CVE-2010-5164: Kingsoft Personal Firewall 9

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

Race condition in KingSoft Personal Firewall 9 Plus 2009.05.07.70 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute
