Detailsinfo

A vulnerability was found in VB-Audio Voicemeeter, Voicemeeter Banana, Voicemeeter Potato, Matrix and Matrix Coconut. It has been declared as problematic. This vulnerability affects an unknown code block of the component Virtual Audio Driver. The manipulation with an unknown input leads to a exceptional condition vulnerability. The CWE definition for the vulnerability is CWE-755. The product does not handle or incorrectly handles an exceptional condition. As an impact it is known to affect availability. CVE summarizes:

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). The drivers map non-paged pool memory into user space via MmMapLockedPagesSpecifyCache using UserMode access without proper exception handling. If the mapping fails, such as when a process has exhausted available virtual address space, MmMapLockedPagesSpecifyCache raises an exception that is not caught, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_NO_MEMORY. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems.

The weakness was published by Klaus Hahnenkamp. The advisory is shared for download at github.com. This vulnerability was named CVE-2026-23762 since 01/15/2026. The exploitation appears to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available.
