Overview
CVE-2026-23761 is a known-severity vulnerability. It was published on January 22, 2026.
Technical description
VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). When a handle is opened with a special file attribute value, the drivers improperly initialize FILE_OBJECT->FsContext to a non-pointer magic value. If subsequent operations are not handled by the VB-Audio driver and are forwarded down the audio driver stack (e.g., via PortCls to ks.sys), the invalid FsContext value can be dereferenced, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_ACCESS_VIOLATION. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems.
