Описание
The address_space_write_continue function in exec.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds access and guest instance crash) by leveraging use of qemu_map_ram_ptr to access guest ram block area.
Quick Emulator (QEMU), compiled with qemu_map_ram_ptr to access guests' RAM block area, is vulnerable to an OOB r/w access issue. The crash can occur if a privileged user inside a guest conducts certain DMA operations, resulting in a DoS.
