EIP-2026-102157

This PoC exploits a use-after-free (UaF) vulnerability in the iOS kernel's persona management code by racing persona allocation and deallocation threads, leading to an extra call to persona_put and potential privilege escalation. The exploit targets a race condition in kpersona_alloc_syscall where an invalid userspace pointer causes a copyout failure, allowing an attacker to manipulate kernel memory.
