PyTorch: Schwachstelle ermöglicht Denial of Service und Offenlegung von Informationen
WID-SEC-2026-2499 · first 24.07.2026 · updated 24.07.2026 · CVSS 7,1
What it is about
PyTorch ist eine Tensor-Bibliothek für Deep Learning mit GPUs und CPUs. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in PyTorch 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
Am I affected?
Affected according to the BSI:
- Open Source PyTorch Vision
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.
