{"cve":"CVE-2026-97419","nvd":{"published":"2026-09-24T17:17:19.733","modified":"2026-10-03T11:17:54.000","status":"Received","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nhsr: broadcast netlink notifications in the device's net namespace\n\nThe HSR generic netlink family sets .netnsok = true. HSR devices can\nlive in network namespaces other than init_net.\n\nTwo async notifiers broadcast events with genlmsg_multicast(). They\nare hsr_nl_ringerror() and hsr_nl_nodedown(). That helper delivers\nonly on the default genl socket in init_net. So the events always land\nin init_net. The network namespace of the device does not matter.\n\nThis has two effects. A listener in the device's own namespace never\nsees its own ring error and node down events. A privileged listener in\ninit_net receives events from HSR devices in other namespaces. The\npayload carries the peer node MAC (HSR_A_NODE_ADDR) and the slave port\nifindex (HSR_A_IFINDEX).\n\nSwitch both callers to genlmsg_multicast_netns(). Other families with\n.netnsok = true already do this. Examples are gtp, ovpn, team,\nbatman-adv, netdev-genl, ethtool and handshake.\n\nhsr_nl_ringerror() already has the slave port. It uses\ndev_net(port->dev). hsr_nl_nodedown() takes the namespace from the\nmaster port via hsr_port_get_hsr().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/016b8eaca53bfd57e84ea28b5c9174c89d7679e1","https://git.kernel.org/stable/c/24b3f1a9982c176d05a523a4bb9314dca0db4488","https://git.kernel.org/stable/c/25b69f281cebe051a8e4ab19950a939c27ead1bc","https://git.kernel.org/stable/c/798ccb12810a58a37264685b28ddf990ef49559c","https://git.kernel.org/stable/c/9bf45feee630be868ab54e3d0f3d430c07471f0e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97419","score":0.00173,"percentile":0.06632,"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).
