NVIDIA CUDA Toolkit 3.2 cudaHostAlloc information disclosure

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in NVIDIA CUDA Toolkit 3.2. It has been classified as problematic. This affects the function cudaHostAlloc. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

The (1) cudaHostAlloc and (2) cuMemHostAlloc functions in the NVIDIA CUDA Toolkit 3.2 developer drivers for Linux 260.19.26, and possibly other versions, do not initialize pinned memory, which allows local users to read potentially sensitive memory, such as file fragments during read or write operations.

The weakness was released 01/07/2011 by Alex (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2011-0636 since 01/22/2011. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1592 according to MITRE ATT&CK.

The vulnerability is also documented in the databases at X-Force (64710), SecurityFocus (BID 45717†), OSVDB (70420†), Secunia (SA42859†) and SecurityTracker (ID 1024962†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
