It is on the public LOLDrivers list for the kernel access surface. If you have an ASUS motherboard with GameFirst or PC Probe installed, the driver is expected. Update the ASUS software suite to the current version.

What the record shows

iomap64.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.
