CVE-2018-9043

CVE-2018-9043 is a denial-of-service vulnerability affecting IObit Advanced SystemCare Ultimate 11.0.1.58. Specifically, the Monitor_win10_x64.sys driver fails to properly validate input, allowing a local attacker to trigger a Blue Screen of Death (BSOD) or potentially achieve other unspecified impacts. Rated with a CVSS score of 7.8 (High), this vulnerability requires local access and low privileges, making it relatively easy to exploit once an attacker is on the system. The potential impact includes high confidentiality, integrity, and availability compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE. Its EPSS score is very low, suggesting a minimal likelihood of exploitation in the wild.
