Overview
CVE-2025-0005 is a high-severity vulnerability affecting the AMD XOCL driver. This vulnerability stems from improper input validation, which can be exploited by a local attacker to trigger an integer overflow condition. Successful exploitation can lead to a system crash or denial-of-service (DoS) situation.
This article provides a comprehensive overview of the vulnerability, including technical details, CVSS analysis, potential impact, and recommended mitigation steps.
Technical Details
The vulnerability resides in how the AMD XOCL driver handles specific input parameters. Due to insufficient validation, a malicious local attacker can supply input values that, when processed by the driver, result in an integer overflow. This overflow can corrupt memory, leading to unpredictable behavior, including system crashes or a complete denial of service.
The specifics of the affected code section and vulnerable parameters are detailed in the AMD Security Bulletin. Understanding the exact input and code flow requires further analysis of the patched driver versions.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. CVE-2025-0005 has been assigned the following score:
- CVSS Score: 7.3 (HIGH)
This score indicates a high level of risk, primarily due to the potential for denial of service and the relative ease with which a local attacker can exploit the vulnerability.
Possible Impact
The successful exploitation of CVE-2025-0005 can have significant consequences:
- Denial of Service (DoS): An attacker can crash the affected system, making it unavailable to legitimate users.
- System Instability: The integer overflow can corrupt system memory, leading to unpredictable behavior and system instability.
- Potential for Further Exploitation: While the primary impact is DoS, depending on the specific implementation, the overflow could potentially be leveraged for more severe attacks, though this is less likely given the driver context and the ‘local’ attack vector.
Mitigation and Patch Steps
The primary mitigation for CVE-2025-0005 is to apply the official patch provided by AMD. Follow these steps:
- Identify Affected Systems: Determine which systems are using the affected AMD XOCL driver version.
- Download and Install the Patch: Obtain the appropriate driver update from the AMD support website.
- Verify the Patch: After installation, verify that the updated driver version is installed correctly.
- Monitor Systems: Continuously monitor systems for any signs of unusual behavior.
