SignalRGB Local Privilege Escalation via IOCTL
Publication date: 2026-06-17
Last updated on: 2026-06-17
Assigner: CERT/CC
Description
Description
In SignalRGB versions prior to 1.3.7.0, the \\.\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.
