CVE-2026-8049
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. Seven of the sixteen IOCTL handlers dereference the SystemBuffer pointer without first verifying that it is non-NULL. Sending an IOCTL with an empty input buffer causes a NULL pointer dereference, resulting in a kernel crash.
