|---|---|---|---|---|---|---|---|---|
| CVE-2015-5165 | 0.01 | — | 0.13 | Aug 12, 2015 | The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. | |||
| CVE-2015-3209 | 0.01 | — | 0.10 | Jun 15, 2015 | Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. | |||
| CVE-2024-24474 | Hig | 0.00 | 8.8 | 0.01 | Feb 20, 2024 | 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-2023-42467 | Med | 0.00 | 5.5 | 0.00 | Sep 11, 2023 | QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately. | ||
| CVE-2023-40360 | Med | 0.00 | 5.5 | 0.00 | Aug 14, 2023 | 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-2023-0664 | Hig | 0.00 | 7.8 | 0.00 | Mar 29, 2023 | 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-2022-4172 | Med | 0.00 | 6.5 | 0.00 | Nov 29, 2022 | An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory… | ||
| CVE-2022-3165 | Med | 0.00 | 6.5 | 0.01 | Oct 17, 2022 | 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-2022-2962 | Hig | 0.00 | 7.8 | 0.00 | Sep 13, 2022 | 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… | ||
| CVE-2022-0358 | Hig | 0.00 | 7.8 | 0.00 | Aug 29, 2022 | 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… | ||
| CVE-2022-0216 | Med | 0.00 | 4.4 | 0.00 | Aug 26, 2022 | 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… | ||
| CVE-2022-35414 | Hig | 0.00 | 8.8 | 0.01 | Jul 11, 2022 | 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. NOTE: a third party states that the Non-virtualization Use Case in the qemu.org reference applies here, i.e., "Bugs affecting the… | ||
| CVE-2022-26354 | Low | 0.00 | 3.2 | 0.00 | Mar 16, 2022 | A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results. Affected QEMU versions <= 6.2.0. | ||
| CVE-2022-26353 | Hig | 0.00 | 7.5 | 0.03 | Mar 16, 2022 | 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-2015-7295 | 0.00 | — | 0.05 | Nov 9, 2015 | hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap… | |||

| CVE-2015-5279 | 0.00 | — | 0.01 | Sep 28, 2015 | Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets. | |||
| CVE-2015-3214 | 0.00 | — | 0.02 | Aug 31, 2015 | The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. | |||
| CVE-2015-4037 | 0.00 | — | 0.00 | Aug 26, 2015 | The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program. | |||
| CVE-2015-5166 | 0.00 | — | 0.00 | Aug 12, 2015 | Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. |
