Operationally, ranked at the 37.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Timely flaw remediation requires patching the specific buffer overflow in Magma's decode_access_point_name_ie function to the fixed version v1.9.
Information input validation checks crafted NAS packets for validity before decoding, directly preventing the buffer overflow.
Memory protection mechanisms like ASLR and stack canaries mitigate buffer overflow exploitation attempts in the vulnerable function.
NVD Description
The Linux Foundation Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) was discovered to contain a buffer overflow in the decode_access_point_name_ie function at /3gpp/3gpp_24.008_sm_ies.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.
Deeper analysisAI
CVE-2024-24416 is a buffer overflow vulnerability (CWE-120) affecting the Linux Foundation's Magma project in versions up to and including 1.8.0. The flaw resides in the decode_access_point_name_ie function within the file /3gpp/3gpp_24.008_sm_ies.c. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity primarily due to its potential for availability disruption. The issue was fixed in Magma v1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486.
Remote attackers with network access can exploit this vulnerability by sending a specially crafted Non-Access Stratum (NAS) packet to a vulnerable Magma instance. No authentication, privileges, or user interaction are required, and the attack has low complexity. Successful exploitation triggers the buffer overflow, leading to a Denial of Service (DoS) condition, such as application crashes or service unavailability, without impacting confidentiality or integrity.
Mitigation involves upgrading to Magma v1.9 or later, which includes the fixing commit. Additional details are available in the advisory at https://cellularsecurity.org/ransacked, published on 2025-01-21.
