| CVE-2023-5088 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-06-12 | 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-2025-47712 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-06-09 | 4.3 Medium |
| A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service. | ||||
| CVE-2025-47711 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-06-09 | 4.3 Medium |
| There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-of-service. | ||||
| CVE-2024-7409 | 1 Redhat | 4 Advanced Virtualization, Enterprise Linux, Openshift and 1 more | 2025-06-03 | N/A |
| A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. | ||||
| CVE-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2025-05-21 | 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-2024-8612 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-05-21 | 3.8 Low |
| A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for virtqueue_push as set in virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete could be larger than the true size of the data which has been sent to guest. Once virtqueue_push() finally calls dma_memory_unmap to ummap the in_iov, it may call the address_space_write function to write back the data. Some uninitialized data may exist in the bounce.buffer, leading to an information leak. | ||||
| CVE-2024-8354 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-21 | 5.5 Medium |
| A flaw was found in QEMU. An assertion failure was present in the usb_ep_get() function in hw/net/core.c when trying to get the USB endpoint from a USB device. This flaw may allow a malicious unprivileged guest user to crash the QEMU process on the host and cause a denial of service condition. | ||||
| CVE-2024-8235 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Libvirt | 2025-05-21 | 6.2 Medium |
| A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon. | ||||
| CVE-2024-7383 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-05-21 | 7.4 High |
| A flaw was found in libnbd. The client did not always correctly verify the NBD server's certificate when using TLS to connect to an NBD server. This issue allows a man-in-the-middle attack on NBD traffic. | ||||
| CVE-2024-6505 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-21 | 6.8 Medium |
| 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. | ||||
| CVE-2024-4467 | 1 Redhat | 7 Advanced Virtualization, Container Native Virtualization, Enterprise Linux and 4 more | 2025-05-21 | 7.8 High |
| A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file. | ||||
| CVE-2024-3567 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-06 | 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-2024-3446 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-05-02 | 8.2 High |
| A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host. | ||||
| CVE-2022-40284 | 4 Debian, Fedoraproject, Redhat and 1 more | 9 Debian Linux, Fedora, Advanced Virtualization and 6 more | 2025-05-02 | 7.8 High |
| A buffer overflow was discovered in NTFS-3G before 2022.10.3. Crafted metadata in an NTFS image can cause code execution. A local attacker can exploit this if the ntfs-3g binary is setuid root. A physically proximate attacker can exploit this if NTFS-3G software is configured to execute upon attachment of an external storage device. | ||||
| CVE-2023-6683 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-02 | 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-2024-3447 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-04-25 | 6 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-2024-4418 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Rhel Eus | 2025-04-11 | 6.2 Medium |
| A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame was concurrently being "freed" when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged user to access virtproxyd without authenticating. Remote users would need to authenticate before they could access it. | ||||
| CVE-2024-1441 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-04-11 | 5.5 Medium |
| An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash. | ||||
| CVE-2024-2496 | 2 Debian, Redhat | 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more | 2025-04-09 | 5 Medium |
| A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by causing the libvirt daemon to crash. | ||||
| CVE-2021-4207 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2025-03-21 | 8.2 High |
| A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. | ||||
