prctl(PR_SET_DUMPABLE, 1, ...) is called unconditionally without a boolean guard. In privilege-separated (setuid) architectures where the calling process still holds a privileged IPC channel to a root parent, an attacker sharing the same UID can ptrace-attach to this now-dumpable process and inject arbitrary privileged operations through that channel.
