Apple on Monday rolled out an urgent security update for iOS, iPadOS, and macOS to address a zero-day flaw that it said may have been actively exploited, making it the thirteenth such vulnerability Apple has patched since the start of this year.
The updates, which arrive less than a week after the company released iOS 14.7, iPadOS 14.7, and macOS Big Sur 11.5 to the public, fixes a memory corruption issue (CVE-2021-30807) in the IOMobileFrameBuffer component, a kernel extension for managing the screen framebuffer, that could be abused to execute arbitrary code with kernel privileges.
