| 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-2023-4135 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2023-12-11 | N/A | 6.5 MEDIUM |
| A heap out-of-bounds memory read flaw was found in the virtual nvme device in QEMU. The QEMU process does not validate an offset provided by the guest before computing a host heap pointer, which is used for copying data back to the guest. Arbitrary heap memory relative to an allocated buffer can be disclosed. | |||||
| CVE-2023-40360 | 1 Qemu | 1 Qemu | 2023-12-11 | N/A | 5.5 MEDIUM |
| QEMU through 8.0.4 accesses a NULL pointer in nvme_directive_receive in hw/nvme/ctrl.c because there is no check for whether an endurance group is configured before checking whether Flexible Data Placement is enabled. | |||||
| CVE-2021-3947 | 1 Qemu | 1 Qemu | 2023-11-21 | 2.1 LOW | 5.5 MEDIUM |
| A stack-buffer-overflow was found in QEMU in the NVME component. The flaw lies in nvme_changed_nslist() where a malicious guest controlling certain input can read out of bounds memory. A malicious user could use this flaw leading to disclosure of sensitive information. | |||||
| CVE-2023-3180 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2023-11-07 | N/A | 6.5 MEDIUM |
| A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ. | |||||
| CVE-2023-3301 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2023-11-07 | N/A | 5.6 MEDIUM |
| A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this time window to trigger an assertion and cause a denial of service. | |||||
| CVE-2021-3607 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2023-11-07 | 4.9 MEDIUM | 6.0 MEDIUM |
| An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3545 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-11-07 | 2.1 LOW | 6.5 MEDIUM |
| An information disclosure 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 exists in virgl_cmd_get_capset_info() in contrib/vhost-user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit this issue to leak memory from the host. | |||||
| CVE-2021-20221 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2023-11-07 | 2.1 LOW | 6.0 MEDIUM |
| An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario. | |||||
| CVE-2021-20181 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-11-07 | 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. This flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity as well as system availability. | |||||
| CVE-2020-27821 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-11-07 | 2.1 LOW | 6.0 MEDIUM |
| A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial of service. This flaw affects QEMU versions prior to 5.2.0. | |||||
| CVE-2020-27661 | 1 Qemu | 1 Qemu | 2023-11-07 | 2.1 LOW | 6.5 MEDIUM |
| A divide-by-zero issue was found in dwc2_handle_packet in hw/usb/hcd-dwc2.c in the hcd-dwc2 USB host controller emulation of QEMU. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service. | |||||
| CVE-2020-1711 | 4 Debian, Opensuse, Qemu and 1 more | 5 Debian Linux, Leap, Qemu and 2 more | 2023-11-07 | 6.0 MEDIUM | 6.0 MEDIUM |
| An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host. | |||||

A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. | |||||
| CVE-2020-14394 | 3 Fedoraproject, Qemu, Redhat | 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more | 2023-11-07 | N/A | 3.2 LOW |
| An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service. | |||||
| CVE-2020-14364 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2023-11-07 | 4.4 MEDIUM | 5.0 MEDIUM |
| An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. | |||||
