atillk64.sys
ASRock low-level hardware driver
ATILLK64.sys is a kernel driver used by ASRock's RGB LED, A-Tuning, F-Stream, and related motherboard utilities to program and query the embedded integrated circuits on ASRock hardware. It is on the LOLDrivers list as part of a 2018 cluster of ASRock driver vulnerabilities (CVE-2018-10709 through CVE-2018-10712) that exposed IOCTLs with insufficient access control, allowing local privilege escalation.
It is common on systems with ASRock motherboards running ASRock software. Updating ASRock's current utilities is the practical step.
atillk64.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.
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.
