CVE-2026-16419Network attack vector

Sandbox escape via ANGLE out-of-bounds access

Published Jul 21, 2026 · Updated Jul 21, 2026

Out-of-bounds read and write in Chrome's ANGLE on Android before 150.0.7871.182 allows remote attackers to escape its sandbox via crafted HTML. Public bug details remain restricted, so Google has not disclosed the exact ANGLE code path or missing bounds check that permits the out-of-bounds accesses. A victim must open crafted HTML on an affected Android build; successful exploitation crosses Chrome's sandbox and can compromise confidentiality, integrity, and availability.
