CVSS 7.5 HIGH
Record from redhat · Published October 6, 2026
A flaw was found in the HTTP/2 protocol implementation within the Go standard library (golang.org/x/net and net/http/internal/http2). A remote attacker can exploit this vulnerability by sending a specially crafted HTTP/2 SETTINGS frame with the SETTINGS_MAX_FRAME_SIZE parameter set to zero. This malicious frame causes the transport layer to enter an infinite loop of writing CONTINUATION frames, leading to resource exhaustion and a Denial of Service (DoS) condition.
