{"id":"AZL-102335","summary":"CVE-2026-90253 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: MGMT: free the mesh send cancel command when it is cancelled\n\nmesh_send_cancel() queues the pending command with a NULL destroy\ncallback, so it is only freed if send_cancel() runs. A cancelled entry is\nleaked, as _hci_cmd_sync_cancel_entry() does not release entry-\u003edata when\nthere is no destroy callback, and hci_cmd_sync_clear() cancels every\npending entry when the controller is unregistered. Nothing else reclaims\nit either: mgmt_pending_new() does not put the command on\nhdev-\u003emgmt_pending.\n\nThe leak also pins the socket reference taken by mgmt_pending_new(), so\nthe mgmt socket is never released.\n\nFree the command from a destroy callback.","modified":"2026-09-18T14:18:02.642847094Z","published":"2026-09-17T17:17:21Z","upstream":["CVE-2026-90253"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90253"}],"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-102335.json"}}],"schema_version":"1.9.0"}
