The SDDisk2k.sys driver of WinMagic SecureDoc v8.5 and earlier allows local users to write to arbitrary kernel memory addresses because the IOCTL dispatcher lacks pointer validation. Exploiting this vulnerability results in privileged code execution.
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.
