Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in the brcm_avs_is_firmware_loaded() function in the Linux Kernel's brcmstb-avs-cpufreq.c driver, where a lack of proper checks may lead to a NULL pointer dereference. This is caused by a call to the cpufreq_cpu_get() function, which may return NULL and whose output is then stored in the policy value which is referenced later on in the function. This issue may lead to system instability.
