CVE-2026-12014 is a high-severity use-after-free vulnerability in the Cast component of Google Chrome affecting versions prior to 149.0.7827.115. The flaw arises from incorrect lifetime management of memory in Cast, creating a condition where freed memory may be accessed again. An attacker on the same local network segment can potentially trigger the vulnerability by sending malicious network traffic, leading to memory corruption and a possible browser sandbox escape.
