| CVE-2024-2494 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2026-04-15 | 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-2024-4467 | 1 Redhat | 7 Advanced Virtualization, Container Native Virtualization, Enterprise Linux and 4 more | 2026-04-15 | 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-2024-3446 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2026-04-15 | 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-2025-8860 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Openshift | 2026-04-15 | 3.3 Low |
| A flaw was found in QEMU in the uefi-vars virtual device. When the guest writes to register UEFI_VARS_REG_BUFFER_SIZE, the .write callback `uefi_vars_write` is invoked. The function allocates a heap buffer without zeroing the memory, leaving the buffer filled with residual data from prior allocations. When the guest later reads from register UEFI_VARS_REG_PIO_BUFFER_TRANSFER, the .read callback `uefi_vars_read` returns leftover metadata or other sensitive process memory from the previously allocated buffer, leading to an information disclosure vulnerability. | ||||
| CVE-2024-8612 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2026-04-15 | 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-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2026-02-25 | 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 | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2026-02-25 | 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-2023-5088 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2026-02-25 | 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-2021-39261 | 3 Debian, Redhat, Tuxera | 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more | 2025-12-05 | 6.7 Medium |
| A crafted NTFS image can cause a heap-based buffer overflow in ntfs_compressed_pwrite in NTFS-3G < 2021.8.22. | ||||
| CVE-2021-33285 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Advanced Virtualization and 2 more | 2025-12-03 | 6.7 Medium |
| In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytes_in_use" field should be less than the "bytes_allocated" field. When it is not, the parsing of the records proceeds into the wild. | ||||

| A crafted NTFS image can cause an out-of-bounds access in ntfs_inode_sync_standard_information in NTFS-3G < 2021.8.22. | ||||
| CVE-2021-39259 | 3 Debian, Redhat, Tuxera | 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more | 2025-12-02 | 6.7 Medium |
| A crafted NTFS image can trigger an out-of-bounds access, caused by an unsanitized attribute length in ntfs_inode_lookup_by_name, in NTFS-3G < 2021.8.22. | ||||
| CVE-2021-39258 | 3 Debian, Redhat, Tuxera | 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more | 2025-12-02 | 6.7 Medium |

| A crafted NTFS image can trigger an out-of-bounds read, caused by an invalid attribute in ntfs_attr_find_in_attrdef, in NTFS-3G < 2021.8.22. | ||||
| CVE-2021-39254 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Advanced Virtualization and 2 more | 2025-12-02 | 6.7 Medium |
| A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in the function ntfs_attr_record_resize, in NTFS-3G < 2021.8.22. | ||||
