Apple released surprise software updates for iPhone, iPad and Mac on Wednesday that address two security vulnerabilities that Apple has known to be actively exploited by attackers.
Both vulnerabilities were found in WebKit, the browser engine that powers Safari and other apps, and the kernel, essentially the heart of the operating system. Both faults affect both iOS and iPadOSand macOS Monterey.
Apple said the WebKit bug could be exploited if a vulnerable device accesses or processes “maliciously crafted web content that may lead to execution of arbitrary code”, while the second bug allows a malicious application “to execute arbitrary code with kernel privileges”, which means full access. At the phone. The two faults are believed to be related.
Some successful exploits, such as powerful nation-state spyware, use two or more vulnerabilities in conjunction to break through a device’s protection lawyers. It is not uncommon for attackers to first target a vulnerability in the device’s browser in order to penetrate the larger operating system, granting the attacker broad access to sensitive user data.
Apple has stated that iPhone 6s and later, iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation) and all models iPad Pro are affected.
Apple did not respond to a request for comment.
