CVE-2024-24417
Memory Safety in 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-2024-24417 is a high-severity Out-of-bounds Read (CWE-125) 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 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 SI-10 (Information Input Validation) — 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-2024-24417 is a buffer overflow vulnerability affecting the Linux Foundation's Magma project in versions up to and including 1.8.0. The flaw exists in the decode_protocol_configuration_options function within the file /3gpp/3gpp_24.008_sm_ies.c. It 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) and maps to CWE-125 (Out-of-bounds Read) and CWE-120 (Buffer Copy without Checking Size of Input).
The vulnerability can be exploited remotely by unauthenticated attackers with network access, requiring low complexity and no user interaction. By crafting and transmitting a malicious NAS packet, an attacker can trigger the buffer overflow, resulting in a Denial of Service (DoS) that crashes the affected component and disrupts service availability.
Mitigation is available in Magma version 1.9 through commit 08472ba98b8321f802e95f5622fa90fec2dea486. Security practitioners should update to this fixed version or apply the patch. Further details on the advisory are provided at https://cellularsecurity.org/ransacked.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.
Input validation directly enforces size checks before buffer copies.
Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.
Process isolation confines the effects of an out-of-bounds read to the compromised process.
Memory protection limits the impact of an overflow once it occurs.
