InpOut direct port I/O driver

From Highrez (InpOut)

Status

On a known-vulnerable list

Known variants

3 distinct hashes

Field notes

InpOutx64.sys is a small open driver that grants direct hardware port input and output. Many third-party hardware, RGB, and overclocking utilities embed it because it gives a no-fuss way to read or write hardware ports from user mode. It is on the LOLDrivers list because of that direct access.

Its presence usually means one of those bundled utilities is installed.

What the record shows

inpoutx64.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.

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.
