Apple has released a minor update to your Apple Watch. WatchOS 7.3.2 fixes a serious vulnerability in the smartwatch that allows malicious code to run via Safari – and that’s actually all the update does.
This is a memory bug in WebKit which is the rendering engine for the Safari browser. Through it, specially prepared websites can run malicious code on your devices, which of course is not desirable.
