{"id":"CVE-2026-103761","summary":"Mooncake transfer engine through 0.3.13.post1 Memory Exhaustion via Unbounded Notify Queue","details":"Mooncake transfer engine through 0.3.13.post1 contains a memory exhaustion vulnerability in TransferMetadata::receivePeerNotify that allows unauthenticated attackers to grow process memory without limit. Attackers can repeatedly send notify frames up to 1 MB to the handshake RPC port, filling the uncapped notifys vector until the out-of-memory killer terminates the engine.","modified":"2026-10-04T02:30:34.238539337Z","published":"2026-10-01T22:53:06.016Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103761.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/103xxx/CVE-2026-103761.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103761"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/mooncake-transfer-engine-through-0.3.13-post1-memory-exhaustion-via-unbounded-notify-queue"},{"type":"REPORT","url":"https://github.com/kvcache-ai/Mooncake/issues/4445"},{"type":"PACKAGE","url":"https://github.com/kvcache-ai/Mooncake"},{"type":"ARTICLE","url":"https://github.com/kvcache-ai/Mooncake/blob/719735896c86b56fabec6cf3e825fb2ea640597a/mooncake-transfer-engine/src/transfer_metadata.cpp#L285-L296"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kvcache-ai/mooncake","events":[{"introduced":"0"},{"fixed":"719735896c86b56fabec6cf3e825fb2ea640597a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.3.13.post1"},{"fixed":"0.3.13.post1"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v0.3.13-rc2","v0.3.13-rc1","v0.3.13","v0.3.12.post1","v0.3.11-rc1","v0.3.11.post1","v0.3.11","v0.3.10.post2","v0.3.10.post1","v0.3.10","v0.3.9","v0.3.8.post1","v0.3.8","v0.3.7.post2","v0.3.7.post1","v0.3.7","v0.3.6.post1","v0.3.6","v0.3.5","v0.3.4.post2","v0.3.4.post1","v0.3.4","v0.3.3.post2","v0.3.3.post1","v0.3.3","v0.3.2.post1","v0.3.2","v0.3.1","v0.3.0","v0.3.0-beta","v0.3.0-alpha","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-103761.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
