CVE-2026-11052Network attack vector

Windows sandbox escape via GPU type confusion

Published Jun 4, 2026 · Updated Jun 4, 2026

Type confusion in Google Chrome's GPU component before 149.0.7827.53 allows remote attackers with renderer control to escape the Windows sandbox. Google identifies the GPU type confusion, but restricted bug details leave the specific object-type mismatch and unsafe operation undisclosed. Exploitation requires a crafted HTML page and prior renderer-process compromise; success crosses the Windows browser sandbox boundary.
