A sysfs access can therefore reach a policy callback\nbefore the semaphore has been initialized.\n\nInitialize policy->rwsem before publishing the policy kobject so sysfs\ncallbacks always see an initialized semaphore.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
