Detailsinfo

A vulnerability has been found in Intel Neural Compressor and classified as problematic. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Protection mechanism failure for some Intel Neural Compressor software before version master 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.

It is possible to read the advisory at intel.com. This vulnerability is known as CVE-2026-40704 since 04/18/2026. The exploitation appears to be easy. Attacking locally is a requirement.
