Linux Kernel NULL Pointer Dereference Vulnerability in VCHIQ Core

A vulnerability in the Linux kernel's VCHIQ core has been addressed, which involved a NULL pointer dereference. The issue arose because the function 'find_service_by_handle' returned NULL when given an invalid handle. This vulnerability could be exploited by not properly handling the NULL result, leading to a dereference of a NULL pointer.

Impact

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