CVE-2024-8612 1 Redhat 2 Advanced Virtualization, Enterprise Linux 2025-11-08 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 2025-11-08 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-2023-5215 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Libnbd 2025-11-08 5.3 Medium
A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbd_get_size() function correctly.
CVE-2024-1441 1 Redhat 2 Advanced Virtualization, Enterprise Linux 2025-11-08 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-2024-8235 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Libvirt 2025-11-08 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-2024-6505 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2025-11-08 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-2024-4693 1 Redhat 2 Advanced Virtualization, Enterprise Linux 2025-11-08 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 3 Qemu, Advanced Virtualization, Enterprise Linux 2025-11-08 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 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more 2025-11-08 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-2023-3750 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Libvirt 2025-11-08 6.5 Medium
A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, resulting in a race condition and denial of service when attempting to lock the same object from another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt daemon.
CVE-2023-3255 3 Fedoraproject, Qemu, Redhat 4 Fedora, Qemu, Advanced Virtualization and 1 more 2025-11-08 6.5 Medium
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.
CVE-2024-3447 3 Netapp, Qemu, Redhat 4 Hci Compute Node, Qemu, Advanced Virtualization and 1 more 2025-11-03 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-2020-15890 4 Canonical, Debian, Luajit and 1 more 4 Ubuntu Linux, Debian Linux, Luajit and 1 more 2025-11-03 7.5 High
LuaJit through 2.1.0-beta3 has an out-of-bounds read because __gc handler frame traversal is mishandled.
