A VPU driver is specialized software that enables the operating system and applications to communicate with the Video Processing Unit (VPU) in a device. The VPU is a dedicated hardware component designed to handle complex video processing tasks such as decoding, encoding, and rendering video streams efficiently. The driver translates high-level commands into instructions the VPU can execute, ensuring optimal performance, compatibility, and security. In cybersecurity, keeping VPU drivers updated is crucial, as vulnerabilities in these drivers can be exploited by attackers to gain unauthorized access, execute malicious code, or compromise the confidentiality and integrity of video data. Regular updates and patches help mitigate these risks.
