Use-after-free in Google Chrome Video
CVE-2026-6302 is a high-severity use-after-free vulnerability in the Video component of Google Chrome. It affects Chrome versions prior to 147.0.7727.101 and can be triggered by a remote attacker through a crafted HTML page. The available supporting content indicates the flaw is a memory-lifetime error in which an object used by the Video component is freed prematurely and later dereferenced. The described exploitation pattern involves a malicious page causing the vulnerable code path to free an object, followed by heap shaping with JavaScript-controlled allocations so the freed memory is reclaimed with attacker-controlled data before the dangling pointer is used. Successful exploitation results in arbitrary code execution within the Chrome renderer sandbox.
