Produktbeschreibung: Der Kernel stellt den Kern des Linux Betriebssystems dar.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux
Im Linux Kernel existieren mehrere Schwachstellen aufgrund von fehlenden Kontrollen zu verschiedenen Feldern in der Komponente "KVM". Die betroffenen Felder stammen dabei von einem L1-Gast und werden an einen L2-Gast weitergegeben. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um einen Denial of Service Zustand herbeizuführen.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
