{"id":"CVE-2026-52913","summary":"batman-adv: v: stop OGMv2 on disabled interface","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: v: stop OGMv2 on disabled interface\n\nWhen a batadv_hard_iface is disabled, its mesh_iface pointer is set to\nNULL. 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-\u003emesh_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.","modified":"2026-07-10T03:54:14.630994254Z","published":"2026-06-24T07:14:11.248Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52913.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/040fe8eb34624002071dd21de9824dfe668ce65d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1be1e99cbd5b74a69d3f92200ca87cf1bce852db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/31dcb9711abd1dcd2080d9fac05c79dd9997d6bf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ff461af943efb5e74d09942d5ffee7644d1e1fe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/70c9f6ab0d8f785087fb74fb85464a9a5288bfdb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aad70db50ea3d7dfe30e402b889ff075a293b287"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d7391a2b854a62235539c68e9cbf6fc7910a8e9a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8ce8b8331a1bc44ad4905886a482214d428b253"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52913.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52913"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0da0035942d47766c32843143fb5dba7a29cb48c"},{"fixed":"d7391a2b854a62235539c68e9cbf6fc7910a8e9a"},{"fixed":"70c9f6ab0d8f785087fb74fb85464a9a5288bfdb"},{"fixed":"040fe8eb34624002071dd21de9824dfe668ce65d"},{"fixed":"31dcb9711abd1dcd2080d9fac05c79dd9997d6bf"},{"fixed":"aad70db50ea3d7dfe30e402b889ff075a293b287"},{"fixed":"1be1e99cbd5b74a69d3f92200ca87cf1bce852db"},{"fixed":"4ff461af943efb5e74d09942d5ffee7644d1e1fe"},{"fixed":"f8ce8b8331a1bc44ad4905886a482214d428b253"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52913.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.6.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52913.json"}}],"schema_version":"1.7.5"}
