The company said in an online support document that it has recently added security protections to MacOS and iOS created to prevent one series of attacks, known as Meltdown, and is working to update Safari to prevent against another type of attack, dubbed Spectre.
Intel said its chips, which power Macs and devices from other manufacturers, contain the flaw as well as processors based on ARM Holdings architecture, which is used in iOS devices and Android smartphones.
Apple stressed that there were no known instances of hackers taking advantage of the flaw to date.
The security vulnerabilities apply to all modern computer processors and affect almost all computers and smartphones, leaving tech companies scrambling to find a fix.
According to a statement by the company, the vulnerabilities dubbed Meltdown and Spectre could allow hackers to get access to sensitive information on the users' computers and other devices.More news: Khloé Kardashian Reveals When She'll Announce Her Baby's Sex & Talks Pregnancy Cravings!

"All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time ..." Apple also added that since it would take a malicious app to set off Meltdown or Spectre, it recommends that iOS and Mac users install apps from a trusted source only, such as the App Store.
Apple also announced that it will be releasing patches for Spectre in the form of an update to web browser Safari in a few days.
It said that it had already issued "mitigations" against the risks of Meltdown, which affects Intel chips, so customers who download the latest software updates for their devices should be safe. However, the Cupertino tech giant has said that its users don't need to worry as updates are already available to fix the issues. It said that Apple Watch is not affected.
Apple hasn't issued any fixes that would specifically address the Spectre exploit. In the coming days we plan to release mitigations in Safari to help defend against Spectre. "We continue to develop and test further mitigations for these issues and will release them in upcoming updates of iOS, macOS, tvOS, and watchOS", reads the statement.
