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."},{"lang":"es","value":"VB-Audio Voicemeeter, Voicemeeter Banana y Voicemeeter Potato (versiones que terminan en 1.1.1.9, 2.1.1.9 y 3.1.1.9 y anteriores, respectivamente), así como VB-Audio Matrix y Matrix Coconut (versiones que terminan en 1.0.2.2 y 2.0.2.2 y anteriores, respectivamente), contienen una vulnerabilidad en sus controladores de audio virtuales (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys y vbaudio_vmvaio3*.sys). Cuando se abre un identificador con un valor de atributo de archivo especial, los controladores inicializan incorrectamente FILE_OBJECT->FsContext a un valor mágico no puntero. Si las operaciones subsiguientes no son manejadas por el controlador de VB-Audio y son reenviadas a la pila de controladores de audio (por ejemplo, a través de PortCls a ks.sys), el valor FsContext inválido puede ser desreferenciado, causando un fallo del kernel (BSoD), típicamente SYSTEM_SERVICE_EXCEPTION con STATUS_ACCESS_VIOLATION.
