Description

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).

Linux kernel: through 2.6.32; 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, 2.6.5 (+332)
