Published: 07 April 2026
Summary
CVE-2025-52908 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Samsung Exynos 1280 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 5.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the buffer overflow vulnerability by requiring timely application of Samsung's published security patches to the affected Wi-Fi driver.
Implements memory protection mechanisms like ASLR and non-executable memory to prevent arbitrary code execution from buffer overflow exploitation in the Wi-Fi driver.
Requires validation of NL80211 vendor command inputs via ioctl messages to prevent buffer overflows due to incorrect handling.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in Wi-Fi driver enables remote unauthenticated arbitrary code execution (T1203) and kernel-level privilege escalation (T1068).
NVD Description
An issue was discovered in the Wi-Fi driver in Samsung Mobile Processor and Wearable Processor Exynos 980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. Incorrect Handling of the NL80211 vendor command leads to a buffer overflow via…

a certain ioctl message, issue 1 of 2.
Deeper analysisAI
CVE-2025-52908 is a buffer overflow vulnerability (CWE-120) in the Wi-Fi driver of Samsung Mobile Processor and Wearable Processor Exynos 980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. The issue stems from incorrect handling of the NL80211 vendor command, which can be triggered via a certain ioctl message. It is designated as issue 1 of 2 in the affected components and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity.
Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation leads to a buffer overflow, potentially enabling arbitrary code execution with high impacts on confidentiality, integrity, and availability.
