CVSSv3
CVE-2020-10717
A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descripto...

CVSSv3
CVE-2020-25742
pci_change_irq_level in hw/pci/pci.c in QEMU prior to 5.1.1 has a NULL pointer dereference because pci_get_bus() might not return a valid pointer.

CVSSv3
CVE-2020-11869
An integer overflow was found in QEMU 4.0.1 up to and including 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could...

CVE-2019-20175
An issue exists in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 up to and including 4.2.0. The guest system can crash the QEMU process in the host system via a special SCSI_IOCTL_SEND_COMMAND. It hits an assertion that implies that the size of successful DMA transfers there must b...

CVSSv3
CVE-2023-42467
QEMU up to and including 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately.

CVSSv3
CVE-2021-20263
A flaw was found in the virtio-fs shared file system daemon (virtiofsd) of QEMU. The new 'xattrmap' option may cause the 'security.capability' xattr in the guest to not drop on file write, potentially leading to a modified, privileged executable in the guest. ...

CVE-2022-1050
A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition.

CVSSv3
CVE-2022-2962
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers ...
