CVE-2025-35987
Intel Software Guard Extensions Data Center Attestation Primitives Denial of Service Vulnerability
Description
Omission of security-relevant information for some Intel(R) Software Guard Extensions Data Center Attestation Primitives within Ring 0: Kernel may allow a denial of service. Authorized adversary with a privileged user combined with a high complexity attack may enable data alteration. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (high) and availability (low) impacts.
