This means that the\nRCU pointer has been acquired before rcu_read_lock(), which renders\nrcu_read_lock() ineffective and could lead to a use-after-free.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0dc76205549b4c25705e54345f211b9f66e018a0","https://git.kernel.org/stable/c/21989cb5034c835b212385a2afadf279d8069da0","https://git.kernel.org/stable/c/a4bd1caf591faeae44cb10b6517e7dacb5139bda","https://git.kernel.org/stable/c/dc6d1249ee35c1c76700b4b96281daeb7637bce1","https://git.kernel.org/stable/c/f98b191f78124405294481dea85f8a22a3eb0a59"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2025-68374","score":0.00214,"percentile":0.11683,"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).
