Summary

CVE-2024-24418 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Linuxfoundation Magma. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 45th 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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2024-24418 is a buffer overflow vulnerability (CWE-120) in the Linux Foundation's Magma project, affecting versions up to and including 1.8.0. The flaw resides in the decode_pdn_address function located at /nas/ies/PdnAddress.cpp. It was fixed in Magma v1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486. The vulnerability 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 remote denial-of-service.

Unauthenticated attackers with network access can exploit this vulnerability by sending a specially crafted NAS (Non-Access Stratum) packet to the affected Magma instance. Successful exploitation triggers the buffer overflow, leading to a denial-of-service condition, such as application crashes or service disruptions, without requiring user interaction or privileges.

Mitigation involves upgrading to Magma v1.9 or later, which includes the fixing commit 08472ba98b8321f802e95f5622fa90fec2dea486. Additional details are available in the advisory at https://cellularsecurity.org/ransacked.
