In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]cpufreq/longhaul: handle NULL policy in longhaul_exit[EOL][EOL]longhaul_exit() was calling cpufreq_cpu_get(0) without checking[EOL]for a NULL policy pointer. On some systems, this could lead to a[EOL]NULL dereference and a kernel warning or panic.[EOL][EOL]This patch adds a check using unlikely() and returns early if the[EOL]policy is NULL.[EOL][EOL]Bugzilla: #219962
