NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-wireless package and not the kernel-uek-modules-wireless package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

usb: image: mdc800: kill download URB on timeout

mdc800_device_read() submits download_urb and waits for completion. If the timeout fires and the device has not responded, the function returns without killing the URB, leaving it active.

A subsequent read() resubmits the same URB while it is still in-flight, triggering the WARN in usb_submit_urb():

"URB submitted while active"

Check the return value of wait_event_timeout() and kill the URB if it indicates timeout, ensuring the URB is complete before its status is inspected or the URB is resubmitted.
