{"id":"CVE-2026-41214","kind":"vulnerability","aliases":["CVE-2026-41214"],"related":[],"title":"Intel Neural Compressor: improper input validation allows local denial of service","description":"Improper input validation for some Intel(R) Neural Compressor software before version 3.8 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"Some Intel Neural Compressor software before version 3.8 does not validate input properly, so a local user-level process can cause a denial of service.
