Heap-based buffer overflow in the vrend_create_vertex_elements_state function in vrend_renderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and crash) via the num_elements parameter.
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.
