CVE-2026-7361Network attack vector

Heap corruption via iOS use-after-free

Published Apr 28, 2026 · Updated Apr 28, 2026

Use-after-free in Google Chrome before 147.0.7727.138 allows remote attackers to corrupt heap memory through a crafted HTML page. The iOS-specific component accesses an object after its storage has been freed, but Google has not disclosed the affected function, object type, or lifetime error. Exploitation requires a user to load attacker-controlled HTML, and the published record does not establish code execution outside the browser.
