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-2022-0358 [HIGH] CWE-273 GHSA-mv2v-9q68-4c8h: A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation
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.

A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.

CVE-2016-10208 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel
did not properly validate meta block groups. An attacker with physical
access could use this to specially craft an ext4 image that causes a denial
of service (system crash). (CVE-2016-10208)
It was discovered that an information disclosure vulnerability existed in
the ACPI implementation of the Linux kernel. A local attacker could use
this to expose sensitive information (kernel memory addresses).
(CVE-2017-11472)
It was discovered that a buffer overflow existed in the ACPI table parsing
implementation in the Linux kernel. A local attacker could use this to
construct a malicious ACPI table that, when loaded, cau

CVE-2018-13405 [HIGH] CWE-284 kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members
kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members
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.
A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux ker

CVE-2018-13405 kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members
The Linux kernel has a vulnerability in the fs/inode.c:inode_init_owner() function logic that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not.

The Security War in File Systems: An Empirical Study from A Vulnerability-Centric Perspective
## Abstract
This paper presents a systematic study on the security of modern file systems,
following a vulnerability-centric perspective. Specifically,
we collected 377 file system vulnerabilities committed to the CVE database in the past 20 years.
We characterize them from four dimensions that include why the vulnerabilities appear,
how the vulnerabilities can be exploited, what consequences can arise,
and how the vulnerabilities are fixed. This way, we build a deep understanding of
the attack surfaces faced by file systems, the threats imposed by the attack surfaces,
and the good and bad practices in mitigating the attacks in file systems. We envision that our study
will bring insights toward
