A vulnerability in NVIDIA drivers may allow a local attacker to gain escalated privileges.

2.  Impact Information


The NVIDIA drivers provide X11 and GLX support for NVIDIA graphic boards.


A vulnerability has been found in the way NVIDIA drivers handle read/write access to GPU device nodes, allowing access to arbitrary system memory locations.

NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660 permissions being used on the GPU device nodes by default.


A local attacker could gain escalated privileges.

3.  Resolution Information


There is no known workaround at this time.


All NVIDIA driver users should upgrade to the latest version:

Code Listing 3.1: Resolution
