Apple Releases watchOS 7.6.1 With Important Security Updates

Apple today released watchOS 7.6.1 to the public, an update that the company says brings “important security updates.” To that end, we’d suggest installing this update as soon as possible to ensure you are fully protected.

According to Apple, the fix deals with a IOMobileFrameBuffer issue that could allow bad actors to run code with kernel privileges.

Available for: Apple Watch Series 3 and later

Impact: An application may be able to execute arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited.

Description: A memory corruption issue was addressed with improved memory handling.

We’d always suggest that people install later versions of watchOS on their devices whenever a new version is released, but that is doubly the case when you’re dealing with a security issue. Throw in the fact that this security fix is to deal with an issue that could allow code to be run with kernel privileges, and it really is a no brainer. Install the update ASAP to ensure you’re fully covered.

Apple says this update will work on all Apple Watch Series 3 and later devices, although anyone who is running the watchOS 8 beta will have to wait for the fix to be rolled into that release — it’s impossible to downgrade Apple Watch software at this time.
