| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-35092 | 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. | [email protected] | 7.5 | 0.31% | 2026-04-01 | 2026-05-26 |
| CVE-2026-35091 | 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 | [email protected] | 8.2 | 0.24% | 2026-04-01 | 2026-05-26 |
| CVE-2025-30472 | 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. | [email protected] | 9.0 | 0.21% | 2025-03-22 | 2025-11-03 |
