{"id":"AZL-100640","summary":"CVE-2026-89531 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsvcrdma: Reject connection when transport allocation fails\n\nhandle_connect_req() returns without action when\nsvc_rdma_create_xprt() fails to allocate the new transport.\nThe CM core returns 0 for CONNECT_REQUEST events, so it does\nnot destroy the new rdma_cm_id. Each allocation failure under\nmemory pressure leaks one rdma_cm_id, and a remote peer driving\nconnection attempts can amplify this.\n\nReject the connection by returning a non-zero status from the\nCM event handler, which tells the CM core to destroy the\norphaned cm_id.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:35Z","upstream":["CVE-2026-89531"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89531"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-100640.json"}}],"schema_version":"1.9.0"}
