CVE-2023-37285

Kernel code execution via out-of-bounds read

Published Jul 28, 2023 · Updated Feb 13, 2025

Out-of-bounds read in Apple operating-system kernels allows local users running a crafted app to execute code with kernel privileges. Apple identifies the locus only as Kernel and states that affected builds fail to enforce bounds before a read; no narrower code path is public. The attacker must first run an app on the device, after which successful exploitation grants kernel-level code execution.
