CVE-2025-54333 is a vulnerability identified in the Neural Processing Unit (NPU) of the Samsung Mobile Processor Exynos 1380, present through July 2025. The flaw is an invalid pointer dereference occurring in the get_vs4l_profiler_node function, which is part of the video streaming and profiling subsystem interacting with the NPU. This invalid pointer dereference corresponds to CWE-763, indicating a use-after-free or similar memory corruption issue that leads to a crash of the affected component. Exploitation of this vulnerability requires no privileges and no user interaction, and it can be triggered remotely over the network, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to availability, causing denial of service (DoS) by crashing the NPU or related system components, potentially leading to device instability or reboot loops. No confidentiality or integrity impacts are reported. No patches or fixes have been published yet, and there are no known exploits in the wild. The vulnerability affects devices using the Exynos 1380 chipset, which is commonly found in certain Samsung mobile devices released around 2023-2025. Given the nature of the flaw, attackers could cause service interruptions or device crashes remotely, impacting user experience and device reliability.

For European organizations, the primary impact of CVE-2025-54333 is the potential for denial of service on mobile devices powered by the Exynos 1380 processor. This could disrupt business operations relying on mobile communications, especially in sectors where mobile device availability is critical, such as emergency services, logistics, and field operations. While the vulnerability does not compromise data confidentiality or integrity, repeated device crashes or instability could lead to productivity losses and increased support costs. Enterprises with Bring Your Own Device (BYOD) policies may face challenges if employees' devices are affected, potentially impacting secure access to corporate resources. Additionally, mobile network operators and service providers in Europe could see increased support demands or reputational damage if large numbers of devices are affected. The lack of known exploits reduces immediate risk, but the ease of exploitation and network accessibility mean the threat could escalate if weaponized. Overall, the impact is moderate but relevant for organizations with significant Samsung device usage.

1. Monitor Samsung's official security advisories and promptly apply any firmware or software updates addressing this vulnerability once released. 2. Implement network-level protections such as firewall rules and intrusion detection systems to limit exposure of vulnerable devices to untrusted networks, especially blocking unnecessary inbound traffic to mobile devices. 3. Employ mobile device management (MDM) solutions to enforce security policies, control device configurations, and facilitate rapid patch deployment across organizational devices. 4. Educate users about the importance of installing updates and avoiding suspicious network environments that could be exploited to trigger the vulnerability. 5. For critical operations, consider deploying fallback or redundant communication methods to mitigate potential service disruptions caused by device crashes. 6. Collaborate with mobile network operators to receive timely threat intelligence and coordinate response efforts if exploitation attempts are detected. 7. Conduct regular security assessments and penetration testing focused on mobile device infrastructure to identify and remediate related vulnerabilities.
