CVE-2026-40704
Description
A flaw was found in neural-compressor due to a failure in its protection mechanism within user applications. A local attacker could exploit this issue with passive interaction from a privileged user to achieve privilege escalation. Successful exploitation allows an unprivileged attacker to gain elevated privileges on the system.
Statement
A protection mechanism failure in Intel Neural Compressor allows a local, unprivileged user with passive user interaction to escalate privileges within user-space applications, resulting in high confidentiality, integrity, and availability impacts.
Mitigation
Restrict interactive shell access and execution of untrusted model quantization or evaluation workflows within Intel Gaudi vLLM containers to trusted, least-privileged service accounts, and run inference pods with standard OpenShift security context constraints (SCCs) that drop unnecessary capabilities and prevent privilege escalation.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
