{"id":"AZL-88976","summary":"CVE-2026-46214 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nvsock/virtio: fix accept queue count leak on transport mismatch\n\nvirtio_transport_recv_listen() calls sk_acceptq_added() before\nvsock_assign_transport(). If vsock_assign_transport() fails or\nselects a different transport, the error path returns without\ncalling sk_acceptq_removed(), permanently incrementing\nsk_ack_backlog.\n\nAfter approximately backlog+1 such failures, sk_acceptq_is_full()\nreturns true, causing the listener to reject all new connections.\n\nFix by moving sk_acceptq_added() to after the transport validation,\nmatching the pattern used by vmci_transport and hyperv_transport.","modified":"2026-08-28T17:46:38.912289898Z","published":"2026-05-28T10:16:37Z","upstream":["CVE-2026-46214"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46214"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88976.json"}}],"schema_version":"1.9.0"}
