{"id":"CVE-2026-44627","kind":"vulnerability","aliases":["CVE-2026-44627"],"related":[],"title":"Intel oneDNN: integer overflow lets a local user crash applications","description":"Integer overflow to buffer overflow for some Intel(R) oneAPI Deep Neural Network Library (oneDNN) software before version v2026.0.0 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 present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","summary":"Some versions of Intel's oneAPI Deep Neural Network Library (oneDNN) before v2026.0.0 contain an integer overflow that leads to a buffer overflow.
