| CVE-2022-26353 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 7.5 High |
| A flaw was found in the virtio-net device of QEMU. This flaw was inadvertently introduced with the fix for CVE-2021-3748, which forgot to unmap the cached virtqueue elements on error, leading to memory leakage and other unexpected results. Affected QEMU version: 6.2.0. | ||||
| CVE-2022-1050 | 1 Qemu | 1 Qemu | 2024-11-21 | 8.8 High |
| A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition. | ||||
| CVE-2022-0358 | 2 Qemu, Redhat | 4 Qemu, Advanced Virtualization, Enterprise Linux and 1 more | 2024-11-21 | 7.8 High |
| A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of the group. This could allow a malicious unprivileged user inside the guest to gain access to resources accessible to the root group, potentially escalating their privileges within the guest. A malicious local user in the host might also leverage this unexpected executable file created by the guest to escalate their privileges on the host system. | ||||
| CVE-2022-0216 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-11-21 | 4.4 Medium |
| A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service. | ||||
| CVE-2021-4207 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 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. | ||||
