| CVE-2024-8354 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-10-01 | N/A | 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-2024-6505 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-09-19 | N/A | 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-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2024-09-14 | N/A | 5.3 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 | 2 Qemu, Enterprise Linux | 2024-09-14 | N/A | 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 | 2 Qemu, Enterprise Linux | 2024-09-13 | N/A | 7.0 HIGH |
| 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-2023-3255 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2024-09-13 | N/A | 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-2023-3019 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-09-13 | N/A | 6.5 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-2017-8284 | 1 Qemu | 1 Qemu | 2024-08-05 | 6.9 MEDIUM | 7.0 HIGH |
| The disas_insn function in target/i386/translate.c in QEMU before 2.9.0, when TCG mode without hardware acceleration is used, does not limit the instruction size, which allows local users to gain privileges by creating a modified basic block that injects code into a setuid program, as demonstrated by procmail. NOTE: the vendor has stated "this bug does not violate any security guarantees QEMU makes. | |||||
| CVE-2019-20175 | 1 Qemu | 1 Qemu | 2024-08-05 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in ide_dma_cb() in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest system can crash the QEMU process in the host system via a special SCSI_IOCTL_SEND_COMMAND. It hits an assertion that implies that the size of successful DMA transfers there must be a multiple of 512 (the size of a sector). NOTE: a member of the QEMU security team disputes the significance of this issue because a "privileged guest user has many ways to cause similar DoS effect, without triggering this assert. | |||||
| CVE-2019-12929 | 1 Qemu | 1 Qemu | 2024-08-05 | 10.0 HIGH | 9.8 CRITICAL |
| The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue | |||||
| CVE-2019-12928 | 1 Qemu | 1 Qemu | 2024-08-05 | 10.0 HIGH | 9.8 CRITICAL |
| The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue | |||||
| CVE-2019-12247 | 1 Qemu | 1 Qemu | 2024-08-05 | 5.0 MEDIUM | 7.5 HIGH |
| QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable | |||||
| CVE-2020-24165 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-08-04 | N/A | 8.8 HIGH |
| An issue was discovered in TCG Accelerator in QEMU 4.2.0, allows local attackers to execute arbitrary code, escalate privileges, and cause a denial of service (DoS). Note: This is disputed as a bug and not a valid security issue by multiple third parties. | |||||
| CVE-2022-36648 | 1 Qemu | 1 Qemu | 2024-08-03 | N/A | 10.0 CRITICAL |
| The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS. Note: This has been disputed by multiple third parties as not a valid vulnerability due to the rocker device not falling within the virtualization use case. | |||||
| CVE-2022-35414 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-08-03 | 6.1 MEDIUM | 8.8 HIGH |
| softmmu/physmem.c in QEMU through 7.0.0 can perform an uninitialized read on the translate_fail path, leading to an io_readx or io_writex crash. NOTE: a third party states that the Non-virtualization Use Case in the qemu.org reference applies here, i.e., "Bugs affecting the non-virtualization use case are not considered security bugs at this time. | |||||
| CVE-2024-3567 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-06-10 | N/A | 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-2023-1544 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-04-19 | N/A | 6.3 MEDIUM |
| A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU. | |||||
| CVE-2023-0330 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-04-19 | N/A | 6.0 MEDIUM |
| A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem may lead to memory corruption bugs like stack overflow or use-after-free. | |||||
| CVE-2023-1386 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-04-17 | N/A | 7.8 HIGH |
| 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-2023-3354 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Enterprise Linux and 1 more | 2024-03-11 | N/A | 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. | |||||
