Published: 08/11/2026 (08/11/2026, 16:25:27 UTC)
Source: CVE Database V5
Product: Intel(R) Processors

Description

Improper access control for some Intel(R) Processors within Ring 3: User Applications may allow an escalation of privilege. Simple hardware adversary with an authenticated 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 requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Technical Analysis

This vulnerability in Intel(R) Processors arises from improper access control in Ring 3 user applications, which may allow an escalation of privilege. Exploitation requires a local attacker with authenticated user privileges and special internal knowledge, combined with a high complexity attack. The vulnerability can impact system confidentiality and integrity but does not affect availability. There is no indication of active exploitation in the wild or available patches at this time.

Potential Impact

The vulnerability can lead to unauthorized escalation of privilege, impacting the confidentiality and integrity of the affected system. Availability is not impacted. The attack requires local access with authenticated user privileges and special internal knowledge, making exploitation complex.
