CVE-2026-35092 2 Corosync, Redhat 3 Corosync, Enterprise Linux, Openshift 2026-04-07 N/A 7.5 HIGH
A flaw was found in Corosync. An integer overflow vulnerability in Corosync's join message sanity validation allows a remote, unauthenticated attacker to send crafted User Datagram Protocol (UDP) packets. This can cause the service to crash, leading to a denial of service. This vulnerability specifically affects Corosync deployments configured to use totemudp/totemudpu mode.
CVE-2026-35091 2 Corosync, Redhat 3 Corosync, Enterprise Linux, Openshift 2026-04-07 N/A 8.2 HIGH
A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents. This vulnerability affects Corosync when running in totemudp/totemudpu mode, which is the default configuration.
