Linux Kernel: Mehrere Schwachstellen
WID-SEC-2026-2852 · first 17.08.2026 · updated 29.10.2026 · CVSS 9,8
What it is about
Der Kernel stellt den Kern des Linux Betriebssystems dar. Ein Angreifer kann mehrere Schwachstellen in Linux Kernel ausnutzen, um root Rechte zu erlangen, um einen Denial of Service herbeizuführen oder einen nicht näher spezifizierten Angriff durchzuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- root Rechte zu erlangen
- einen Denial of Service herbeizuführen oder einen nicht näher spezifizierten Angriff durchzuführen
Am I affected?
Affected according to the BSI:
- Debian Linux
- Amazon Linux 2
- Red Hat Enterprise Linux
- IBM QRadar SIEM
- Red Hat OpenShift Container Platform
- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
- Ubuntu Linux
- Oracle Linux
- Open Source Linux Kernel
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.
