In the official announcement of the new version, Google developers provide an overview of four of the security vulnerabilities that have been fixed. These are a use-after-free vulnerability in the Angle component, which acts as a WebGL engine and could allow the execution of malicious code, as well as two other vulnerabilities of the same name in the Dawn and WebCodecs components.
Additionally, a type confusion in WebAssembly has been fixed, which is also a potential security risk. The updated versions have the numbers:
- 123.0.6312.80 for Android
- 123.0.6312.86 for Linux
- 123.0.6312.86/.87 for macOS and Windows
