{"id":"AZL-103916","summary":"CVE-2026-97419 affecting package kernel 6.6.157.1-1","details":"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-\u003edev). hsr_nl_nodedown() takes the namespace from the\nmaster port via hsr_port_get_hsr().","modified":"2026-09-25T14:16:08.411167378Z","published":"2026-09-24T17:17:19Z","upstream":["CVE-2026-97419"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97419"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103916.json"}}],"schema_version":"1.9.0"}
