{"id":"AZL-106443","summary":"CVE-2026-98311 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: virt_wifi: don't transfer operstate before register\n\nvirt_wifi_newlink() calls netif_stacked_transfer_operstate() before\nregister_netdevice(). If the lower device is dormant, that queues the\nnew netdev on lweventlist while it is still uninitialized. If\nregistration fails after that, for example because of an invalid name\nsuch as \"bad/name\", free_netdev() immediately frees the object. A\nlater linkwatch_fire_event() then use-after-frees the list entry.\n\nMove the transfer to after netdev_upper_dev_link(), as macvlan and\nipvlan already do.","modified":"2026-10-08T05:35:32Z","published":"2026-10-06T09:18:22Z","upstream":["CVE-2026-98311"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98311"}],"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-106443.json"}}],"schema_version":"1.9.0"}
