CVE-2022-0358 is a high-severity flaw in QEMU's virtio-fs shared file system daemon, affecting QEMU and Red Hat Enterprise Linux. It allows a local guest user to create files with unintended group ownership in SGID directories, potentially leading to privilege escalation within the guest and on the host. With a CVSS score of 7.8, this vulnerability has a low attack complexity and can result in high impact to confidentiality, integrity, and availability. Currently, there is no known active exploitation, public exploit code, or significant community discussion surrounding this CVE.

CVE-2022-0358
Sep 10, 2024A 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.
