The usb_device_post_load function in hw/usb/bus.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted savevm image, related to a negative setup_len or setup_index value.
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.
