iomem64.sys
ASUS PC Probe I/O memory driver
iomem64.sys is a kernel driver from ASUS, used by PC Probe and related motherboard monitoring and fan-control utilities. The driver provides low-level I/O memory access so the utility can read sensor data and manage hardware.
CVE-2024-41498 documents an arbitrary physical RAM read/write vulnerability: any local process can read and write physical memory through the driver's IOCTL interface. This is the same class of vulnerability that affects many hardware monitoring drivers, but here the access surface is particularly broad.
If you have an ASUS motherboard with the vendor monitoring utilities installed, the driver is expected. Update the ASUS software suite to the current version.
iomem64.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.
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.
