CVE-2025-35979: Information Disclosure in Intel(R) Processors
CVE-2025-35979 is an information disclosure vulnerability affecting some Intel(R) Processors. It arises from shared microarchitectural predictor state influencing transient execution within VMX non-root (guest) operation. An unprivileged, authenticated local attacker with high attack complexity could potentially expose sensitive data without requiring user interaction. The vulnerability impacts confidentiality but does not affect integrity or availability. No official patch or remediation level has been provided yet, and no known exploits are reported in the wild.
AI Analysis
Technical Summary
This vulnerability involves exposure of sensitive information due to shared microarchitectural predictor state that affects transient execution on certain Intel processors during VMX non-root operation. An attacker with local authenticated access and high complexity attack capabilities may leverage this to disclose confidential data. The CVSS 4.0 base score is 6.8 (medium severity), reflecting local attack vector, high attack complexity, and high confidentiality impact. No vendor advisory or patch information is currently available, and the vulnerability does not impact system integrity or availability.
Potential Impact
The vulnerability may lead to unauthorized disclosure of sensitive information on affected Intel processors when exploited locally by an authenticated user. There is no impact on system integrity or availability. No known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should limit local authenticated access to sensitive systems and monitor for updates from Intel regarding mitigation or patches.
