Description
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()
The cpufreq_cpu_put() call in update_qos_request() takes place too early
because the latter subsequently calls freq_qos_update_request() that
indirectly accesses the policy object in question through the QoS request
object passed to it.
Fortunately, update_qos_request() is called under intel_pstate_driver_lock,
so this issue does not matter for changing…
