CVE-2026-40065 · Severity: info · Published 2026-11-10

Intel Neural Compressor is a software tool that optimizes AI models for performance. A flaw in input validation allows unprivileged users to escalate privileges when a privileged user interacts with the application, potentially compromising system confidentiality, integrity, and availability. An attacker with local access could gain elevated permissions on the system.

## How to fix

- Fixed in 3.7

## Technical details

Improper input validation in Intel Neural Compressor before v3.7 allows privilege escalation via Ring 3 user applications. The vulnerability requires local access with a privileged user present and passive user interaction, affecting system confidentiality, integrity, and availability. Attack complexity is low with high-privilege prerequisites.

## Affected products

- Intel Neural Compressor before 3.7
