Impact: Low
Public: 2010-02-17
Bugzilla: 566624: CVE-2010-1083 kernel: information leak via userspace USB interface
IAVA: 2011-A-0147

Details

The MITRE CVE dictionary describes this issue as:

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).
