CVE-2026-13788 is a critical use-after-free vulnerability in the Fullscreen component of Google Chrome on Android. The flaw affects Chrome on Android versions prior to 150.0.7871.47. A remote attacker can trigger the vulnerability by causing the target to load a crafted HTML page, leading to memory corruption in Fullscreen handling. As a use-after-free condition, the bug arises when previously freed memory is accessed again, creating the possibility of controlled heap corruption and subsequent code execution.
