Published: 21 January 2025
Description
The Linux Foundation Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) was discovered to contain a buffer overflow in the decode_traffic_flow_template_packet_filter function at /3gpp/3gpp_24.008_sm_ies.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.
Security Summary
CVE-2024-24419 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_traffic_flow_template_packet_filter function within the file /3gpp/3gpp_24.008_sm_ies.c. It enables attackers to trigger a Denial of Service (DoS) through a crafted NAS (Non-Access Stratum) packet 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). The issue was addressed in Magma v1.9 via commit 08472ba98b8321f802e95f5622fa90fec2dea486.
The vulnerability is exploitable remotely over the network with low attack complexity, requiring no authentication, privileges, or user interaction. An unauthenticated attacker can send a specially crafted NAS packet to the affected Magma instance, causing the buffer overflow and resulting in a DoS that severely impacts service availability without affecting confidentiality or integrity.
According to available advisories, mitigation requires updating to Magma v1.9 or applying the specified fixing commit. Further details on the vulnerability and remediation are provided at https://cellularsecurity.org/ransacked.
