UBUNTU-CVE-2026-97032

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...

CVE-2026-78669

A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGSINITIALWINDOWSIZE values...

CVE-2026-94439

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server...

CVE-2026-78667

A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...

CVE-2026-97032

HTTP/2 servers are susceptible to a race condition (CWE-362) that can lead to a server crash. The vulnerability occurs because the HPACK encoder is modified concurrently from two different goroutines without proper synchronization: one goroutine encodes a HEADERS frame for a response, while anoth...

CVE-2026-97032

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...

CVE-2026-78663

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 can exploit this to bypass the configur...

CVE-2026-78660

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 headers to an HTTP/1 client when acting as a...

CVE-2026-78667

The FileServer(FS) , ServeContent , and ServeFile(FS) components are vulnerable to a CPU exhaustion issue. This occurs when parsing a Range header that contains a large number of small ranges, leading to excessive resource consumption. This vulnerability is associated with CWE-770 (Allocation of ...

CVE-2026-94439 HTTP/1 server connection desynchronization after 2xx CONNECT response in net/http

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server...

CVE-2026-78669

A malicious HTTP/2 peer can trigger excessive CPU consumption in a client or server by opening numerous streams and transmitting many small SETTINGS frames containing SETTINGS_INITIAL_WINDOW_SIZE values. This vulnerability impacts several packages, including loki , cloud-sql-proxy , kube-bench , ...
