Detailed vulnerability description

The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.

The weakness exists in the load_multiboot function in hw/i386/multiboot.c due to integer overflow. An adjacent attacker can execute arbitrary code via specially crafted multiboot header address values, which trigger an out-of-bounds write.

Successful exploitation of the vulnerability may result in system compromise.
