It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-050 advisory.

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an 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 that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - 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-2022-0358)
