MediumCVSS 5.4Exploitation Probability (EPSS)
Low risk5th percentile - higher than 5% of all known CVEs
Summary
Protection mechanism failure in Intel(R) LLM Library for PyTorch may allow privilege escalation. An attacker with a privileged user and a low complexity attack can exploit this locally, requiring passive user interaction. The impact on confidentiality, integrity, and availability is high.
Risk Assessment
Risk of privilege escalation in PyTorch with LLM library environment, potentially leading to unauthorized access to models and data.
Recommendation
Apply available updates or patches for Intel(R) LLM Library for PyTorch to remediate the vulnerability.
Original NVD description (English source)
Protection mechanism failure for some Intel(R) LLM Library for PyTorch within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
