From 0.2.0 until 0.2.5, PageantStream::new in pageant/src/wmmessage.rs trusts a peer-controlled four-byte length prefix and buffers until len + 4 bytes are available without checking the fixed _AGENT_MAX_MSGLEN transport capacity. An application that bridges an SSH forwarded-agent channel to the raw stream can allow a malicious server to force large allocations or retain a partially filled frame, causing client memory exhaustion. This issue is fixed in version 0.2.5.","state":0,"publishedAt":"2026-10-27T20:27:30.852+00:00","modifiedAt":"2026-10-27T20:27:30.852+00:00","affected":[{"ecosystem":"Vendor product","name":"russh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eugeny\",\n                    \"product\": \"russh\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.2.0, < 0.2.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/Eugeny/russh/security/advisories/GHSA-662x-8wvj-2276","https://github.com/Eugeny/russh/commit/69e4b55513eaa8ac9d2ad4236f13171fc164e10a","https://github.com/Eugeny/russh/releases/tag/v0.65.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116775","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116775","identifiers":["CVE-2026-116775"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
