CVE-2025-10585 is a high-severity type confusion vulnerability in the V8 JavaScript and WebAssembly engine used by Google Chrome. In affected Chrome versions prior to 140.0.7339.185 on Linux and prior to 140.0.7339.185/.186 on Windows and macOS, a remote attacker can trigger incorrect interpretation of object types through crafted web content, leading to heap corruption within the browser process. The flaw is reachable by convincing a user to load a specially crafted HTML page. Google reported that exploitation exists in the wild, and multiple reports characterize the issue as a zero-day used in targeted attacks.
