It’s not clear to me that the kernel allows the receiving process to write instead of just read. But also, if you are sending data, why would you later read/process that send buffer? The only attack vector I could imagine would be if one sender was splicing the same memory to two or more receivers. A malicious receiver with write access to the spliced memory could compromise other readers.
