A vulnerability was found in PX4 PX4-Autopilot up to 1.15.4. This issue affects the function MavlinkReceiver::handle_message_serial_control of the file src/modules/mavlink/mavlink_receiver.cpp of the component Mavlink Shell Closing Handler. The manipulation of the argument _mavlink_shell leads to use after free. An attack has to be approached locally. The complexity of an attack is rather high. The exploitation is known to be difficult. The identifier of the patch is 4395d4f00c49b888f030f5b43e2a779f1fa78708. It is recommended to apply a patch to fix this issue.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.5, requiring local system access to exploit but requires specific conditions to be met without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited data confidentiality, limited integrity, and limited availability for affected systems.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
