Kernel code execution via memory handling
Published Dec 15, 2022 · Updated Apr 21, 2025
A kernel memory-management vulnerability in Apple tvOS, macOS, and watchOS allows remote attackers with root privileges to execute arbitrary code with kernel privileges. The Kernel component used flawed memory handling and checks; Apple has not disclosed the precise operation or input that triggers the flaw. Exploitation requires an app already running with root privileges or arbitrary kernel read/write capability, and Apple reports possible exploitation of pre-iOS 15.7.1 releases.
