| CVE-2026-81665 | 2 Corosync, Redhat | 4 Corosync, Enterprise Linux, Openshift and 1 more | 2026-09-04 | 7.5 High |
| A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control. | ||||

| An integer overflow was found in Corosync's handling of membership commit token messages. The length-validation check for these messages can be bypassed on 32-bit systems due to an integer overflow in the calculation of the expected message length, allowing a crafted network packet to trigger an out-of-bounds memory access that crashes the Corosync daemon. This results in a denial of service for the affected cluster node. The overflow does not occur on 64-bit systems, where the length calculation is correctly performed in 64-bit arithmetic. | ||||
| CVE-2026-35091 | 2 Corosync, Redhat | 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-05-26 | 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 | ||||
| CVE-2026-35092 | 2 Corosync, Redhat | 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-05-26 | 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-2025-30472 | 2 Corosync, Redhat | 2 Corosync, Enterprise Linux | 2025-11-03 | 9 Critical |
| Corosync through 3.1.9, if encryption is disabled or the attacker knows the encryption key, has a stack-based buffer overflow in orf_token_endian_convert in exec/totemsrp.c via a large UDP packet. | ||||
| CVE-2013-0250 | 1 Corosync | 1 Corosync | 2025-04-12 | N/A |
| The init_nss_hash function in exec/totemcrypto.c in Corosync 2.0 before 2.3 does not properly initialize the HMAC key, which allows remote attackers to cause a denial of service (crash) via a crafted packet. | ||||
| CVE-2018-1084 | 4 Canonical, Corosync, Debian and 1 more | 5 Ubuntu Linux, Corosync, Debian Linux and 2 more | 2024-11-21 | 7.5 High |
| corosync before version 2.4.4 is vulnerable to an integer overflow in exec/totemcrypto.c. | ||||
