CVE-2024-6246

Kernel code execution via unchecked heap copy

Published Nov 22, 2024 · Updated Dec 4, 2024

Heap-based buffer overflow in Wyze Cam v3 firmware 4.36.11.7071 allows network-adjacent attackers to execute kernel code. The Realtek Wi-Fi kernel module copies user-supplied data into a heap buffer without validating its length, allowing the copy to overrun the allocation. Exploitation requires no authentication but does require network-adjacent access, and successful attacks execute with kernel privileges on the camera.
