1 vulnerability in this advisory, including CVE-2024-42861.

CVE-2024-42861

Es besteht eine Schwachstelle in IEEE 802.1 AS in der Implementierung linuxptp v.4.2. Dieser Fehler besteht aufgrund der unsachgemäßen Behandlung von Pdelay_Req-Nachrichten. Wenn ein Anschluss zwei Pdelay_Req-Nachrichten mit unterschiedlichen ClockIDs empfängt, wird die Zeitsynchronisationsfunktion deaktiviert. Ein entfernter, anonymer Angreifer aus dem selben Ethernet Netzwerk kann diese Schwachstelle ausnutzen, um einen Denial-of-Service-Zustand zu erzeugen, der die Uhrensynchronisationsfunktionalität unterbricht.

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.
