However, batadv_v_ogm_send_meshif() may still dispatch OGMs via\nbatadv_v_ogm_queue_on_if() for interfaces that have since lost their\nmesh_iface association. This results in a NULL pointer dereference when\nbatadv_v_ogm_queue_on_if() unconditionally calls netdev_priv() on the\nnow NULL hard_iface->mesh_iface to retrieve the batadv_priv.\n\nIt is necessary to ensure that the batadv_v_ogm_queue_on_if() checks that\nit is using the same mesh_iface for which batadv_v_ogm_send_meshif() was\ncalled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/040fe8eb34624002071dd21de9824dfe668ce65d","https://git.kernel.org/stable/c/1be1e99cbd5b74a69d3f92200ca87cf1bce852db","https://git.kernel.org/stable/c/31dcb9711abd1dcd2080d9fac05c79dd9997d6bf","https://git.kernel.org/stable/c/4ff461af943efb5e74d09942d5ffee7644d1e1fe","https://git.kernel.org/stable/c/70c9f6ab0d8f785087fb74fb85464a9a5288bfdb"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-52913","score":0.00123,"percentile":0.01991,"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).
