CVE-2017-8924

Published: 12 May 2017

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.

From the Ubuntu security team

It was discovered that an integer underflow existed in the Edgeport USB Serial Converter device driver of the Linux kernel. An attacker with physical access could use this to expose sensitive information (kernel memory).

Priority

Medium
