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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/27c9b491bf7604e83b50c3bbfa18a30266ff345f","tags":[]},{"url":"https://git.kernel.org/stable/c/2cee937f779f69b195b37bbec1e888da9bfe9d58","tags":[]},{"url":"https://git.kernel.org/stable/c/3e5d1bf4bd687beb2cb4e32a07af695455925588","tags":[]},{"url":"https://git.kernel.org/stable/c/dc11263cb05ed519758fd135fe08d611bad1f241","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
