CVE-2025-35979: Information Disclosure in Intel(R) Processors

0
Medium
VulnerabilityCVE-2025-35979cvecve-2025-35979
Published: Tue May 12 2026 (05/12/2026, 16:35:09 UTC)
Source: CVE Database V5
Product: Intel(R) Processors

Description

Exposure of sensitive information caused by shared microarchitectural predictor state that influences transient execution for some Intel(R) Processors within VMX non-root (guest) operation may allow an information disclosure. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.

Technical Analysis

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 exploit this to disclose data. The CVSS 4.0 score is 6.8 (medium severity), reflecting local attack vector, high attack complexity, and high confidentiality impact. There is no indication of integrity or availability impact. No vendor remediation or patch information is provided at this time.

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 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, users should follow Intel's security advisories and consider limiting access to trusted users only, as exploitation requires authenticated local access and high attack complexity.
