AN ADVISORY from a security researcher called Gregory Shikhman points out that Nvidia drivers have a rather gaping hole when installed under Gentoo Linux.
The X-11 drivers, provided to make the green team's graphics boards work under the popular Linux distro, install - by default - with a bad set of file permissions in the standard /dev/nvidia* directory.
The file permissions mean that a hacker could alter the drivers and send arbitary code to the board itself, resulting in a software compromise or even damage to the actual Nvidia hardware, should a hacker choose to jack up your clock frequencies on the sly.
