Description

This security bulletin contains information about 1 security vulnerability.


1) Resource management errors (CVE-ID: CVE-2010-1083)

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

The processcompl_compat function in drivers/usb/core/devio.c in Linux kernel 2.6.x through 2.6.32, and possibly other versions, does not clear the transfer buffer before returning to userspace when a USB command fails, which might make it easier for physically proximate attackers to obtain sensitive information (kernel memory).
