CVE-2018-7550 is fixed in 17 products on 1 platform, first by qemu 1:2.11+dfsg-1ubuntu7.1, released March 11, 2018. It is not reported as exploited. Patch Radar priority: Routine.
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access.
