A vulnerability in the Linux kernel's cpufreq subsystem was resolved by changing the initialization order of a semaphore (policy->rwsem). Previously, the semaphore was initialized after the sysfs directory and attributes were created, allowing sysfs access to reach a policy callback before the semaphore was ready. This could lead to improper synchronization. The fix ensures the semaphore is initialized before the policy kobject is published to sysfs.
