The Redragon Gaming Mouse driver contains a kernel-level vulnerability (CVE-2021-47786) that allows attackers to trigger a denial of service attack. The vulnerability can be exploited by sending malformed IOCTL requests to the driver. Attackers can craft a specific 2000-byte buffer with particular byte patterns and send it to the REDRAGON_MOUSE device to crash the kernel driver. This represents a significant security risk as it provides a vector for system-level denial of service attacks through a gaming peripheral driver.
