CVE-2015-5053
HighSummary
The host memory mapping path feature in the NVIDIA GPU graphics driver R346 before version 346.87 and R352 before version 352.41 for Linux and R352 before version 352.46 for GRID vGPU and vSGA does not properly restrict access to third-party device IO memory. This allows attackers to gain privileges, cause a denial of service (resource consumption), or possibly have unspecified other impact via unknown vectors related to the follow_pfn kernel-mode API call.
Risk Assessment
Organizations may be exposed to unauthorized access to system resources, potentially leading to serious security issues, including denial of service and privilege escalation.
Recommendation
It is recommended to update NVIDIA GPU drivers to the latest versions to mitigate this vulnerability and to monitor systems for unauthorized activities.
