{"id":"CVE-2026-63018","kind":"vulnerability","aliases":["CVE-2026-63018"],"related":[],"title":"Intel Metrics Discovery API: integer underflow lets local user crash apps","description":"Integer underflow (wrap or wraparound) for some Intel(R) Metrics Discovery Application Programming Interface software before version 1.16.189 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 with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"Some versions of Intel's Metrics Discovery Application Programming Interface contain an integer underflow that an unprivileged local user process can trigger.
