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.
