DESCRIPTION:
Two vulnerabilities have been reported in the NVIDIA CUDA Toolkit
Developer Drivers for Linux, which can be exploited by malicious,
local users to disclose potentially sensitive information.

The vulnerabilities are caused due to the "cudaHostAlloc()" and
"cuMemHostAlloc()" API calls returning uncleared pinned memory, which
can be exploited to disclose potentially sensitive memory contents.

The vulnerabilities are reported in NVIDIA CUDA Toolkit 3.2 Developer
Drivers for Linux version 260.19.26 (64Bit). Other versions may also
be affected.

SOLUTION:
Restrict access to trusted users.

PROVIDED AND/OR DISCOVERED BY:
