Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c in QEMU before 1.7.2 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via crafted (1) cmd_len, (2) row, or (3) col values; (4) row_start and row_end values; or (5) col_star and col_end values in a savevm image.
CVE-2015-8817 2 Qemu, Redhat 2 Qemu, Openstack 2025-04-12 N/A
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions >= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.

QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It could occur while reading Interrupt Mask Registers (IMR). A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2016-7155 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 4.4 Medium
hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds access or infinite loop, and QEMU process crash) via a crafted page count for descriptor rings.

QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.
