Two vulnerabilities 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.


Two vulnerabilities have been discovered in NVIDIA drivers:

  • 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 (CVE-2012-4225).
  • A buffer overflow error has been discovered in NVIDIA drivers (CVE-2013-0131).

NOTE: Exposure to CVE-2012-4225 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

  # emerge --sync
  # emerge --ask --oneshot --verbose
