QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS.
CVE-2016-1568 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 8.8 High
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
CVE-2013-4526 1 Qemu 1 Qemu 2025-04-12 N/A
Buffer overflow in hw/ide/ahci.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via vectors related to migrating ports.
