## Technical details

The vulnerability exists in the ioctl handler of the Exynos NPU driver, where improper validation of user-supplied input allows an out-of-bounds write. The attack requires local code execution (ioctl calls from user space), and successful exploitation results in denial of service through memory corruption.
