CVE-2025-47868 Vulnerability Summary

CVE-2025-47868: Out-of-bounds Write resulting in possible Heap-based Buffer Overflow vulnerability was discovered in tools/bdf-converter font conversion utility that is part of Apache NuttX RTOS repository. This standalone program is optional and neither part of NuttX RTOS nor Applications runtime, but active bdf-converter users may be affected when this tool is exposed to external provided user data data (i.e. publicly available automation). This issue affects Apache NuttX: from 6.9 before 12.9.0. Users are recommended to upgrade to version 12.9.0, which fixes the issue.

Assessing the Risk of CVE-2025-47868

Access Complexity Graph

The exploitability of CVE-2025-47868 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2025-47868

With low attack complexity and no required privileges, CVE-2025-47868 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-47868, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2025-47868, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

Confidentiality: High
Exploiting CVE-2025-47868 can result in unauthorized access to sensitive data, severely compromising data privacy.
Integrity: High
CVE-2025-47868 could allow unauthorized modifications to data, potentially affecting system reliability and trust.
Availability: High
CVE-2025-47868 can disrupt system operations, potentially causing complete denial of service (DoS).
