    Package        : corosync     Version        : 3.1.2-2+deb11u1     CVE ID         : CVE-2025-30472


    An issue has been found in corosync, a cluster engine daemon and     utilities. A stack-based buffer overflow may happen when encryption is     disabled or the attacker knows the encryption key and a large crafted UDP     packet has to be processed.



    For Debian 11 bullseye, this problem has been fixed in version     3.1.2-2+deb11u1.

    We recommend that you upgrade your corosync packages.
