WID-SEC-2024-1227 · first 23.05.2024 · updated 10.08.2026 · CVSS 5,9
What it is about
Der Kernel stellt den Kern des Linux Betriebssystems dar. Ein lokaler Angreifer kann mehrere Schwachstellen in der Bluetooth-Komponente des Linux Kernels ausnutzen, um einen Denial of Service Angriff durchzuführen oder einen nicht spezifizierten Angriff durchzuführen.
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 einen nicht spezifizierten Angriff durchzuführen
Am I affected?
Affected according to the BSI:
- Debian Linux
- Red Hat Enterprise Linux
- Ubuntu Linux
- SUSE Linux
- Open Source Linux Kernel <6.6.31
- Open Source Linux Kernel <6.8.10
- Open Source Linux Kernel <6.9
- Open Source Linux Kernel <6.1.91
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Linux Kernel 6.6.31
- Open Source Linux Kernel 6.8.10
- Open Source Linux Kernel 6.9
- Open Source Linux Kernel 6.1.91
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.
