Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations.
Qemu VGA module allows guest to edit certain registers in 'vbe' and 'vga' modes.
A privileged guest user could use CVE-2016-3710 to exceed the bank address window and write beyond the said memory area, potentially leading to arbitrary code execution with privileges of the Qemu process. If the system is not using stubdomains, this will be in domain 0.
A privileged guest user could use CVE-2016-3712 to cause potential integer overflow or OOB read access issues in Qemu, resulting in a DoS of the guest itself. More dangerous effect, such as data leakage or code execution, are not known but cannot be ruled out.
