CVE-2022-4172 3 Fedoraproject, Qemu, Redhat 3 Fedora, Qemu, Enterprise Linux 2025-04-14 6.5 Medium
An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
CVE-2022-4144 3 Fedoraproject, Qemu, Redhat 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more 2025-04-14 6.5 Medium
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
CVE-2016-7161 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 9.8 Critical
Heap-based buffer overflow in the .receive callback of xlnx.xps-ethernetlite in QEMU (aka Quick Emulator) allows attackers to execute arbitrary code on the QEMU host via a large ethlite packet.
CVE-2016-7157 1 Qemu 1 Qemu 2025-04-12 4.4 Medium
The (1) mptsas_config_manufacturing_1 and (2) mptsas_config_ioc_0 functions in hw/scsi/mptconfig.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via vectors involving MPTSAS_CONFIG_PACK.
CVE-2016-2538 1 Qemu 1 Qemu 2025-04-12 N/A
Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function.
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.
