Prior to 0.63.1, a connection configured to permit mac=none can negotiate it with a MAC-requiring CTR or CBC block cipher because the selection logic validates needs_mac() only when MAC selection fails. A remote peer can then send a packet with a decrypted length of zero, causing russh/src/cipher/mod.rs to shrink the previously read block before indexing buffer.buffer[16..], which panics and terminates the connection task. This issue is fixed in version 0.63.1.","evidence":"cve:CVE-2026-102822","products":[{"name":{"value":"russh","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"low","structured":{"id":"CVE-2026-102822","aliases":["CVE-2026-102822"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":3.7,"attackVector":"NETWORK","baseSeverity":"LOW","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"LOW","privilegesRequired":"NONE","confidentialityImpact":"NONE"}}],"affected":[{"vendor":"Eugeny","product":"russh","versions":[{"status":"affected","version":"< 0.63.1"}]}],"modified":"2026-09-29T19:53:30.291Z","provider":"cve","references":["https://github.com/Eugeny/russh/security/advisories/GHSA-p8qx-h547-fjw9","https://github.com/Eugeny/russh/commit/2885385abfee279092a41d80c6cb6ac367353159","https://github.com/Eugeny/russh/releases/tag/v0.63.1"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102822","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T19:53:03.923621Z"}}}],"references":[{"url":"https://github.com/Eugeny/russh/security/advisories/GHSA-p8qx-h547-fjw9","tags":["exploit"]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T19:53:30.291Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-29T18:23:28.061Z"}}},"related_cves":[{"value":"CVE-2026-102822","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3996,"next_before":3996}
