{"id":"CVE-2026-97032","published":"2026-10-08T23:17:06.213","lastModified":"2026-10-09T16:35:35.900","description":"HTTP/2 servers could end up crashing due to inadvertently modifying its HPACK encoder concurrently. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://go.dev/cl/847188","tags":[]},{"url":"https://go.dev/cl/847313","tags":[]},{"url":"https://go.dev/issue/81867","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/U2fTuyDJznI","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/ZPwCyRUuGBs","tags":[]},{"url":"https://pkg.go.dev/vuln/GO-2026-6617","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
