Title
CVE-2026-8050
Summary
In SignalRGB versions prior to 1.3.7.0, seven of the thirteen 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.

CVE-2026-8049 (GCVE-0-2026-8049)
Vulnerability from cvelistv5 – Published: 2026-06-17 21:05 – Updated: 2026-06-18 13:12

Title
CVE-2026-8049
Summary
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.
