A NULL pointer dereference bug in the function ObReferenceObjectByHandle in the Kingsoft Internet Security 9+ kernel driver KWatch3.sys allows local non-privileged users to crash the system via IOCTL 0x80030030.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
