CVE-2016-1568

CVE-2016-1568 is a use-after-free in QEMU’s AHCI emulation (hw/ide/ahci.c) when IDE AHCI Emulation is enabled. A guest user can cause a denial of service (QEMU process crash) and potentially execute arbitrary code via an invalid AHCI NCQ AIO command. The issue is triggered by use-after-free in NC...
