WID-SEC-2026-3382 · first 16.09.2026 · updated 13.10.2026 · CVSS 7,3
What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein lokaler Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um beliebigen Code auszuführen, einschließlich der Ausführung von Code mit Root-Rechten, um Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren oder einen Denial-of-Service-Zustand auszulösen.
Under what conditions?
Only with access to the device or an account on it. Often the second step after a phishing email.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Code auszuführen
- einschließlich der Ausführung von Code mit Root-Rechten
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren oder einen Denial-of-Service-Zustand auszulösen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- RESF Rocky Linux
- Ubuntu Linux
- Oracle Linux
- Red Hat Enterprise Linux 9
- Red Hat Enterprise Linux 9.6 Extended Update Support
- 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.
