CVE-2025-9020: 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.
The exploitability of CVE-2025-9020 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).
This vulnerability, CVE-2025-9020, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
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.
Above is the CVSS Sub-score Breakdown for CVE-2025-9020, 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.
Below is the Impact Analysis for CVE-2025-9020, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
