{"id":"AZL-93788","summary":"CVE-2026-64408 affecting package kernel for versions less than 6.6.145.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: bnep: pin L2CAP connection during netdev registration\n\nbnep_add_connection() reads the L2CAP connection without holding the\nchannel lock, then passes its HCI device to register_netdev(). Controller\nteardown can clear and release that connection concurrently, leaving the\nnetwork device registration path to dereference a freed parent device.\n\nTake a reference to the L2CAP connection while holding the channel lock.\nRetain it until register_netdev() has taken the parent device reference.","modified":"2026-08-28T17:48:13.117169233Z","published":"2026-07-25T10:17:24Z","upstream":["CVE-2026-64408"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64408"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.145.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-93788.json"}}],"schema_version":"1.9.0"}
