CVE-2025-2136Network attack vector

Heap corruption via Inspector use-after-free

Published Mar 10, 2025 · Updated Feb 26, 2026

Use-after-free in Inspector in Google Chrome before 134.0.6998.88 allows remote attackers to trigger heap corruption via crafted HTML. Google identifies a freed Inspector object as the memory-safety locus, but the restricted Chromium issue leaves the lifetime error and triggering object undisclosed. The target must render attacker-controlled HTML; public vendor material bounds the result to heap corruption and does not document code execution.
