openlibsys.sys

OpenLibSys hardware-monitoring driver (early lineage)

From OpenLibSys (open source)

Status

On a known-vulnerable list

Known variants

2 distinct hashes

Field notes

openlibsys.sys is an early-lineage hardware-monitoring driver from the same OpenLibSys project that produced the more famous WinRing0 and WinRing0x64 drivers. Same broad hardware-access design, same reason for being on the LOLDrivers list.

Its presence is rare on a current system; if you find it, it almost always traces back to an older third-party utility that bundled the OpenLibSys driver before WinRing0 was the project's standard name.

What the record shows

openlibsys.sys is listed as a known-vulnerable driver on the public LOLDrivers project. 2 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.
