SEC-2026-0769 · first 18.03.2026 · updated 16.07.2026 · CVSS 7,3
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Red Hat OpenShift ist eine "Platform as a Service" (PaaS) Lösung zur Bereitstellung von Applikationen in der Cloud. Ein Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux und Red Hat OpenShift ausnutzen, um beliebigen Programmcode auszuführen, um einen Denial of Service Angriff durchzuführen, um Dateien zu manipulieren, und um Informationen offenzulegen.
Under what conditions?
The BSI does not name any particular preconditions.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
- einen Denial of Service Angriff durchzuführen
- Dateien zu manipulieren
- Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- Amazon Linux 2
- Red Hat Enterprise Linux
- SUSE Linux
- Oracle Linux
- RESF Rocky Linux
- Red Hat Enterprise Linux capstone <9
- Red Hat Enterprise Linux capstone = 10
- Red Hat OpenShift Container Platform rhcos = 4
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Red Hat Enterprise Linux capstone 9
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.
