CVE-2021-44225 is fixed in keepalived on 1 platform, first by keepalived 1:1.3.9-1ubuntu0.18.04.3, released November 25, 2021. It is not reported as exploited. Patch Radar priority: High.
The keepalived utility provides simple and robust facilities for load balancing and high availability. The load balancing framework relies on the well-known and widely used IP Virtual Server (IPVS) kernel module providing layer-4 (transport layer) load balancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage a load balanced server pool according to the health of the servers. Keepalived also implements the Virtual Router Redundancy Protocol (VRRPv2) to achieve high availability with director failover.
