Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-24423 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Linuxfoundation Magma. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked at the 47th 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 map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

CVE-2024-24423 is a buffer overflow vulnerability (CWE-787) in the Linux Foundation's Magma project, affecting versions up to and including 1.8.0. The flaw resides in the decode_esm_message_container function located at /nas/ies/EsmMessageContainer.cpp. It was published on 2025-01-21 and carries 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 vulnerability can be exploited remotely over the network by unauthenticated attackers with low complexity and no user interaction required. By sending a specially crafted Non-Access Stratum (NAS) packet to a vulnerable Magma instance, attackers can trigger the buffer overflow, leading to a Denial of Service (DoS) condition that crashes the affected component.
Mitigation involves upgrading to Magma v1.9 or applying the fixing commit 08472ba98b8321f802e95f5622fa90fec2dea486. Additional details are available in the advisory at https://cellularsecurity.org/ransacked.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.
Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.
Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.
Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.
Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.
Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.
