CVE-2025-30402Network attack vector

Runtime crash via tensor-size integer overflow

Published Jul 11, 2025 · Updated Jul 11, 2025

Heap-buffer overflow in ExecuTorch 0.6.0 and earlier allows context-dependent attackers to crash the runtime through a crafted program file. The calculate_nbytes routine multiplies tensor dimensions and element size without overflow checks, allowing a wrapped allocation size during method loading. A host application must load attacker-controlled method metadata; the published assessment reports confidentiality loss and a runtime crash without data modification.
