A vulnerability in NVIDIA drivers may allow a local attacker to gain escalated privileges.
|Package||x11-drivers/nvidia-drivers on all architectures|
|Affected versions||< 295.40|
|Unaffected versions||>= 295.40|
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.
There is no known workaround at this time.
All NVIDIA driver users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-drivers/nvidia-drivers-295.40"
