The CVE-2025-XXXX vulnerability affects Qualcomm FastConnect firmware across multiple chipsets, including the FastConnect 6200, 6700, 6800, 6900, and 7800 series. The flaw stems from improper memory handling in the Wi-Fi and Bluetooth stack, where an attacker could trigger a heap-based buffer overflow via crafted wireless packets. This occurs due to insufficient bounds checking when processing high-speed data frames, allowing remote code execution with kernel privileges. The vulnerability is exploitable over-the-air without user interaction, making it highly critical.
