Description

The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow.

Techniques & Countermeasures

  • CWE-191•Integer Underflow (Wrap or Wraparound)

    The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.

Affected Systems

  • debian•debian_linux

    8.0 | 9.0

  • linux•linux_kernel

    ≤ 4.10.3
