Doc Text:
A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service.

Description Mauro Matteo Cascella 2023-07-31 08:43:39 UTC 
The usb_giveback_urb function in the linux kernel has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, and it falls into an endless loop and occupies CPU resources, resulting in a denial of service attack.
