CVE-2026-97032HTTP/2 server crash due to HPACK encoder race in net/http

Go standard library net/http; Go standard library net/http/internal/http2; golang.org/x/net golang.org/x/net/http2 Publicada: (hace 1 mes)

Descripción

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.

Debilidad (CWE): CWE-362

HTTP/2 transport accepts malformed framing-related headers in net/http

Go standard library net/http; Go standard library net/http/internal/http2; golang.org/x/net golang.org/x/net/http2

Historically, we have been rather lax about malformed framing-related headers in our HTTP/2 implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our HTTP/2 implementation to forward responses containing such header…

Double flow control refund on HTTP/2 server streams in net/http

Go standard library net/http; Go standard library net/http/internal/http2; golang.org/x/net golang.org/x/net/http2

The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream (refunding data for any sent-but-unread portion of the stream), and again when a request handler reads the buffered data. A malicious client…
