What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
