CVE-2025-54332 is a software vulnerability identified in the Neural Processing Unit (NPU) of Samsung's Exynos mobile processors, affecting versions up to July 2025. The flaw is a NULL pointer dereference occurring in the npu_vertex_profileoff function, specifically involving the profiler.node pointer. When this pointer is NULL and the function attempts to dereference it, the system may experience a crash or denial of service condition due to improper error handling. The NPU is responsible for accelerating AI-related tasks on mobile devices, and instability here can affect device performance and reliability. Although no exploits have been reported in the wild, the vulnerability could be triggered by malicious or malformed inputs that cause the profiler.node to be NULL during profiling operations. The absence of a CVSS score indicates that the vulnerability is newly disclosed and pending further assessment. The vulnerability does not appear to allow privilege escalation or code execution directly but can disrupt device availability. Samsung mobile devices using affected Exynos processors are the primary impacted systems. The lack of patch links suggests that a fix is either not yet released or not publicly available at the time of disclosure. The vulnerability requires either local access or an application with sufficient privileges to invoke the vulnerable function, limiting remote exploitation potential. However, given the widespread use of Samsung devices in Europe, the vulnerability could impact enterprise mobile device fleets and consumer devices, potentially causing service interruptions or degraded user experience.

For European organizations, the primary impact of CVE-2025-54332 is on device availability and stability. Enterprises relying on Samsung mobile devices with Exynos processors for business operations, secure communications, or mobile workforce productivity may experience unexpected device crashes or denials of service. This could disrupt critical workflows, especially in sectors like finance, healthcare, and government where mobile device reliability is essential. Consumer devices could also be affected, leading to broader reputational damage for organizations providing mobile services or support. While the vulnerability does not directly compromise confidentiality or integrity, the denial of service could indirectly affect operational continuity. The lack of remote exploitability reduces the risk of widespread attacks but does not eliminate targeted local attacks or malware leveraging this flaw. Additionally, mobile network operators and service providers in Europe may face increased support demands or service degradation if large numbers of devices are affected. The impact is thus moderate but significant in environments with high Samsung device penetration and critical mobile usage.

1. Monitor Samsung’s official security advisories and promptly apply any patches or firmware updates addressing this vulnerability once released. 2. Restrict access to device debugging and profiling interfaces that could invoke the vulnerable npu_vertex_profileoff function, limiting exposure to untrusted applications. 3. Employ mobile device management (MDM) solutions to enforce security policies, control application installations, and monitor device health for signs of instability or crashes. 4. Educate users to avoid installing untrusted or suspicious applications that might trigger the vulnerability. 5. For enterprise environments, consider temporarily limiting the use of affected Samsung devices for critical operations until patches are available. 6. Collaborate with Samsung support channels to obtain early access to fixes or workarounds. 7. Implement anomaly detection on mobile devices to identify abnormal profiling or AI processing behaviors that could indicate exploitation attempts. 8. Maintain regular backups and incident response plans to quickly recover from potential device outages caused by this vulnerability.
