WID-SEC-2025-2586 · first 13.11.2025 · updated 26.10.2026 · CVSS 8,6
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um Informationen offenzulegen und um einen Denial-of-Service-Zustand zu verursachen.
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
- Informationen offenzulegen
- einen Denial-of-Service-Zustand zu verursachen
Am I affected?
Affected according to the BSI:
- Amazon Linux 2
- Red Hat Enterprise Linux
- Fedora Linux
- Oracle Linux
- RESF Rocky Linux
- Red Hat Enterprise Linux 9.6
- Red Hat Enterprise Linux 9
- Red Hat Enterprise Linux 8
- Red Hat Enterprise Linux 10.0
- Red Hat Enterprise Linux 10
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.
