The Linux Foundation Magma version 1.8.0 and earlier has been identified with a critical buffer overflow vulnerability. This vulnerability allows attackers to cause a Denial of Service (DoS) through crafted NAS packets. With a CVSS score of 7.5, it is classified as a high-severity vulnerability, indicating significant risk to organizations utilizing this software.
The vulnerability specifically lies within the decode_access_point_name_ie function in the source file located at /3gpp/3gpp_24.008_sm_ies.c. Given its nature, this vulnerability can be exploited easily, as it does not require any privileges or user interaction, which heightens its risk profile.
Organizations using the affected versions of Magma are urged to prioritize patching immediately to mitigate the risk of potential exploitation. The fix is available in version 1.9, which addresses this vulnerability.
As of now, there are no known exploits associated with this vulnerability in public databases, but organizations should remain vigilant due to its potential impact.
Vulnerability Details
The official description of the vulnerability states that it allows attackers to induce a Denial of Service via crafted NAS packets. The vulnerability is classified under CWE-120, which pertains to buffer errors that can lead to unexpected behaviors or system crashes.
The CVSS score of 7.5 indicates a high severity, characterized by a network attack vector, low attack complexity, no privileges required, and no user interaction necessary. The availability impact is rated as high, meaning successful exploitation could result in significant outages.
The vulnerability was published on January 21, 2025, and has been modified since its initial disclosure. The affected product is the Linux Foundation Magma, specifically all versions up to and including 1.8.0.
Technical Analysis
Root cause analysis points to a failure in input validation within the decode_access_point_name_ie function, leading to buffer overflow conditions. The attack vector is network-based, allowing remote attackers to trigger this condition without local access.
The attack complexity is low; it does not require any special conditions to be met prior to exploitation. The required privileges are none, and user interaction is also not needed. This vulnerability has a high impact on availability due to the nature of the Denial of Service it can induce.
In terms of impact, confidentiality and integrity are rated as having no impact, while availability is significantly affected. This means that if exploited, the system could become completely unresponsive, leading to downtime and operational disruptions.
Risk & Impact Analysis
Risk to organizations includes potential service outages and loss of productivity due to the Denial of Service, which may affect not only the vulnerable system but also any dependent services or applications. The blast radius is significant; since the vulnerability is network-exploitable, it can be targeted from anywhere without restrictions.
Given the high CVSS score, organizations must assess their exposure to this vulnerability quickly. The urgency of the situation is compounded by the fact that no known exploits are confirmed, but the low attack complexity means attackers may seek to exploit it rapidly once awareness spreads.
Organizations should take proactive measures to schedule remediation within their patch management cycles promptly. This vulnerability should be treated with high priority due to its potential impact on availability.

Affected Versions
The affected versions of the Linux Foundation Magma software include all versions up to and including 1.8.0. Organizations should upgrade to version 1.9 or later to mitigate this vulnerability.
Mitigation & Remediation
Organizations must apply the patch available in version 1.9 to remediate this vulnerability. If immediate upgrading is not feasible, consider implementing network segmentation to limit exposure to the vulnerable systems.
Configuration hardening and deploying firewalls to monitor and control traffic to affected systems can also mitigate potential exploitation attempts. Continuous monitoring for abnormal behavior on networks is recommended to detect any attempts to exploit this vulnerability.
Penetration testing can help identify weaknesses in the system before attackers can exploit them.
Detection Guidance
To detect potential exploitation attempts, organizations should monitor logs for unusual network traffic patterns, especially those indicating malformed packets being sent to the affected systems. Behavioral anomalies, such as unexpected system crashes or downtime, should also be investigated.
Setting up network signatures to alert on abnormal traffic patterns associated with the NAS packet structure can help in early detection of potential attacks.
AppSecure Threat Intelligence Insight
This vulnerability underscores the importance of maintaining up-to-date software versions to mitigate risks associated with buffer overflow vulnerabilities. The potential for Denial of Service attacks highlights the need for organizations to implement robust monitoring and incident response strategies.
Security teams should focus on proactive measures to identify and remediate vulnerabilities before they can be exploited. Continuous security assessments, such as application security assessments, can provide insights into potential weaknesses in their systems.
Additionally, organizations should consider leveraging red teaming services to simulate attacks and enhance their defensive posture.
In conclusion, organizations must remain vigilant against vulnerabilities like CVE-2024-24416 by prioritizing timely updates and employing comprehensive security strategies.
