The net\ncore therefore leaves dev->tstats NULL for PFCP devices.\n\nCreating a PFCP rtnetlink device can immediately ask the new netdev for\nstats while building the RTM_NEWLINK notification.  That reaches\ndev_get_tstats64() and dereferences the NULL dev->tstats pointer.\n\nSet pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so\nthe net core allocates the storage expected by dev_get_tstats64().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/24041543da8cd84eb5d8ae738c534372fff54820","https://git.kernel.org/stable/c/51a1d9836acc76a1bd16170b2f4b35f11036593f","https://git.kernel.org/stable/c/56b4ad500fd1282ef04db3c4beae5b54ab093a53","https://git.kernel.org/stable/c/67e4b283de36d9eebf95acdea5d6674b6ef4b2f4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74286","score":0.00168,"percentile":0.06075,"date":"2026-10-31"},"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).
