Depending on when you last updated Windows 10, the hotfix might have one of a variety of different names, but you're looking for Security Update for Windows (KB4056892) if you have the Fall Creators Update already installed. If not, click on Update history or View installed update history to see if it was already installed. To make sure your PC is protected, go to Settings > Update & security to check and see if the security fix is waiting in your update queue.

If you're running Windows 10, it should automatically download and install - but it might depend on your PC's settings. Microsoft says it released a security update Wednesday to help mitigate the issue.

If not, you can probably go to Settings > General > Software Update to download the latest version.Īpple says the patches don't measurably affect performance, and it'll continue to develop more mitigations for future updates. To check, go to Settings > General > About and look for Version to verify you're on 11.2 or later. 2, included a number of mitigations, and Apple's promising to develop more protections in future updates. Apple says that version, released on Dec. If you've already installed the latest iOS version 11.2 on your iPhone or iPad, you should already be protected from some of the vulnerabilities that researchers discovered as of last month.

watchOS is unaffected by Spectre.We'll update this story as manufacturers commit to updates. We continue to develop and test further mitigations within the operating system for the Spectre techniques. On January 8th Apple released updates for Safari on macOS and iOS to mitigate such timing-based techniques. Testing performed when the Safari mitigations were released indicated that the mitigations had no measurable impact on the Speedometer and ARES-6 tests and an impact of less than 2.5% on the JetStream benchmark.

Spectre is a name covering multiple different exploitation techniques, including-at the time of this writing-CVE-2017-5753 or "bounds check bypass," and CVE-2017-5715 or "branch target injection," and CVE-2018-3639 or “speculative bounds bypass.” These techniques potentially make items in kernel memory available to user processes by taking advantage of a delay in the time it may take the CPU to check the validity of a memory access call.Īnalysis of these techniques revealed that while they are extremely difficult to exploit, even by an app running locally on a Mac or iOS device, they can be potentially exploited in JavaScript running in a web browser. We continue to develop and test further mitigations for these issues. Apple Watch is not affected by either Meltdown or Spectre. 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.Īpple has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown. Security updates for macOS Sierra and OS X El Capitan also include mitigations for Meltdown. To help defend against Spectre, Apple has released mitigations in iOS 11.2.2, the macOS High Sierra 10.13.2 Supplemental Update, and Safari 11.0.2 for macOS Sierra and OS X El Capitan. All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at the time of this writing. These issues apply to all modern processors and affect nearly all computing devices and operating systems. Security researchers have recently uncovered security issues known by two names, Meltdown and Spectre.
