fs/namei.c in the Linux kernel before 5.5 has a may_create_in_sticky use-after-free which allows local users to cause a denial of service (OOPS) or possibly obtain sensitive information from kernel memory aka CID-d0cb50185ae9. One attack vector may be an open system call for a UNIX domain socket if the socket is being moved to a new parent directory and its old parent directory is being removed.
