Summary

CVE-2024-52924 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Samsung Exynos 9820 Firmware. 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 32th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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-2024-52924 is a stack-based buffer overflow vulnerability (CWE-121) discovered in the NRMM component of Samsung Mobile Processor, Wearable Processor, and Modem Exynos 9820, 9825, 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 9110, W920, W930, W1000, Modem 5123, Modem 5300, and Modem 5400. The flaw arises from a lack of boundary checks during the decoding of Registration Accept messages, potentially leading to out-of-bounds writes on the stack. 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 was published on 2025-03-06.

The vulnerability can be exploited by remote attackers over the network with low attack complexity, requiring no authentication privileges or user interaction. Exploitation triggers out-of-bounds stack writes, resulting in high-impact denial-of-service conditions through availability disruption, such as process crashes, while confidentiality and integrity remain unaffected.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can discover stack-buffer overflows before deployment.

Input validation directly stops untrusted data from exceeding stack buffer bounds.

Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.

Secure-engineering principles include bounds-checked coding and safe buffer handling that avoid introducing the flaw.
