Das BSI ist als Anbieter für die eigenen, zur Nutzung bereitgestellten Inhalte nach den allgemeinen Gesetzen verantwortlich. Nutzerinnen und Nutzer sind jedoch dafür verantwortlich, die Verwendung und/oder die Umsetzung der mit den Inhalten bereitgestellten Informationen sorgfältig im Einzelfall zu prüfen.
Produktbeschreibung: Der Kernel stellt den Kern des Linux Betriebssystems dar.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um beliebigen Programmcode auszuführen, einen Denial of Service zu verursachen oder Informationen offenzulegen.
Betroffene Betriebssysteme: - Linux
Es existiert eine Schwachstelle im Linux Kernel. Die Implementierung des DCCP-Protokolls handhabt die Wiederverwendung von Sockets nicht ordnungsgemäß, was dazu führt, dass die DCCP-CCID-Struktur des Linux-Kernels nachträglich verwendet werden kann. Ein lokaler Angreifer kann diese Schwachstelle ausnutzen, um einen Denial of Service zu verursachen oder möglicherweise beliebigen Code auszuführen.

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.
