CVE-2018-8060

HWiNFO AMD64 Kernel driver (version 8.98 and earlier) is affected. An unprivileged user can send an IOCTL to the device driver, and if input/output buffers are NULL or data is invalid, a NULL/invalid pointer access occurs, causing a Windows kernel panic (BSOD). Affected IOCTLs are higher than 0x8...
