Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: Init completion before kobject_init_and_add()
In cpufreq_policy_alloc(), it will call uninitialed completion in cpufreq_sysfs_release() when kobject_init_and_add() fails. And that will cause a crash such as the following page fault in complete:
