| CVE-2022-3165 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2025-05-14 | N/A | 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-2024-26328 | 1 Qemu | 1 Qemu | 2025-05-07 | N/A | 6.0 MEDIUM |
| An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled. | |||||
| CVE-2024-26327 | 1 Qemu | 1 Qemu | 2025-05-07 | N/A | 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. | |||||
| CVE-2024-3567 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-05-06 | N/A | 5.5 MEDIUM |
| A flaw was found in QEMU. An assertion failure was present in the update_sctp_checksum() function in hw/net/net_tx_pkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition. | |||||
| CVE-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2025-05-06 | N/A | 4.9 MEDIUM |
| A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak. | |||||
| CVE-2022-3872 | 1 Qemu | 1 Qemu | 2025-05-05 | N/A | 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-2023-6683 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-05-02 | N/A | 6.5 MEDIUM |
| A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service. | |||||
| CVE-2022-2962 | 1 Qemu | 1 Qemu | 2025-04-23 | N/A | 7.8 HIGH |
| 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 multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | |||||
| CVE-2016-10155 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 4.9 MEDIUM | 6.0 MEDIUM |

| CVE-2017-9310 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 1.9 LOW | 5.6 MEDIUM |
| QEMU (aka Quick Emulator), when built with the e1000e NIC emulation support, allows local guest OS privileged users to cause a denial of service (infinite loop) via vectors related to setting the initial receive / transmit descriptor head (TDH/RDH) outside the allocated descriptor buffer. | |||||
| CVE-2015-7549 | 1 Qemu | 1 Qemu | 2025-04-20 | 2.1 LOW | 6.0 MEDIUM |
| The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure to define the .write method. | |||||
