Apple has released iOS 16.5.1, bringing fixes for two serious security flaws already being used in real-life iPhone attacks.
iOS 16.5.1 fixes an issue in the Kernel that could allow an attacker to execute code with Kernel privileges.
“Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.7,” the company said.
The second issue fixed in iOS 16.5.1 is a flaw in WebKit, the engine that underpins Apple’s Safari browser, which could enable an attacker to execute code via malicious web content.
Apple said it is “aware of a report that this issue may have been actively exploited.”
iOS 16.5.1 also fixes an issue that prevents charging with the Lightning to USB 3 Camera Adaptor.
It is unclear at the time of publishing why this upgrade was not released as a Rapid Security Response Update, opposed to a point upgrade. Needless to say due to the severity of these vulnerabilities, it is extremely important you update to iOS 16.5.1 as soon as you can.
