What it is about

Der Kernel stellt den Kern des Linux Betriebssystems dar. Ein lokaler Angreifer kann eine Schwachstelle im Linux Kernel ausnutzen, um einen Denial of Service Angriff durchzuführen oder um beliebigen Code auszuführen.

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

  • einen Denial of Service Angriff durchzuführen oder um beliebigen Code auszuführen

Am I affected?

Affected according to the BSI:

  • Debian Linux
  • Amazon Linux 2
  • Ubuntu Linux
  • SUSE Linux
  • Oracle Linux
  • EMC Avamar
  • Dell NetWorker
  • SUSE openSUSE
  • Open Source Linux Kernel
  • Dell ECS <3.8.1.1

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Dell ECS 3.8.1.1

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.
