Apple Confirms Macs and iOS Devices Affected by ‘Meltdown’ Chip Flaw

Apple Inc. said all Mac computers and iOS devices, like iPhones and iPads, are affected by chip security flaws unearthed this week. But the company stressed there are no known exploits impacting users.

Every electronic device you use on a daily basis including Apple products could be in danger from two major vulnerabilities with dramatic-sounding names: Meltdown and Spectre.

The Cupertino, California-based company said recent software updates for iPads, iPhones, iPod touches, Mac desktops and laptops, and the Apple TV set-top-box mitigate one of the vulnerabilities known as Meltdown. The Apple Watch, which runs a derivative of the iPhone’s operating system is not affected, according to the company.

Despite concern that fixes may slow down devices, Apple said its steps to address the Meltdown issue haven’t dented performance. The company will release an update to its Safari web browser in coming days to defend against another form of the security flaw known as Spectre. These steps could slow the speed of the browser by less than 2.5 percent, Apple said in a statement posted on its website.

Apple shares rose less than 1 percent to $173.56 in early trading Friday in New York.

Intel Corp. on Wednesday confirmed a report stating that its semiconductors contain a vulnerability based around a chip-processing technique called speculative execution. Intel said its chips contain the flaw as well as processors based on ARM Holdings architecture, which is used in iOS devices and Android smartphones.

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 has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown. Apple Watch is not affected by Meltdown. In the coming days, we plan to release mitigations in Safari to help defend against Spectre.

Security experts have said highly regulated sectors of industry, such as government offices and public health institutions. These are most at risk of compromise as a result of the chip security vulnerability.
