If the lower device is dormant, that queues the\nnew netdev on lweventlist while it is still uninitialized. If\nregistration fails after that, for example because of an invalid name\nsuch as \"bad/name\", free_netdev() immediately frees the object. A\nlater linkwatch_fire_event() then use-after-frees the list entry.\n\nMove the transfer to after netdev_upper_dev_link(), as macvlan and\nipvlan already do.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/293c56a66510bb7de073a1aba388e38abddff1fb","https://git.kernel.org/stable/c/9ce26201f6dedf3fa02b97da8c67ee6f6c5f7225","https://git.kernel.org/stable/c/b808a9af5fd21f9c68b0d024eda7535b5dce6a4e","https://git.kernel.org/stable/c/ca49763c42c1089d654bf11b037980a9ede3772c","https://git.kernel.org/stable/c/e5c8d7acd31b27057ea42cd405d0b3ece097bc89"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98311","score":0.00135,"percentile":0.02927,"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).
