hw/input/ps2.c in Qemu does not validate 'rptr' and 'count' values during guest migration, leading to out-of-bounds access.
CVE-2017-8112 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 4.9 MEDIUM 6.5 MEDIUM
hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count.
CVE-2017-10806 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 2.1 LOW 5.5 MEDIUM
Stack-based buffer overflow in hw/usb/redirect.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (QEMU process crash) via vectors related to logging debug messages.
CVE-2017-9373 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 1.9 LOW 5.5 MEDIUM
Memory leak in QEMU (aka Quick Emulator), when built with IDE AHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the AHCI device.
CVE-2016-9381 2 Citrix, Qemu 2 Xenserver, Qemu 2025-04-20 6.9 MEDIUM 7.5 HIGH
Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability.
CVE-2017-8284 1 Qemu 1 Qemu 2025-04-20 6.9 MEDIUM 7.0 HIGH
** DISPUTED ** The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes."
CVE-2017-13673 1 Qemu 1 Qemu 2025-04-20 4.0 MEDIUM 6.5 MEDIUM
The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function.
CVE-2017-9503 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 1.9 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator), when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving megasas command processing.
CVE-2017-17381 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 2.1 LOW 6.5 MEDIUM
The Virtio Vring implementation in QEMU allows local OS guest users to cause a denial of service (divide-by-zero error and QEMU process crash) by unsetting vring alignment while updating Virtio rings.
CVE-2017-5931 1 Qemu 1 Qemu 2025-04-20 7.2 HIGH 8.8 HIGH
Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow.
CVE-2015-7504 3 Debian, Qemu, Xen 3 Debian Linux, Qemu, Xen 2025-04-20 4.6 MEDIUM 8.8 HIGH
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode.
CVE-2022-4172 1 Qemu 1 Qemu 2025-04-14 N/A 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 4 Extra Packages For Enterprise Linux, Fedora, Qemu and 1 more 2025-04-14 N/A 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-2014-7840 2 Qemu, Redhat 8 Qemu, Enterprise Linux, Enterprise Linux Desktop and 5 more 2025-04-12 7.5 HIGH N/A
The host_from_stream_offset function in arch_init.c in QEMU, when loading RAM during migration, allows remote attackers to execute arbitrary code via a crafted (1) offset or (2) length value in savevm data.
CVE-2016-9776 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator) built with the ColdFire Fast Ethernet Controller emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could use this issue to crash the QEMU process on the host leading to DoS.
CVE-2016-8669 4 Debian, Opensuse, Qemu and 1 more 6 Debian Linux, Leap, Qemu and 3 more 2025-04-12 2.1 LOW 6.0 MEDIUM
The serial_update_parameters function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving a value of divider greater than baud base.
CVE-2011-4111 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Enterprise Linux Server Supplementary 2025-04-12 6.8 MEDIUM N/A
Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.
