| CVE-2025-47711 | Med | 0.42 | 6.5 | 0.00 | Jun 9, 2025 | 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… | ||
| CVE-2023-6683 | Med | 0.42 | 6.5 | 0.01 | Jan 12, 2024 | 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.… | ||
| CVE-2023-5088 | Med | 0.42 | 6.4 | 0.00 | Nov 3, 2023 | 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… | ||
| CVE-2023-3255 | Med | 0.42 | 6.5 | 0.02 | Sep 13, 2023 | 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… | ||
| CVE-2023-3750 | Med | 0.42 | 6.5 | 0.01 | Jul 24, 2023 | 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… | ||
| CVE-2023-4135 | Med | 0.39 | 6.0 | 0.00 | Aug 4, 2023 | 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… | ||
| CVE-2023-3019 | Med | 0.39 | 6.0 | 0.00 | Jul 24, 2023 | 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-2023-5215 | Med | 0.35 | 5.3 | 0.01 | Sep 28, 2023 | 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… | ||
| CVE-2023-6693 | Med | 0.32 | 4.9 | 0.00 | Jan 2, 2024 | 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… |
