Linux Kernel TI ADS1298 IIO ADC Driver NULL Pointer Dereference Vulnerability

A vulnerability in the Linux kernel's IIO ADC subsystem for the TI ADS1298 device has been addressed. The issue was a potential NULL pointer dereference because the function 'ads1298_initdevm_kasprintf()' could return NULL on failure, and this return value was not properly checked in 'ads1298_init()'. The vulnerability has been resolved by adding the necessary NULL check.

Impact

Exploitation of this vulnerability could lead to a NULL pointer dereference, causing a kernel crash or undefined behavior.
