CVE-2026-8050
No Score
Description
SignalRGB is a Windows application used for RGB lighting control and hardware monitoring. Its kernel component, SignalIo.sys, provides the low-level interfaces required to access and interact with hardware resources. he \\.\SignalIo device object is created without an explicit SDDL security descriptor and without FILE_DEVICE_SECURE_OPEN. This results in overly permissive default access control, allowing any authenticated local user to obtain a handle to the device and issue privileged IOCTLs.
