Denial of service via heap buffer overflow
Published Oct 13, 2026 · Updated Oct 13, 2026
Heap buffer overflow in NVIDIA Warp allows attackers to cause denial of service via unspecified vectors requiring user interaction. The retrieved disclosure does not identify the affected function, triggering input, or incorrect buffer operation, and the referenced vendor bulletin was inaccessible. The published assessment places exploitation locally; the disclosure does not distinguish a crash from a hang or establish remote reachability.
