<description>
|
|
<p>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.
|
|
</p>
|
|
|
|
<p>NOTE: Exposure to this vulnerability is reduced in Gentoo due to 660
|
|
permissions being used on the GPU device nodes by default.
