This happens because the server modifies the HPACK encoder from two goroutines without synchronization: one uses the encoder to encode a HEADERS frame as part of a response sent to a client and the other modifies the encoder's table size when handling a SETTINGS frame containing SETTINGS_HEADER_TABLE_SIZE that a client sends. A malicious client can repeatedly send a request while changing the header table size to crash the server.","state":0,"publishedAt":"2026-10-08T23:17:06.213+00:00","modifiedAt":"2026-10-15T16:18:24.967+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · 134c704f-9b21-4f2e-91b3-4a467353bcc0 · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://go.dev/cl/847188","https://go.dev/cl/847313","https://go.dev/issue/81867","https://groups.google.com/g/golang-announce/c/U2fTuyDJznI","https://groups.google.com/g/golang-announce/c/ZPwCyRUuGBs","https://pkg.go.dev/vuln/GO-2026-6617"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-97032","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-362"],"productCriteria":[],"sourceDates":{"published":"2026-10-08T23:17:06.213","lastModified":"2026-10-15T16:18:24.967"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
