A cancelled entry is\nleaked, as _hci_cmd_sync_cancel_entry() does not release entry->data 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->mgmt_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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/05438d338a875a9daa08ca3f6a35b4480cf13de4","tags":[]},{"url":"https://git.kernel.org/stable/c/3c742feda8fcabf741a17bcf668b63c8f606f9c5","tags":[]},{"url":"https://git.kernel.org/stable/c/416fabca9b7237b76aa9cafcf8c497b8ac00d88c","tags":[]},{"url":"https://git.kernel.org/stable/c/88e30d036d777b00aed42bd35000de23ff40910c","tags":[]},{"url":"https://git.kernel.org/stable/c/b609341ee56967d9a45845ff26f79336d2114b55","tags":[]},{"url":"https://git.kernel.org/stable/c/fa46d428c014e7b72a18634679815670418e67dc","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
