CVE-2024-4693 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Rhel Els 2026-11-05 5.5 Medium
A flaw was found in the QEMU Virtio PCI Bindings (hw/virtio/virtio-pci.c). An improper release and use of the irqfd for vector 0 during the boot process leads to a guest triggerable crash via vhost_net_stop(). This flaw allows a malicious guest to crash the QEMU process on the host.
CVE-2024-3567 2 Qemu, Redhat 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more 2026-11-05 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-2024-2496 2 Debian, Redhat 5 Debian Linux, Advanced Virtualization, Enterprise Linux and 2 more 2026-11-05 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-2024-2494 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Rhel Els 2026-11-05 6.2 Medium
A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash.
CVE-2024-1441 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Rhel Els 2026-11-05 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-2023-6693 3 Fedoraproject, Qemu, Redhat 5 Fedora, Qemu, Advanced Virtualization and 2 more 2026-11-05 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-2023-6683 2 Qemu, Redhat 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more 2026-11-05 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-2024-4467 1 Redhat 8 Advanced Virtualization, Container Native Virtualization, Enterprise Linux and 5 more 2026-11-04 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-2024-7409 1 Redhat 4 Advanced Virtualization, Enterprise Linux, Openshift and 1 more 2026-08-31 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-2021-35269 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2026-07-05 7.8 High
NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute from the MFT is setup in the function ntfs_attr_setup_flag, a heap buffer overflow can occur allowing for code execution and escalation of privileges.
CVE-2021-35268 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2026-07-05 6.7 Medium
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode is loaded in the function ntfs_inode_real_open, a heap buffer overflow can occur allowing for code execution and escalation of privileges.
CVE-2021-35267 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2026-07-05 7.8 High
NTFS-3G versions < 2021.8.22, a stack buffer overflow can occur when correcting differences in the MFT and MFTMirror allowing for code execution or escalation of privileges when setuid-root.
CVE-2021-35266 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2026-07-05 7.8 High
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution.

CVE-2025-47712 2 Nbdkit Project, Redhat 4 Nbdkit, Advanced Virtualization, Enterprise Linux and 1 more 2026-06-30 6.5 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 2 Nbdkit Project, Redhat 4 Nbdkit, Advanced Virtualization, Enterprise Linux and 1 more 2026-06-30 6.5 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.
