A flaw was found in the Linux kernel's MediaTek MT7530 network switch driver. This flaw allows a local user with administrative privileges to cause a Denial of Service (DoS) through a kernel crash. The issue occurs during driver unbinding or module removal on specific hardware variants, where the kernel attempts to disable uninitialized power regulators, triggering a null pointer dereference.
