What is CVE-2025-58347?

A buffer overflow vulnerability has been identified in the Wi-Fi driver component of Samsung's Mobile and Wearable Processors, specifically in the Exynos 980, 850, 1080, 1280, 2200, 1330, 1380, 1480, 1580, and the wearable models W920, W930, and W1000. The issue stems from unbounded memory allocation during a write operation to /proc/driver/unifi0/p2p_certif, which can result in significant kernel memory exhaustion, potentially compromising system stability and integrity.
