Linux Kernel Clock Management NULL Pointer Dereference Vulnerability

A vulnerability in the Linux kernel's clock management for Qualcomm GCC SM6350 has been addressed. The issue arose because certain clock configurations (clk_rcg2) lacked a defined parent_map, leading to a NULL pointer dereference when the clock rate was being set. This flaw was traced back to two specific clocks that were missing the parent_map property, causing a potential crash when the system attempted to adjust their frequencies.

Impact

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