  "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.",
