📋 Description
In src/havegecmd.c, the socket_handler function performs a credential check on the abstract UNIX socket (\0/sys/entropy/haveged). However, while it detects if the connecting user is not root (cred.uid != 0) and prepares a negative acknowledgement (ASCII_NAK), it fails to stop execution. The code proceeds to the switch statement, allowing any local unprivileged user to execute privileged commands such as MAGIC_CHROOT.
