Detailsinfo

A vulnerability was found in Intel Neural Compressor up to 3.5 and classified as problematic. This issue affects an unknown function. The manipulation with an unknown input leads to a protection mechanism vulnerability. Using CWE to declare the problem leads to CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at intel.com. The identification of this vulnerability is CVE-2026-20906 since 01/13/2026. The exploitation is known to be easy. An attack has to be approached locally. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/11/2026).

Upgrading to version 3.6 eliminates this vulnerability.
