| CVE-2008-2382 | 2 Kvm Qumranet, Qemu | 2 Kvm, Qemu | 2026-04-23 | N/A |
| The protocol_client_msg function in vnc.c in the VNC server in (1) Qemu 0.9.1 and earlier and (2) KVM kvm-79 and earlier allows remote attackers to cause a denial of service (infinite loop) via a certain message. | ||||
| CVE-2007-6227 | 1 Qemu | 1 Qemu | 2026-04-23 | N/A |
| QEMU 0.9.0 allows local users of a Windows XP SP2 guest operating system to overwrite the TranslationBlock (code_gen_buffer) buffer, and probably have unspecified other impacts related to an "overflow," via certain Windows executable programs, as demonstrated by qemu-dos.com. | ||||
| CVE-2007-1322 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2026-04-23 | N/A |
| QEMU 0.8.2 allows local users to halt a virtual machine by executing the icebp instruction. | ||||
| CVE-2007-1321 | 5 Debian, Fedoraproject, Qemu and 2 more | 6 Debian Linux, Fedora, Fedora Core and 3 more | 2026-04-23 | N/A |
| Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730. | ||||
| CVE-2008-2004 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2026-04-23 | N/A |
| The drive_init function in QEMU 0.9.1 determines the format of a raw disk image based on the header, which allows local guest users to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted. | ||||
| CVE-2007-5730 | 4 Debian, Qemu, Redhat and 1 more | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2026-04-23 | N/A |
| Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability. | ||||
| CVE-2009-3616 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux Server, Enterprise Linux Workstation | 2026-04-23 | 9.9 Critical |
| Multiple use-after-free vulnerabilities in vnc.c in the VNC server in QEMU 0.10.6 and earlier might allow guest OS users to execute arbitrary code on the host OS by establishing a connection from a VNC client and then (1) disconnecting during data transfer, (2) sending a message using incorrect integer data types, or (3) using the Fuzzy Screen Mode protocol, related to double free vulnerabilities. | ||||
| CVE-2008-4553 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2026-04-23 | N/A |
| qemu-make-debian-root in qemu 0.9.1-5 on Debian GNU/Linux allows local users to overwrite arbitrary files via a symlink attack on temporary files and directories. | ||||
| CVE-2008-4539 | 4 Canonical, Debian, Kvm Qumranet and 1 more | 4 Ubuntu Linux, Debian Linux, Kvm and 1 more | 2026-04-23 | N/A |
| Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue exists because of an incorrect fix for CVE-2007-1320. | ||||
| CVE-2007-1366 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2026-04-23 | N/A |
| QEMU 0.8.2 allows local users to crash a virtual machine via the divisor operand to the aam instruction, as demonstrated by "aam 0x0," which triggers a divide-by-zero error. | ||||
| CVE-2008-0928 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2026-04-23 | N/A |
| Qemu 0.9.1 and earlier does not perform range checks for block device read or write requests, which allows guest host users with root privileges to access arbitrary memory and escape the virtual machine. | ||||
| CVE-2008-5714 | 1 Qemu | 1 Qemu | 2026-04-23 | N/A |
| Off-by-one error in monitor.c in Qemu 0.9.1 might make it easier for remote attackers to guess the VNC password, which is limited to seven characters where eight was intended. | ||||
| CVE-2007-5729 | 3 Debian, Opensuse, Qemu | 3 Debian Linux, Opensuse, Qemu | 2026-04-23 | N/A |
| The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability. | ||||
| CVE-2007-1320 | 6 Debian, Fedoraproject, Opensuse and 3 more | 7 Debian Linux, Fedora, Fedora Core and 4 more | 2026-04-23 | N/A |
| Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow. | ||||
| CVE-2008-1945 | 6 Canonical, Debian, Opensuse and 3 more | 10 Ubuntu Linux, Debian Linux, Opensuse and 7 more | 2026-04-23 | N/A |
| QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004. | ||||
| CVE-2026-3195 | 1 Qemu | 1 Qemu | 2026-03-03 | 7.4 High |
| A flaw was found in QEMU. When reading input audio in the virtio-snd device input callback, the `virtio_snd_pcm_in_cb` function did not check whether the iov could fit the data buffer, potentially leading to a heap out-of-bounds write. This issue exists due to an incomplete fix for CVE-2024-7730. | ||||
| 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-2023-3019 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2026-01-27 | 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. | ||||
