{"id":"CVE-2026-40064","kind":"vulnerability","aliases":["CVE-2026-40064"],"related":[],"title":"Intel oneAPI CLI Tool: input validation flaw allows local denial of service","description":"Improper input validation for some Intel(R) oneAPI CLI Tool software within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an unauthenticated 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 active 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 oneAPI CLI Tool software does not validate input properly, so a local user-level program can crash or disrupt it.
