Overview
CVE-2025-0003 describes a high-severity Use-After-Free vulnerability discovered in Xilinx Runtime. This flaw stems from inadequate lock protection, potentially allowing a local attacker to trigger a Use-After-Free condition. Successful exploitation could lead to a loss of confidentiality or system availability.
Technical Details
The vulnerability lies within the Xilinx Runtime (XRT). Insufficient locking mechanisms around shared resources allow for a race condition to occur. A local attacker with sufficient privileges can potentially manipulate the timing of operations, leading to a scenario where memory is freed while still being referenced. Subsequently, the attacker can then attempt to access or manipulate the freed memory, causing a Use-After-Free condition.
This issue affects the integrity of the Xilinx Runtime environment and any applications that rely on it.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of security vulnerabilities. For CVE-2025-0003, the CVSS score is 7.3, indicating a HIGH severity.
This score reflects the potential for significant impact on affected systems, as successful exploitation could compromise confidentiality and/or availability. While requiring local access, the relatively high CVSS score highlights the criticality of addressing this vulnerability promptly.
Possible Impact
A successful exploitation of CVE-2025-0003 could have the following impacts:
- Loss of Confidentiality: An attacker might be able to access sensitive information stored in the memory that was prematurely freed.
- Loss of Availability: The vulnerability could lead to system crashes or denial-of-service (DoS) conditions, disrupting normal operations.
- Potential for Further Exploitation: Exploiting this Use-After-Free condition could be a stepping stone for further exploitation, potentially leading to arbitrary code execution (depending on the specific context and system configuration).
Mitigation and Patch Steps
The recommended mitigation is to apply the patch or upgrade to the version of Xilinx Runtime that addresses this vulnerability. AMD has released a security bulletin with details on affected versions and available fixes.
Specifically, refer to the AMD security bulletin for detailed instructions on obtaining and applying the necessary updates. It is crucial to apply these updates as soon as possible to minimize the risk of exploitation.
General recommendations include:
- Stay informed about security advisories from Xilinx/AMD.
- Implement a robust patch management process.
- Minimize local user privileges where possible to reduce the attack surface.
