Vulnerability from github – Published: 2025-06-10 18:32 – Updated: 2025-11-21 21:30

Details

Improper register access control in ASP may allow a privileged attacker to perform unauthorized access to ASP’s Crypto Co-Processor (CCP) registers from x86, resulting in potential loss of control of cryptographic key pointer/index, leading to loss of integrity or confidentiality.

Severity

7.9 (High)

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.
