Field notes

vmdrv.sys is the kernel driver for Voicemod, the popular real-time voice changer used by gamers, streamers, and content creators. The driver installs as a virtual audio device so Voicemod can intercept and transform audio before it reaches Discord, OBS, or the game.

It is on the public LOLDrivers list for the kernel access surface of the virtual device driver. If you use Voicemod, the driver is expected. Keep the application updated.

What the record shows

vmdrv.sys is listed as a known-vulnerable driver on the public LOLDrivers project. 3 distinct binary hashes matching this filename are on record, meaning multiple versions of the file have been observed.

What this means, plainly

Presence is not proof of misuse. Driver files on the LOLDrivers list commonly ship with legitimate hardware tools, gaming software, or vendor utilities. Their presence is recorded as evidence on a record. It is never treated as a verdict about a person.

Source

Status data comes from the public LOLDrivers project, a community-curated registry of drivers known to be vulnerable or malicious. The snapshot Vera uses was refreshed July 10, 2026. CVE links go to the NIST National Vulnerability Database.
