Apple confirmed on Thursday that all Mac and iOS devices are affected by the Meltdown and Spectre CPU flaws that have roiled the computing industry for the past 24 hours, resulting in a race to patch operating systems and cloud computing infrastructure at the highest levels.
“‘All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time,” the company writes in a blog post. “Since exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device, we recommend downloading software only from trusted sources such as the App Store.”
Apple was one of the last remaining holdouts to speak up about Meltdown and Spectre, although it was already widely believed Apple devices were affected due to the company’s use of components from chip manufactures like Intel and and ARM. Apple says that it has already mitigated some of the potential negative consequences of Meltdown, which is the Intel-specific exploit, with patches to iOS (11.2), macOS (10.13.2), and tvOS (11.2).
The company says it plans to issue patches for Safari to better help the browser defend against Spectre, which is far more widespread because it is an exploit of the kernel memory processes inherent to modern chip architecture across the board. Apple Watch devices, which have used Intel chips in the past, are not affected by Meltdown in any way, the company confirms.
