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-2023-37024 is a high-severity Reachable Assertion (CWE-617) vulnerability in Linuxfoundation Magma. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 47% of CVEs by exploit likelihood; 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-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2023-37024 is a reachable assertion vulnerability (CWE-617) in the Mobile Management Entity (MME) component of Magma versions up to and including 1.8.0. The flaw allows remote attackers to trigger an assertion failure by sending a Non-Access Stratum (NAS) packet containing an Emergency Number List Information Element. The vulnerability 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) and was published on 2025-01-21.
Any remote attacker with access to send NAS packets can exploit this vulnerability using an unauthenticated cellphone, requiring no privileges, user interaction, or special conditions due to its low attack complexity and network accessibility. Successful exploitation crashes the MME, resulting in a denial-of-service condition that disrupts mobile network management functions without impacting confidentiality or integrity.
The vulnerability is fixed in Magma v1.9 at commit 08472ba98b8321f802e95f5622fa90fec2dea486. Additional details on mitigation are available in the advisory at https://cellularsecurity.org/ransacked.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds reachable assertions during development.
Security engineering principles discourage use of assertions for handling untrusted input.
Validating untrusted inputs structurally prevents attacker data from reaching and triggering assertions.

Runtime monitoring of software can detect assertion-triggered crashes as adverse events.
Vulnerability identification processes can discover and record reachable-assertion flaws before deployment.
Secure SDLC practices directly prevent unsafe assertions from being coded in reachable paths.
