| CVE-2023-3019 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2025-11-06 | 6 Medium |
| A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. | ||||
| CVE-2025-12464 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Openshift | 2025-11-05 | 6.2 Medium |
| A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in 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-2024-7409 | 1 Redhat | 4 Advanced Virtualization, Enterprise Linux, Openshift and 1 more | 2025-11-03 | 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-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. | ||||
| CVE-2025-11234 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Openshift | 2025-10-10 | 7.5 High |
| A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication. | ||||
| CVE-2024-6519 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-08-08 | 8.2 High |
| A use-after-free vulnerability was found in the QEMU LSI53C895A SCSI Host Bus Adapter emulation. This issue can lead to a crash or VM escape. | ||||
| CVE-2024-7730 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-08-05 | 7.4 High |
| 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-2024-3446 | 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-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. | ||||
| CVE-2021-4206 | 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. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. | ||||
| CVE-2023-3354 | 3 Fedoraproject, Qemu, Redhat | 10 Fedora, Qemu, Advanced Virtualization and 7 more | 2025-02-13 | 7.5 High |
| 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. | ||||
| CVE-2023-3301 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2025-02-13 | 5.6 Medium |
| 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-2023-2680 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2025-02-13 | 7.5 High |
| This CVE exists because of an incomplete fix for CVE-2021-3750. More specifically, the qemu-kvm package as released for Red Hat Enterprise Linux 9.1 via RHSA-2022:7967 included a version of qemu-kvm that was actually missing the fix for CVE-2021-3750. | ||||
| CVE-2021-3667 | 3 Debian, Netapp, Redhat | 5 Debian Linux, Ontap Select Deploy Administration Utility, Advanced Virtualization and 2 more | 2025-02-13 | 6.5 Medium |
| An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occurs in the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly released on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock and prevent other users from accessing storage pool/volume APIs, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2023-4135 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 6 Medium |
| 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-2023-3180 | 4 Debian, Fedoraproject, Qemu and 1 more | 5 Debian Linux, Fedora, Qemu and 2 more | 2024-11-21 | 6 Medium |
| A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when the two values differ. | ||||
| CVE-2023-1386 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 3.3 Low |
| 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-2022-26354 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 3.2 Low |
| A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results. Affected QEMU versions <= 6.2.0. | ||||
