Apple backports CoreGraphics zero-day patches to older iPhones

Apple has backported security patches to older iPhones and iPads, addressing a zero-day vulnerability in the CoreGraphics framework. The flaw was originally patched last month for newer devices. The vulnerability was reportedly exploited in 'extremely sophisticated' targeted attacks against iOS devices. By backporting the fix, Apple aims to protect users on older hardware who cannot upgrade to the latest iOS versions. This highlights the ongoing risk of targeted zero-day exploitation against Apple mobile devices and the importance of patch coverage across legacy device ecosystems.
