Description
A flaw was found in the Linux kernel's mdc800 USB image driver. When the driver attempts to read data from a USB device, a timeout can occur, leaving a USB Request Block (URB) in an active state. If a subsequent read operation is initiated, the driver may attempt to resubmit this already active URB. This improper handling of URBs can lead to system instability or a denial of service.
