Nvidia Fixes Exploit and Updates Drivers for Linux


Nvidia was confronted with a problem last week when a famous X hacker reported the existence of a dangerous exploit in its binary driver. The company has issued a statement and a new set of drivers.

Nvidia has acknowledged the problem, a security exploit that uses NVIDIA UNIX device files to map and program registers to redirect the VGA window, and has managed to plug the leak quite fast.

“We are resolving this problem by blocking user-space access to registers that control redirection of the VGA window. Further, NVIDIA is also blocking user-space access to registers that control GPU-internal microcontrollers, which could be used to achieve a similar exploit”, said the company in a short communique.

The older 295 release series will be updated soon, and additionally, a patch to the kernel interface layer of the NVIDIA kernel module is available, which can be used to patch older drivers.
