The simple_set_acl function in fs/posix_acl.c in the Linux kernel before
4.9.6 preserves the setgid bit during a setxattr call involving a tmpfs
filesystem, which allows local users to gain group privileges by leveraging
the existence of a setgid program with restrictions on execute permissions.
NOTE: this vulnerability exists because of an incomplete fix for
CVE-2016-7097.
