iPhones, iPads, and Macs are all affected by the big Google-discovered processor flaw

  • Apple confirmed Thursday its devices are affected by the same processor security flaw Google discovered that became public this week.
  • The company has already issued patches in the latest versions of its MacOS, iOS, and tvOS operating systems that address one of the two potential exploits Google found for the flaw.
  • Apple says the fixes don’t affect the performance of its devices.

All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time,” Apple said in a blog post that represented its first public comment on the processor vulnerability.

Apple tried to calm potential fears about the vulnerability, noting it’s already taken action to protect against it. The latest versions of its mobile, desktop, and Apple TV operating systems — iOS 11.2, macOS 10.13.2, and tvOS 11.2, respectively — all contain fixes meant to mitigate the Meltdown exploit in particular. Apple has already released all of those updates, so if you own any of those devices, you can protect them by making sure your operating system is up-to-date.

Apple Watch isn’t vulnerable to the Meltdown attack, the company said.

Apple hasn’t issued any fixes that would specifically address the Spectre exploit. While that attack is thought to be more difficult to pull off, it’s also harder to guard against, and Apple Watch is as vulnerable to it as the rest of Apple’s product line. However, Apple says it planning to test and release fixes that address the Spectre exploit soon.

Earlier on Thursday, Amazon and Google both reported that they, too, found worries that fixes to the chip vulnerability would affect performance were overblown.
