CVE-2025-35973: Escalation of Privilege in Intel(R) Processors
Improper handling of values for some Intel(R) Processors within Ring 0: Kernel, Hypervisor and Bare Metal OS may allow an escalation of privilege. Authorized adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and require no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.
AI Analysis
Technical Summary
This vulnerability in Intel(R) Processors arises from improper handling of certain values within Ring 0 components such as the Kernel, Hypervisor, and Bare Metal OS. An authorized adversary with privileged user access and high complexity attack capabilities, combined with special internal knowledge, may exploit this flaw locally without user interaction to escalate privileges. The initial impact on confidentiality and integrity is low, but it may lead to higher confidentiality and integrity impacts later. The vulnerability does not affect system availability. There is no vendor advisory or patch information available at this time.
Potential Impact
The vulnerability allows a local privileged user to escalate privileges under conditions requiring high attack complexity and special internal knowledge. Initial impacts on confidentiality and integrity are low, but subsequent impacts on system confidentiality and integrity can be high. Availability is not affected. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation recommendations have been provided by the vendor at this time.
