Known variants

1 distinct hashes

Field notes

asmmap.sys is the 32-bit companion to asmmap64.sys, an ASUS kernel driver that provides physical memory mapping for UEFI updates and system management utilities. It allows unprivileged users to read and write all physical memory and execute direct I/O operations.

See the asmmap64.sys entry for context. If you have an ASUS motherboard with vendor utilities, the driver is expected. Update the ASUS software suite to the current version.

What the record shows

asmmap.sys is listed as a known-vulnerable driver on the public LOLDrivers project. One distinct binary hash matching this filename is on record.

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.
