{"id":"AZL-84207","summary":"CVE-2026-31676 affecting package kernel for versions less than 6.6.137.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: only handle RESPONSE during service challenge\n\nOnly process RESPONSE packets while the service connection is still in\nRXRPC_CONN_SERVICE_CHALLENGING. Check that state under state_lock before\nrunning response verification and security initialization, then use a local\nsecured flag to decide whether to queue the secured-connection work after\nthe state transition. This keeps duplicate or late RESPONSE packets from\nre-running the setup path and removes the unlocked post-transition state\ntest.","modified":"2026-08-28T17:48:03.361151032Z","published":"2026-04-25T09:16:01Z","upstream":["CVE-2026-31676"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31676"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.137.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-84207.json"}}],"schema_version":"1.9.0"}
