Vulnerability details

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the drivers/media/usb/dvb-usb/technisat-usb2.c USB driver in Linux kernel. A local user can use a specially crafted USB device to trigger out-of-bounds read error during data transfer and read contents of memory on the system.
