Memory leak exploitation in Almico Speedfan 4.52 is constrained to local, high-privilege access and produces limited availability degradation via the speedfan.sys kernel driver's MSR Index Handler. The vulnerability resides in the KiSystemCall64 handler path within speedfan.sys, where kernel pool memory is allocated but never released during MSR index processing, enabling gradual resource exhaustion on affected Windows hosts. A publicly available proof-of-concept exists, no vendor patch has been issued, and the vendor has not responded to coordinated disclosure.
There is a local privilege escalation vulnerability in Alfredo Milani Comparetti SpeedFan 4.52. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
