  "account": "An untrusted website can freeze a Mac by using the WebGPU technology. When a malicious site triggers an infinite loop in a WebGPU shader, it causes the graphics processing unit to become unresponsive. As a result, the desktop user interface becomes unusable until a restart is forced. This issue affects only Mac computers and is not observed on other operating systems. The malicious code only requires a user to click a link to execute. Although the rest of the system operates normally, the WindowServer becomes unresponsive, leading to a kernel panic and a restart of the computer. Apple has acknowledged the issue, but has indicated that it does not view it as a security concern, as it primarily results in a crash, hang or recoverable data loss.",
