Summary

CVE-2026-23764 is a medium-severity Use of Out-of-range Pointer Offset (CWE-823) vulnerability in Vb Audio (inferred from references). Its CVSS base score is 6.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

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 allocate non-paged pool and map it into user space, where a length value associated with the allocation is exposed and can be modified by an unprivileged local attacker. On subsequent IOCTL handling, the corrupted length is used directly as the IoAllocateMdl length argument without adequate integrity checks before building and mapping the MDL, which can cause a kernel crash (BSoD), typically PAGE_FAULT_IN_NONPAGED_AREA. This flaw allows a local user to trigger a denial-of-service on affected Windows systems.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including static analysis and fuzzing) directly finds unsafe pointer arithmetic before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development standards and tools can mandate safe pointer usage and compiler/runtime checks that stop the weakness from being introduced.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles can require bounds-checked pointer arithmetic or safe language constructs that structurally avoid out-of-range offsets.

SC-39 Process Isolation partial match

Process isolation confines damage from invalid pointer offsets to a single address space, reducing overall impact.

SI-16 Memory Protection partial match

Memory-protection controls limit the blast radius of an out-of-range pointer dereference without preventing or detecting the coding error itself.

Secure architecture principles promote safe pointer handling and memory layout controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid unsafe pointer arithmetic and require bounds checks.
