CVE-2025-49495 is a security vulnerability identified in the WiFi driver component of Samsung's Exynos mobile processors, specifically models 1380, 1480, 2400, and 1580. The flaw stems from improper handling of NL80211 vendor-specific commands, which are part of the Linux wireless subsystem used to communicate with WiFi hardware. This mishandling results in a buffer overflow condition, where data exceeding the allocated buffer size overwrites adjacent memory. Buffer overflows can lead to unpredictable behavior including memory corruption, crashes, or arbitrary code execution. Since the vulnerability exists in the WiFi driver, it can potentially be triggered remotely by sending crafted WiFi management frames or vendor commands to a vulnerable device. The affected processors are widely used in Samsung smartphones, which are prevalent in consumer and enterprise environments. No CVSS score has been assigned yet, and no patches or known exploits have been reported as of the publication date. The vulnerability's exploitation could allow attackers to compromise device integrity, gain elevated privileges, or disrupt device availability. Given the nature of the flaw, exploitation might not require user interaction or authentication, increasing the risk profile. The vulnerability highlights the importance of secure driver development and vendor command validation in wireless components.

For European organizations, the impact of CVE-2025-49495 could be significant, especially those relying on Samsung smartphones with affected Exynos processors for secure communications, mobile workforce operations, or critical business applications. Successful exploitation could lead to unauthorized access to sensitive data, disruption of mobile device availability, or persistent compromise of user devices. This could cascade into broader organizational risks including data breaches, loss of operational continuity, and reputational damage. The vulnerability could also be leveraged in targeted attacks against high-value individuals or sectors such as finance, government, and telecommunications. Since mobile devices are often used as multi-factor authentication tokens or for remote access, compromise could undermine broader network security. The absence of patches increases exposure time, and the lack of known exploits suggests the window for proactive mitigation is still open. However, the potential for remote exploitation without user interaction elevates the threat level for organizations with mobile-dependent workflows.

Organizations should implement the following specific mitigations: 1) Inventory and identify all Samsung devices using Exynos 1380, 1480, 2400, or 1580 processors within their environment. 2) Restrict WiFi connectivity to trusted networks and disable WiFi when not in use to reduce exposure to malicious crafted NL80211 commands. 3) Employ network segmentation and monitoring to detect anomalous WiFi management frames or vendor command traffic indicative of exploitation attempts. 4) Engage with Samsung and mobile device management (MDM) vendors to obtain timely security updates and patches once available. 5) Educate users on the risks of connecting to untrusted WiFi networks and encourage the use of VPNs for secure communications. 6) Prepare incident response plans specific to mobile device compromise scenarios. 7) Consider deploying endpoint detection and response (EDR) solutions capable of monitoring device driver behavior and memory anomalies. 8) Collaborate with telecom providers to monitor for suspicious wireless activity targeting mobile devices. These measures go beyond generic advice by focusing on device-specific controls and proactive detection strategies.
