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.
