Published: 08/11/2026 (08/11/2026, 16:27:18 UTC)
Source: CVE Database V5
Product: Intel(R) Neural Compressor software

Description

Protection mechanism failure for some Intel(R) Neural Compressor software before version v3.6 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Technical Analysis

This vulnerability in Intel(R) Neural Compressor software before version 3.6 is due to a failure in protection mechanisms within Ring 3 user applications. An attacker with local access, possessing unprivileged software combined with a privileged user context, may exploit this flaw to escalate privileges. The attack complexity is low and requires only passive user interaction, without special internal knowledge. The vulnerability affects confidentiality, integrity, and availability at the vulnerable system level but does not propagate to broader system impacts. No known exploits are reported in the wild, and no official fix or patch has been disclosed as of the publication date.

Potential Impact

The vulnerability allows escalation of privilege, potentially compromising the confidentiality, integrity, and availability of the affected Intel(R) Neural Compressor software environment at a high level. However, it does not result in further impacts beyond the vulnerable system context. The attack requires local access and a privileged user context, limiting remote exploitation possibilities.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should limit local access to trusted users and monitor for any unusual privilege escalations. No official remediation or temporary fix is currently documented.
