CVE-2026-97904
In the Linux kernel, the following vulnerability has been resolved:

cpufreq: initialize policy rwsem before sysfs publication

cpufreq_policy_alloc() initializes policy->rwsem after
kobject_init_and_add() has created the policy sysfs directory and its
default attributes. A sysfs access can therefore reach a policy callback
before the semaphore has been initialized.

Initialize policy->rwsem before publishing the policy kobject so sysfs
callbacks always see an initialized semaphore.
