Full title: Linux OverlayFS Local Privilege Escalation Exploit 
Category: local exploits
Platform: linux
This Metasploit module exploit targets the Linux kernel bug in OverlayFS. A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.
