docker: Mehrere Schwachstellen
WID-SEC-2026-0873 · first 26.03.2026 · updated 23.09.2026 · CVSS 8,8
What it is about
Docker ist eine Open-Source-Software, die dazu verwendet werden kann, Anwendungen mithilfe von Betriebssystemvirtualisierung in Containern zu isolieren. Ein lokaler Angreifer kann mehrere Schwachstellen in docker ausnutzen, um Sicherheitsvorkehrungen zu umgehen und Informationen offenzulegen.
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
- Sicherheitsvorkehrungen zu umgehen
- Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- Google Container-Optimized OS
- Debian Linux
- Amazon Linux 2
- Red Hat Enterprise Linux
- Fedora Linux
- Ubuntu Linux
- SUSE Linux
- SUSE openSUSE
- IBM MQ operator
- Red Hat OpenShift API for Data Protection
- Open Source docker <v29.3.1
- Red Hat OpenShift Service Mesh <3.1.7
and 2 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source docker v29.3.1
- Red Hat OpenShift Service Mesh 3.1.7
- Red Hat Enterprise Linux Multicluster Global Hub 1.5.4
- Dell Secure Connect Gateway 5.36.00.16
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.
