CVE-2026-8050: CWE-476 NULL Pointer Dereference in SignalRGB SignalRGB kernel driver
CVE-2026-8050 is a vulnerability in the SignalRGB kernel driver where multiple IOCTL handlers dereference a NULL pointer without validation. This occurs in SignalRGB versions prior to 1.3.7.0 when an IOCTL is sent with an empty input buffer, causing a kernel crash.
AI Analysis
Technical Summary
The SignalRGB kernel driver versions before 1.3.7.0 contain a NULL pointer dereference vulnerability (CWE-476) in seven out of thirteen IOCTL handlers. These handlers do not verify that the SystemBuffer pointer is non-NULL before dereferencing it. An attacker can trigger this by sending an IOCTL request with an empty input buffer, leading to a kernel crash due to the NULL pointer dereference.
Potential Impact
Successful exploitation results in a denial of service via a kernel crash. There is no indication of code execution or privilege escalation from the provided data. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is documented in the provided information. Users should monitor the vendor advisory for updates and apply any official patches once available.
