What is CVE-2026-23762?
CVE-2026-23762 is a medium-severity denial of service vulnerability in VB-Audio Software Matrix, published on 22 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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). 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.
Weakness: CWE-755
