At the end of April 2026, the Linux community started talking about a flaw in the algif_aead kernel module. The issue is local, but critical: an attacker with minimal privileges inside the system can escalate to root. In practice, this means losing control over the server. After obtaining root access, a third-party user can extract databases, configuration files, SSH keys, or completely rebuild the system for their own purposes. The situation became much more dangerous because ready-made instructions and exploitation tools appeared in public access almost at the same time as the vulnerability itself became known. Script kiddies and automated scanners usually start using things like this within the first days.
