Summary

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

CVE-2026-35091 (GCVE-0-2026-35091)

Vulnerability from cvelistv5 – Published: 2026-04-01 13:18 – Updated: 2026-05-29 16:21

Title

Corosync: corosync: denial of service and information disclosure via crafted udp packet

Summary

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

Severity

8.2 (High)
