Impact	Critical CVSS 9.8 reflects unauthenticated network-exploitable buffer overflow in widely-deployed Samsung mobile processors. Low EPSS (0.01%) suggests minimal observed exploitation activity despite severity. Blast radius spans multiple Exynos variants across Samsung devices. Practical impact depends on Wi-Fi driver exposure and vendor patching speed; prioritize firmware updates for affected devices.
Exploit ScenarioDerived	Attacker sends crafted NL80211 vendor ioctl message over network to trigger buffer overflow in Wi-Fi driver. No authentication required. Successful exploitation enables code execution with device privileges. No public exploit identified at time of analysis.

AnalysisAIv1 – Apr 07, 2026

Buffer overflow in Samsung Exynos Wi-Fi driver (980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000) allows unauthenticated remote code execution via malformed NL80211 vendor command ioctl message. Incorrect handling of vendor-specific wireless configuration commands enables network-based memory corruption. CVSS 9.8 critical severity reflects network attack vector requiring no authentication or user interaction. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.01%).

RemediationAI

Vendor-released patch: Apply Samsung Semiconductor security updates per advisory at https://semiconductor.samsung.com/support/quality-support/product-security-updates/cve-2025-52908/. Device manufacturers using affected Exynos chipsets must integrate firmware updates into Android/Tizen security patches and push OTA updates to end-user devices. Check device manufacturer security bulletins for model-specific patch availability timelines. No workaround exists for kernel-level driver vulnerability; disable Wi-Fi on affected devices until patched if exposure to untrusted networks is unavoidable. Monitor Samsung's product security portal for chipset-specific firmware versions and integration guidance for OEMs.

Technical ContextAI · show details

Root cause is CWE-120 buffer overflow in Exynos chipset Wi-Fi driver's NL80211 vendor command parser. Improper bounds checking when processing ioctl messages to nl80211 vendor-specific interface allows attacker-controlled data to overflow allocated buffer. Network Layer 80211 (nl80211) cfg80211 kernel interface mishandles vendor command extension parsing, enabling memory corruption through crafted wireless management frames.

DescriptionCVE.org

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.

Executive ViewAI

Why It Matters

CVE-2025-52908 is a critical remote code execution vulnerability in Samsung Exynos Wi-Fi drivers (affecting models 980, 850, 1280, 1330, 1380, 1480, 1580, W920, W930, W1000) that allows unauthenticated attackers to execute arbitrary code over the network without user interaction. Any organization deploying Samsung Exynos-based devices-including mobile phones, tablets, and IoT equipment-faces risk of complete device compromise and potential lateral movement into corporate networks.

Business Impact: Severe

Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: disable Wi-Fi on non-essential Exynos devices; restrict affected devices to isolated, monitored networks; implement strict wireless access controls and monitor for anomalous connection attempts; segment affected devices from systems handling sensitive data; enable enhanced logging and behavioral monitoring for suspicious activity on impacted devices.

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
