Overview
CVE-2025-58314 is a medium severity vulnerability affecting a device driver module. The vulnerability stems from improper handling of memory access, potentially allowing an attacker to access invalid memory locations. Successful exploitation of this vulnerability can lead to a compromise of both device availability and confidentiality.
Technical Details
The vulnerability lies within the driver module’s code, specifically in how it manages memory pointers during a certain operation. An attacker could potentially craft a malicious input that triggers the driver to access an out-of-bounds memory address. This invalid memory access can result in a denial-of-service (DoS) condition by crashing the affected device or, in more severe cases, lead to information disclosure by reading sensitive data from memory that should not be accessible. The exact attack vector and vulnerable code section are detailed in the vendor’s advisory.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-58314 is 6.6 (Medium). This score reflects the potential impact on both availability and confidentiality. A successful exploit would require the attacker to have some level of access to the affected device, making remote, unauthenticated exploitation less likely. The CVSS vector string associated with this score provides a more granular view of the vulnerability characteristics.
Possible Impact
The impact of exploiting CVE-2025-58314 includes:
- Denial of Service (DoS): The device or its specific functions may become unavailable due to crashes or unexpected behavior.
- Information Disclosure: Sensitive data residing in memory could be exposed to an attacker. This could include configuration details, cryptographic keys, or user data.
- Potential for Privilege Escalation: Although not explicitly stated, the vulnerability could be chained with other vulnerabilities to achieve higher privileges on the affected system.
Mitigation or Patch Steps
The recommended mitigation strategy is to apply the patch provided by the device vendor as soon as possible.
- Apply the Official Patch: Download and install the security patch provided by the vendor (in this case, referenced in the Huawei bulletin). This is the primary and most effective method of mitigating the vulnerability.
- Monitor Network Traffic: Monitor network traffic for any suspicious activity that might indicate an attempted exploitation of this vulnerability.
- Implement Least Privilege Principle: Ensure that users and processes only have the minimum necessary privileges to perform their tasks, reducing the potential impact of a successful exploit.
