CVE-2026-41054

SUSE Container suse/sle-micro-rancher/5.3:latest, Container suse/sle-micro-rancher/5.4:latest, Container suse/sle-micro/5.5:latest

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`.
