Google has released its February 2024 Android security update, addressing 48 vulnerabilities, including an actively exploited zero-day flaw in the system’s USB driver. This comprehensive security patch represents a significant response to emerging threats in the Android ecosystem, with particular emphasis on critical system components.
Zero-Day Vulnerability in Android USB Driver: Technical Analysis
The most critical issue addressed in this update is CVE-2024-53104, a zero-day vulnerability affecting the USB Video Class driver in the Android kernel. The flaw stems from improper frame handling within the uvc_parse_format function, specifically when processing UVC_VS_UNDEFINED frames. This implementation error leads to incorrect framebuffer size calculations, potentially resulting in out-of-bounds write operations that compromise system security.
Impact Assessment and Attack Vectors
Security researchers have confirmed that successful exploitation of CVE-2024-53104 enables local attackers to elevate their privileges within the Android system. This vulnerability creates a pathway for arbitrary code execution and potential denial-of-service attacks, posing significant risks to device integrity and user data security.
Qualcomm WLAN Component Vulnerability
Another significant security issue addressed in this update is CVE-2024-45569, affecting Qualcomm’s WLAN component. This vulnerability is particularly concerning as it enables remote code execution without requiring user interaction or elevated privileges. The flaw originates from improper array index validation during ML IE processing in WLAN host communications.
Security Update Implementation Strategy
Google has implemented a dual-level patch distribution strategy for February 2024. The initial patch level (2025-02-01) addresses core system vulnerabilities, while the secondary level (2025-02-05) focuses on vendor-specific components and kernel-level issues. Device manufacturers are required to implement both patch levels to ensure comprehensive protection against all identified vulnerabilities.
The severity of these security issues, particularly the actively exploited zero-day vulnerability, necessitates immediate action from Android users. Security experts strongly recommend installing available updates promptly to mitigate potential exploitation risks. Organizations and individuals should prioritize regular security updates as a fundamental aspect of their mobile security strategy, ensuring protection against emerging cyber threats in the increasingly complex mobile threat landscape.
