What it is about
Podman Desktop ist eine Open-Source-Anwendung zur Verwaltung von Containern und Kubernetes-Umgebungen auf dem Desktop. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Podman Desktop ausnutzen, um einen Denial of Service Angriff durchzuführen, und um Informationen offenzulegen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen
- Informationen offenzulegen

Affected according to the BSI:
- Red Hat Enterprise Linux

The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Podman Desktop 1.26.2
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.
