漏洞关键信息 漏洞标题 VB-Audio Voicemeeter & Matrix Drivers DoS via MmMapLockedPagesSpecifyCache 严重程度 MEDIUM 发布日期 January 22, 2026 漏洞编号 CVE-2026-23762 漏洞描述 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 (vbvoicemeetervai64.sys, vbmatrixvai64.sys, vbaudio_vmauxvai.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.
