Description
drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir).
An out-of-bounds read flaw was found in the DVB USB subsystem of the Linux kernel. There was no boundary check applied to the array in struct technisat_usb2_state state->buf until the 0xff byte is encountered. If the byte is not encountered within the limit, an exposure of kernel data structure occurs. Data confidentiality and system availability are the highest threats with this vulnerability.
