CVE-2021-47786 describes a kernel-level vulnerability within the Redragon Gaming Mouse driver. This flaw allows attackers to send malformed IOCTL requests, which can lead to a denial of service. By crafting a specific 2000-byte buffer with particular byte patterns directed at the REDRAGON_MOUSE device, the kernel driver can be made to crash. The attack vector is local, requiring low privileges, and the complexity is also low.
With a CVSS score of 6.8, this vulnerability is classified as medium severity, indicating that while it is not critical, it still poses a significant risk. Organizations utilizing the Redragon devices should be aware of the potential for system instability and take proactive steps to mitigate this risk.
The vulnerability was published on January 16, 2026, and its analysis indicates that it has not yet been exploited in the wild. However, organizations should prioritize patching immediately to avoid potential exploitation.
In summary, organizations must be vigilant with their Redragon Gaming Mouse drivers, ensuring that they are updated to the latest versions to prevent denial of service scenarios.
Vulnerability Details
Redragon Gaming Mouse driver contains a kernel-level vulnerability that allows attackers to trigger a denial of service by sending malformed IOCTL requests. Attackers can send a crafted 2000-byte buffer with specific byte patterns to the REDRAGON_MOUSE device to crash the kernel driver.
This vulnerability has a CVSS score of 6.8, indicating a medium level of severity. The affected product includes various firmware versions of the Redragon Gaming Mouse.
Technical Analysis
The root cause of this vulnerability stems from the improper handling of IOCTL requests. Attackers can exploit this weakness by sending specially crafted requests, which causes the driver to crash, leading to denial of service.
The attack vector is local, meaning that an attacker must have physical access to the system or be on the same network. The attack complexity is low, as it does not require significant skill to execute.
No user interaction is required for the attack to succeed, which heightens the risk, as the system can be compromised without any action from the user.
Risk & Impact Analysis
Risk to organizations includes potential system crashes that result from denial of service attacks. The blast radius could affect all users of the Redragon Gaming Mouse, potentially leading to significant downtime and productivity loss.
The urgency of addressing this vulnerability is categorized as medium. Organizations should schedule remediation as part of their patch management cycle to minimize risk.
