CVE-2026-118306 is a memory corruption vulnerability residing in the FileSystem component of Google Chrome. The flaw affects Google Chrome versions prior to 156.0.8078.73. It is triggered when a user interacts with a specially crafted HTML page, allowing a remote attacker to exploit the underlying memory corruption. If successfully exploited, the vulnerability allows a remote attacker to potentially execute arbitrary code outside of the browser's sandbox environment. The exploit can be initiated over a network without requiring any special privileges, though it does depend on user interaction to be executed. Google has addressed this issue in the 156.0.8078.73 update.
