  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ncppc_cpufreq: Fix possible null pointer dereference\n\ncppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from\ndifferent places with various parameters. So cpufreq_cpu_get() can return\nnull as 'policy' in some circumstances.\nFix this bug by adding null return check.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.",
