Linux Kernel: Mehrere Schwachstellen
WID-SEC-2026-4152 · first 26.10.2026 · updated 26.10.2026 · CVSS 7,3
What it is about
Der Kernel stellt den Kern des Linux Betriebssystems dar. Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, möglicherweise einen Denial-of-Service-Angriff auszulösen, Daten zu manipulieren oder offenzulegen oder Sicherheitsmaßnahmen zu umgehen.
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
- einen nicht näher spezifizierten Angriff durchzuführen
- möglicherweise einen Denial-of-Service-Angriff auszulösen
- Daten zu manipulieren oder offenzulegen oder Sicherheitsmaßnahmen zu umgehen
Am I affected?
Affected according to the BSI:
- 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.
