Answer in brief
CVE-2026-97032 records a Unknown severity vulnerability in HTTP/2 server crash due to HPACK encoder race in net/http. The current sources do not mark it as known exploited. The current feed maps golang.org/x/net/golang.org/x/net/http2 (generic), Go standard library/net/http (generic), Go standard library/net/http/internal/http2 (generic), golang.org/x/net (go) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
