Doc Text:
A buffer overflow due to a singed-unsigned comparsion was found in hidp_process_report() in the net/bluetooth/hidp/core.c in the Linux kernel. The buffer length is an unsigned int but gets cast to a signed int which in certain conditions can lead to a system panic and a denial-of-service.
