Vigil@nce - Linux kernel: information disclosure via USB proc_connectinfo

May 2016 by Vigil@nce

This bulletin was written by Vigil@nce : https://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

A local attacker can read a memory fragment of USB
proc_connectinfo() of the Linux kernel, in order to obtain
sensitive information.

 Impacted products: Fedora, Linux.
 Severity: 1/4.
 Creation date: 04/05/2016.

DESCRIPTION OF THE VULNERABILITY

The Linux kernel implements usbfs, which uses the
usbdevfs_connectinfo structure.

However, the proc_connectinfo() function of the
drivers/usb/core/devio.c file does not initialize a memory area of
3 bytes before returning it to the user.

A local attacker can therefore read a memory fragment of USB
proc_connectinfo() of the Linux kernel, in order to obtain
sensitive information.
