| CVE-2021-3929 | 2 Fedoraproject, Qemu | 2 Fedora, Qemu | 2024-02-04 | N/A | 8.2 HIGH |
| A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host. | |||||
| CVE-2022-0358 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-02-04 | N/A | 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-2021-4158 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-02-04 | N/A | 6.0 MEDIUM |
