UBUNTU-CVE-2026-41054

In src/havegecmd.c, the sockethandler 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 ASCIINAK, it fails to stop execution. The code proceeds...
