A vulnerability was found in technisatusb2getir in drivers/media/usb/dvb-usb/technisat-usb2.c in DVB USB subsystem, there was an out-of-bounds read for an array in struct technisatusb2state state->buf with no boundary check applied until 0xff byte is encountered, if it is not found with in the limits it goes beyond the array size, this exposes kernel data structure which should not happen.

Other sources

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).

— Ubuntu

Linux Kernel could allow a physical attacker to obtain sensitive information, caused by an out-of-bounds read flaw in technisat-usb2.c. By using a specially-crafted USB device, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condition on the system.
