| CVE-2022-3872 | 1 Qemu | 1 Qemu | 2024-08-03 | 8.6 High |
| An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | ||||
| CVE-2022-3165 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2024-08-03 | 6.5 Medium |
| An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service. | ||||
| CVE-2022-1050 | 1 Qemu | 1 Qemu | 2024-08-02 | 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-2022-0358 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2024-08-02 | 7.8 High |
| A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system. | ||||
| CVE-2022-0216 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-08-02 | 4.4 Medium |
| A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service. | ||||
| CVE-2023-40360 | 1 Qemu | 1 Qemu | 2024-08-02 | 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-2023-4135 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2024-08-02 | 6 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-2023-3354 | 3 Fedoraproject, Qemu, Redhat | 10 Fedora, Qemu, Advanced Virtualization and 7 more | 2024-08-02 | 7.5 High |
| A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service. | ||||
| CVE-2023-2861 | 1 Qemu | 1 Qemu | 2024-08-02 | 6 Medium |
| 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-2023-2680 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2024-08-02 | 7.5 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-2023-1544 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-08-02 | 6 Medium |
| A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU. | ||||
| CVE-2023-0664 | 4 Fedoraproject, Microsoft, Qemu and 1 more | 4 Fedora, Windows, Qemu and 1 more | 2024-08-02 | 7.8 High |
| A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges on the system. | ||||
| CVE-2023-0330 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-08-02 | 5.3 Medium |
| A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem may lead to memory corruption bugs like stack overflow or use-after-free. | ||||
| CVE-2024-26327 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-08-02 | 5.3 Medium |
| An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c mishandles the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF implementations. | ||||
