Why should you install watchOS 7.6.1 on your Apple Watch

watchOS 7.6 arrived on July 19 and unlocked the ECG feature in thirty more countries, including Bulgaria, Ukraine, Estonia and Slovenia, Jersey, Monaco, the Vatican, and the Dominican Republic. Now, users in these countries have a way to alert each other about an irregular heartbeat.

Now, a little over a week later, a new update has arrived. Apple claims that watchOS 7.6.1 “provides important security updates and is recommended for all users.” This latest update, arriving on July 28, fixes an IOMobileFrameBuffer flaw that could have led to the execution of an arbitrary code.

The arrival of the Emergency Security Update comes a few days after iOS 14.7.1 and Big Sur 11.5.1, which also fixed the same IOMobileFrameBuffer security flaw.

The Mobile Frame Buffer is a frame that controls how the device’s memory handles the screen. The same framework was used five years ago for a jailbreak. At that time, Team Pangu was exploiting the loophole to jailbreak systems up to iOS 9.9.9. Apple closed that gap soon after.

Apple explicitly writes that the current bug has already been actively exploited, so updating to iOS 14.7.1, macOS 11.5.1, and now watchOS 7.6.1 is recommended for everyone.
