This list entry\nitself was one of the references which need to be dropped at the same time\nvia batadv_claim_put().\n\nBut the batadv_claim_put() must not be done before the last access to the\nclaim object in this function. Otherwise the claim might be freed already\nby the batadv_claim_release() function before the list entry was dropped.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/00155f336a5e8b1006d2ca9ae7ad8fc4a44bb401","https://git.kernel.org/stable/c/0cc9847c64cb6e61118bc78c9187c8209a7197fa","https://git.kernel.org/stable/c/1d4b241482d9025c537afb3c7c8419c72c0e0c82","https://git.kernel.org/stable/c/368449e467d5f1e2c2e987bf2bd57000ba75e10b","https://git.kernel.org/stable/c/4ae1709a314060a196981b344610d023ea841e57"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-46212","score":0.00274,"percentile":0.19787,"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).
