Intel Metrics Discovery API: Integer underflow leads to denial of service
Summary
Intel Metrics Discovery Application Programming Interface software before version 1.16.189 contains an integer underflow (CWE-191) in the Ring 3 user-mode component. A local user with a valid low-privilege account can trigger it with low complexity and no user interaction, causing a denial of service of the affected process. Confidentiality and integrity are not affected, and the attack is not possible remotely.
Affected
- Intel Metrics Discovery Application Programming Interface software before version 1.16.189
- Affected CVE: CVE-2026-63018 (CVSS 4.0: 4.8, Medium)
Fixed in
- Update to version 1.16.189 or later (Intel recommendation)
- Download location: https://github.com/intel/metrics-discovery/tags
Workaround
- Unknown. Intel documents no workaround beyond updating.
- Limit local access to trusted users on shared systems until the update is applied.
Exploitation
- Not listed in CISA KEV. EPSS below 1%.
- No evidence of exploitation in the wild found.
- No public proof of concept found.
Our recommendation
- Identify machines with Intel GPU driver packages or the Metrics Discovery component and verify the version.
- Update to version 1.16.189 or later with the next regular driver or tooling update.
- Prioritise shared multi-user Intel GPU hosts and terminal servers.
- Priority for typical SME workstations: low.

Original description (NVD)
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.
