CVE-2023-37029
Linuxfoundation Magma ≤ 1.8.0
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-2023-37029 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 at the 49th 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-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-2023-37029 is an assertion-based denial-of-service vulnerability affecting Magma versions up to and including 1.8.0, specifically impacting the Mobility Management Entity (MME) component. The flaw triggers a crash when the MME processes an oversized Non-Access Stratum (NAS) packet, as rated at CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and mapped to CWE-617 (Reachable Assertion). This issue was fixed in Magma version 1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486.
An attacker can exploit this vulnerability over the network with low complexity and no privileges required. Exploitation is possible either through a compromised base station or by using an unauthenticated cellphone within range of a base station managed by the vulnerable MME. By sending oversized NAS packets repeatedly, the attacker can cause ongoing crashes of the MME, resulting in a denial of service that disrupts network connectivity for users relying on the affected infrastructure.
Mitigation requires upgrading to Magma v1.9 or later, incorporating the specified fixing commit. Additional details on the vulnerability, including technical analysis, are available in the advisory at https://cellularsecurity.org/ransacked.
