OpenRazer is an open source driver and userspace daemon used to control Razer lighting and other functions on GNU/Linux. Used to control Razer lighting and other features on GNU/Linux, a buffer overflow vulnerability exists in OpenRazer version 3.3.0 and earlier, which stems from a boundary error in the razeraccessory driver when handling untrusted input. An attacker could exploit this vulnerability to cause a denial of service (DoS) via a specially crafted buffer sent to the matrix_custom_frame device.
