Apple Issues Critical 0-Day Patch for Mac, iPhone, and iPad

On July 27, 2021, Apple released a crucial security update for iOS, iPadOS, and macOS to fix a zero-day vulnerability that may have already been exploited. This marks the thirteenth such vulnerability Apple has addressed this year. The update, which follows the recent launch of iOS 14.7, iPadOS 14.7, and macOS Big Sur 11.5, resolves a memory corruption issue (CVE-2021-30807) in the IOMobileFrameBuffer, a kernel extension responsible for managing the screen framebuffer. This flaw could allow malicious actors to execute arbitrary code with kernel privileges. Apple stated that it has improved memory handling to mitigate this risk and acknowledged reports of potential exploitation. As is standard, specific details about the vulnerability have not been released to prevent further attacks. An anonymous researcher is credited with discovering and reporting the issue.
