CVE-2024-7730 (GCVE-0-2024-7730)
Vulnerability from cvelistv5 – Published: 2024-11-14 12:11 – Updated: 2024-11-14 19:32
VLAI?
Summary
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-2024-3447 (GCVE-0-2024-3447)
Vulnerability from cvelistv5 – Published: 2024-11-14 12:10 – Updated: 2025-11-03 19:29

Summary
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-2024-6505 (GCVE-0-2024-6505)
Vulnerability from cvelistv5 – Published: 2024-07-05 13:51 – Updated: 2025-11-08 07:13
VLAI?
Summary
A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host.

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-2024-24474 (GCVE-0-2024-24474)

VLAI?
Summary
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-2023-6683 (GCVE-0-2023-6683)
Vulnerability from cvelistv5 – Published: 2024-01-12 19:01 – Updated: 2025-11-08 07:10
VLAI?
Summary
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.
Severity ?
6.5 (Medium)

CVE-2023-6693 (GCVE-0-2023-6693)
Vulnerability from cvelistv5 – Published: 2024-01-02 09:15 – Updated: 2025-11-06 21:45
VLAI?
Summary
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.

Summary
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-2023-5088 (GCVE-0-2023-5088)
Vulnerability from cvelistv5 – Published: 2023-11-03 13:58 – Updated: 2025-11-06 22:57
VLAI?
Summary
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.
Severity ?
6.4 (Medium)
CWE

CVE-2023-3255 (GCVE-0-2023-3255)
Vulnerability from cvelistv5 – Published: 2023-09-13 16:12 – Updated: 2025-11-08 06:30
VLAI?
Summary
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard to the VNC server to trigger a denial of service.
Severity ?
6.5 (Medium)
CWE
- CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Summary
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-2023-42467 (GCVE-0-2023-42467)
Vulnerability from cvelistv5 – Published: 2023-09-11 00:00 – Updated: 2024-09-26 17:36
VLAI?
Summary
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.

Summary
The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS. Note: This has been disputed by multiple third parties as not a valid vulnerability due to the rocker device not falling within the virtualization use case.

Summary
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-2023-1386 (GCVE-0-2023-1386)
Vulnerability from cvelistv5 – Published: 2023-07-24 15:19 – Updated: 2024-09-25 19:57
VLAI?
Summary
A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their privileges within the guest and help a host local user to elevate privileges on the host.

CVE-2023-3354 (GCVE-0-2023-3354)
Vulnerability from cvelistv5 – Published: 2023-07-11 16:16 – Updated: 2025-02-13 16:55
VLAI?
Summary
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.
Severity ?
7.5 (High)
CWE
