Red Hat Enterprise Linux (freeipmi): Schwachstelle ermöglicht Codeausführung
WID-SEC-2026-1350 · first 05.05.2026 · updated 21.09.2026 · CVSS 8,8
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Red Hat Enterprise Linux ausnutzen, um einen Denial-of-Service-Zustand zu verursachen oder eine Speicherbeschädigung zu erreichen, wodurch möglicherweise die Ausführung von beliebigem Code ermöglicht wird.
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-Zustand zu verursachen oder eine Speicherbeschädigung zu erreichen
- wodurch möglicherweise die Ausführung von beliebigem Code ermöglicht wird
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Fedora Linux
- SUSE Linux
- Oracle Linux
- RESF Rocky Linux
- Red Hat Enterprise Linux 10
- Ubuntu Linux
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.
