Local kernel code execution via out-of-bounds write
Published Aug 24, 2022 · Updated Oct 21, 2025
Kernel out-of-bounds write in Apple iOS and iPadOS before 15.6.1 and macOS Monterey before 12.5.1 allows local applications to execute kernel code. Apple identifies the kernel as the locus and says inadequate bounds checking permits an out-of-bounds write, but has not disclosed the affected function or input path. Execution requires a local application and user interaction, and successful exploitation crosses into kernel privileges; active exploitation is cataloged.
