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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/27c9b491bf7604e83b50c3bbfa18a30266ff345f","https://git.kernel.org/stable/c/2cee937f779f69b195b37bbec1e888da9bfe9d58","https://git.kernel.org/stable/c/3e5d1bf4bd687beb2cb4e32a07af695455925588","https://git.kernel.org/stable/c/82a54923700da5de83ce2b26c0b43f6b5005c8f1","https://git.kernel.org/stable/c/b14987a0f73777644099f47f01aba3b0f9dc6c27"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97904","score":0.00216,"percentile":0.11945,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
