| CVE-2023-2680 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-12-28 | N/A | 8.2 HIGH |
| This CVE exists because of an incomplete fix for CVE-2021-3750. More specifically, the qemu-kvm package as released for Red Hat Enterprise Linux 9.1 via RHSA-2022:7967 included a version of qemu-kvm that was actually missing the fix for CVE-2021-3750. | |||||
| CVE-2023-2861 | 1 Qemu | 1 Qemu | 2023-12-11 | N/A | 7.1 HIGH |
| A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. The 9pfs server did not prohibit opening special files on the host side, potentially allowing a malicious client to escape from the exported 9p tree by creating and opening a device file in the shared folder. | |||||
| CVE-2023-5088 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-12-08 | N/A | 7.0 HIGH |
| A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot. | |||||
| CVE-2023-1386 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2023-08-01 | N/A | 7.8 HIGH |
| A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their privileges within the guest and help a host local user to elevate privileges on the host. | |||||
| CVE-2022-35414 | 1 Qemu | 1 Qemu | 2022-07-18 | 6.1 MEDIUM | 8.8 HIGH |
| softmmu/physmem.c in QEMU through 7.0.0 can perform an uninitialized read on the translate_fail path, leading to an io_readx or io_writex crash. | |||||
| CVE-2021-3750 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2022-06-24 | 4.6 MEDIUM | 8.2 HIGH |
| A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host. This flaw affects QEMU versions before 7.0.0. | |||||
| CVE-2022-26353 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-06-03 | 5.0 MEDIUM | 7.5 HIGH |
| A flaw was found in the virtio-net device of QEMU. This flaw was inadvertently introduced with the fix for CVE-2021-3748, which forgot to unmap the cached virtqueue elements on error, leading to memory leakage and other unexpected results. Affected QEMU version: 6.2.0. | |||||
| CVE-2021-3748 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2022-05-13 | 7.2 HIGH | 8.8 HIGH |
| A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. | |||||
| CVE-2021-4207 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2022-05-10 | 4.6 MEDIUM | 8.8 HIGH |
| A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. | |||||
| CVE-2021-4206 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2022-05-10 | 4.6 MEDIUM | 8.2 HIGH |
| A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. | |||||
| CVE-2022-1050 | 1 Qemu | 1 Qemu | 2022-04-29 | 4.6 MEDIUM | 8.8 HIGH |
| 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. | |||||
| CVE-2021-20181 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-04-26 | 6.9 MEDIUM | 7.5 HIGH |
| A race condition flaw was found in the 9pfs server implementation of QEMU up to and including 5.2.0.

| hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash. | |||||
| CVE-2021-3546 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2021-11-06 | 4.6 MEDIUM | 8.2 HIGH |
| An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service condition, or potential code execution with the privileges of the QEMU process. | |||||
| CVE-2021-3682 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2021-10-18 | 6.0 MEDIUM | 8.5 HIGH |
| A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host. | |||||
| CVE-2021-3713 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2021-10-18 | 4.6 MEDIUM | 7.4 HIGH |
| An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host. | |||||
