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()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/hsr/hsr_netlink.c"],"versions":[{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"9f13023607f1e95bd098cc49052b0c8955d334f9","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"798ccb12810a58a37264685b28ddf990ef49559c","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"9bf45feee630be868ab54e3d0f3d430c07471f0e","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"016b8eaca53bfd57e84ea28b5c9174c89d7679e1","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"25b69f281cebe051a8e4ab19950a939c27ead1bc","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"24b3f1a9982c176d05a523a4bb9314dca0db4488","status":"affected","versionType":"git"},{"version":"f421436a591d34fa5279b54a96ac07d70250cc8d","lessThan":"a762fabd7ef9a6cc07258684138f9c3f078d0326","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/hsr/hsr_netlink.c"],"versions":[{"version":"3.13","status":"affected"},{"version":"0","lessThan":"3.13","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"6.12.111"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.13","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9f13023607f1e95bd098cc49052b0c8955d334f9"},{"url":"https://git.kernel.org/stable/c/798ccb12810a58a37264685b28ddf990ef49559c"},{"url":"https://git.kernel.org/stable/c/9bf45feee630be868ab54e3d0f3d430c07471f0e"},{"url":"https://git.kernel.org/stable/c/016b8eaca53bfd57e84ea28b5c9174c89d7679e1"},{"url":"https://git.kernel.org/stable/c/25b69f281cebe051a8e4ab19950a939c27ead1bc"},{"url":"https://git.kernel.org/stable/c/24b3f1a9982c176d05a523a4bb9314dca0db4488"},{"url":"https://git.kernel.org/stable/c/a762fabd7ef9a6cc07258684138f9c3f078d0326"}],"title":"hsr: broadcast netlink notifications in the device's net namespace","x_generator":{"engine":"bippy-1.2.0"}}}}
