This looks to me like you're copying the contents of an ELF binary from userspace memory into a kernel keyring, and then immediately copying it back from the kernel keyring to userspace memory, followed by userland exec the usual way. What's the point of the keyring steps, rather than just doing userland exec alone?

Can a process loaded this way be reverified once loaded?
