In particular it can be used to change existing code mappings to be writable. Description.

mprotect() changes the access protections for the calling process's memory pages containing any part of the address range in the interval [addr, addr+len-1]. addr must be aligned to a page boundary. If the If the key allocation fails due to lack of support for memory protection keys, the pkey_mprotect call can usually be skipped.
