The vulnerability exists in the virtual audio drivers supplied by VB‑Audio, including Voicemeeter Standard, Banana, Potato, Matrix, and Matrix Coconut. When a handle is opened with a specially crafted file attribute, the driver writes an invalid non‑pointer value into the FILE_OBJECT->FsContext field. Subsequent operations that are forwarded down the audio stack can dereference this value, causing a kernel page fault that terminates the system with a BSoD and an access violation status code. The effect is a denial‑of‑service that crashes the operating system; no confidentiality or integrity compromise is described.

VB‑Audio Software provides the affected drivers: Voicemeeter Standard, Banana, Potato and the Matrix and Matrix Coconut drivers. The vulnerable releases are those ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 for the Voicemeeter family and 1.0.2.2 and 2.0.2.2 for the Matrix family. No other vendors or versions are reported as impacted.

The CVSS score of 6.9 indicates medium severity. The EPSS score is below 1 %, suggesting a low probability of exploitation. The vulnerability is not present in the CISA KEV catalog. Attackers must have local, non‑privileged access to a Windows system and the ability to open the driver with the special file attribute. The flaw results in a kernel crash, so the chief risk is service disruption rather than data compromise.
