Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
In the Linux kernel, the following vulnerability has been resolved: usb: cdc-wdm: close race between read and workqueue wdm_read() cannot race with itself. However, in service_outstanding_interrupt() it can race with the workqueue, which can be triggered by error handling. Hence we need to make sure that the WDM_RESPONDING flag is not just only set but tested.
