CVE-2026-10988Network attack vector

Sandbox escape via Views use-after-free

Published Jun 4, 2026 · Updated Jun 4, 2026

Use after free in Google Chrome's Views component before 149.0.7827.53 allows remote attackers to escape the renderer sandbox through crafted HTML. Public Google records do not disclose the affected Views object or the lifetime operation that leaves freed memory accessible. Exploitation requires an already-compromised renderer process, and the published consequence is crossing the renderer sandbox boundary.
