KAVSafe.sys 2010.4.14.609 and earlier, as used in Kingsoft Webshield 3.5.1.2 and earlier, allows local users to overwrite arbitrary kernel memory via a crafted request to IOCTL 0x830020d4 on the KAVSafe device.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
