CVE-2026-95332Network attack vector

Cross-origin memory disclosure via unchecked subgroupBroadcast ID

Published Sep 29, 2026 · Updated Sep 29, 2026

Uninitialized memory use in Google Chrome on Android before 154.0.8037.57 allows remote attackers to read GPU-process memory via crafted HTML. Tint's SPIR-V writer fails to guard an out-of-range subgroupBroadcast ID, allowing an uninitialized GPU register value to reach JavaScript. The victim must load WebGPU content on affected Android graphics hardware; the public issue reports no memory corruption or attacker control over the register contents.
