Stack-based buffer overflow in the K7Sentry.sys kernel mode driver (aka K7AV Sentry Device Driver) before 12.8.0.119, as used in multiple K7 Computing products, allows local users to execute arbitrary code with kernel privileges via unspecified vectors.
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.
