CVE-2026-13030Network attack vector

Process-memory disclosure via uninitialized GPU data

Published Jun 24, 2026 · Updated Jun 24, 2026

Uninitialized memory use in Google Chrome on Android before 149.0.7827.197 allows remote attackers to read process memory via crafted HTML. The public record identifies the GPU component but does not disclose which code path consumes uninitialized storage or how the crafted page exposes it. A user must open the crafted page on an affected Android device; the documented consequence is process-memory disclosure, with no integrity or availability impact.
