| CVE-2024-3447 | 2 Netapp, Qemu | 2 Hci Compute Node, Qemu | 2025-11-03 | N/A | 6.0 MEDIUM |
|
A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s->data_count` and the size of `s->fifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

| CVE-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2025-11-03 | 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-2023-5088 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-11-03 | N/A | 6.4 MEDIUM |
|
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-2023-1544 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2025-11-03 | N/A | 6.0 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-2024-7730 | 1 Qemu | 1 Qemu | 2025-08-05 | N/A | 7.4 HIGH |
|
A heap buffer overflow was found in the virtio-snd device in QEMU. When reading input audio in the virtio-snd input callback, virtio_snd_pcm_in_cb, the function did not check whether the iov can fit the data buffer. This issue can trigger an out-of-bounds write if the size of the virtio queue element is equal to virtio_snd_pcm_status, which makes the available space for audio data zero.

| CVE-2024-24474 | 1 Qemu | 1 Qemu | 2025-06-25 | N/A | 8.8 HIGH |
|
QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len.
|
|||||
| CVE-2022-3165 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2025-05-14 | N/A | 6.5 MEDIUM |

| 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-2024-3567 | 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-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.
