A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

do_change_type(): refuse to operate on unmounted/not ours mounts

Ensure that propagation settings can only be changed for mounts located in the caller's mount namespace. This change aligns permission checking with the rest of mount(2).
