Linux Kernel NULL Pointer Dereference Vulnerability in AD7606 ADC Driver

Vulnerability

A vulnerability in the Linux kernel's AD7606 analog-to-digital converter (ADC) driver has been addressed. The issue was a NULL pointer dereference caused by the driver calling the 'sw_mode_config' function without checking if the function pointer was NULL. This oversight occurred because not all buses define this callback, leading to potential crashes.

Impact

Exploitation of this vulnerability could lead to a system crash due to a NULL pointer dereference.
