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.
