CVE-2025-0007: Xilinx Runtime – A Path to Kernel Privilege Escalation

Overview

CVE-2025-0007 is a medium-severity vulnerability found within the Xilinx Run Time (XRT) framework. This vulnerability stems from insufficient validation of input, which could allow a local attacker to escalate privileges from user space to kernel space. Successfully exploiting this flaw can compromise the confidentiality, integrity, and availability of the affected system.

This vulnerability was published on 2025-11-24T21:16:02.023 and has a CVSS score of 5.7.

Technical Details

The specific technical details of the insufficient validation within the Xilinx Run Time framework are not publicly available beyond the general description provided. However, based on the description, the vulnerability likely resides in how XRT handles data or commands received from user-space applications. The inadequate validation process allows a malicious user to craft specific inputs that bypass security checks, enabling them to execute code with kernel-level privileges. This could involve issues with pointer arithmetic, buffer overflows, or unchecked permissions during data transfer between user and kernel space.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) score for CVE-2025-0007 is 5.7, which is considered a MEDIUM severity vulnerability. A breakdown of the CVSS metrics can be inferred as follows (note: this is an educated guess based on the description and score):

• Attack Vector (AV): Local (L) – An attacker needs local access to the system.
• Attack Complexity (AC): Low (L) – The attack is relatively easy to perform.
• Privileges Required (PR): Low (L) – An attacker requires only basic user privileges.
• User Interaction (UI): None (N) – No user interaction is required to exploit the vulnerability.
• Scope (S): Changed (C) – Exploiting the vulnerability changes the security scope (user to kernel).
• Confidentiality (C): Low (L) – Limited access to sensitive information.
• Integrity (I): Low (L) – Limited modification of data.
• Availability (A): Low (L) – Limited disruption of service.

Possible Impact

The exploitation of CVE-2025-0007 can have significant consequences:

• Privilege Escalation: A local attacker can gain kernel-level privileges, allowing them to bypass security restrictions.
• Data Theft: With kernel access, an attacker can access sensitive data, leading to confidentiality breaches.
• System Compromise: An attacker can modify system files or install malicious software, compromising the integrity of the system.
• Denial of Service: An attacker can cause system crashes or instability, leading to a denial of service.

Mitigation and Patch Steps

The primary mitigation for CVE-2025-0007 is to apply the patch or upgrade to the version of the Xilinx Run Time (XRT) framework specified in the AMD security bulletin. Follow these steps:

1. Identify Affected Systems: Determine which systems are using the Xilinx Run Time framework.
2. Review AMD Security Bulletin: Consult AMD-SB-8014 for detailed information and affected versions.
3. Apply the Patch or Upgrade: Download and install the recommended patch or upgrade to the specified XRT version.
4. Verify the Fix: After applying the patch or upgrade, verify that the vulnerability has been successfully addressed.
5. Monitor Systems: Continuously monitor systems for any signs of suspicious activity.
