CVE-2026-95332 is an information-disclosure vulnerability in Chrome's WebGPU/Dawn stack, specifically Tint's SPIR-V builtin polyfill handling of the WebGPU subgroupBroadcast operation. On affected GPU configurations with subgroup sizes below 128, an out-of-range constant subgroup ID was insufficiently masked or validated. Rather than yielding an indeterminate value, the generated handling could expose a value held in a GPU register. This could potentially disclose GPU shader contents across origins to JavaScript executing through Chrome's unsandboxed GPU process. The issue does not involve memory corruption.
