nodejs: Nodejs denial of service

A denial of service flaw has been discovered in NodeJS. A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of...

CVE-2026-21714

A flaw was found in Node.js. A remote attacker can exploit this vulnerability in Node.js HTTP/2 servers by sending specially crafted WINDOWUPDATE frames on stream 0 connection-level. These frames can cause the flow control window to exceed its maximum value, leading to a memory leak as Http2Sessi...

curl: HTTP/2 PUSH_PROMISE header loss on OOM bypasses scheme validation (regression of 2e8c922a89)

Summary: In lib/http2.c:1490, when curlmaprintf fails due to memory pressure, the push promise header is silently dropped but the callback returns success. If the lost header is the :scheme pseudo-header, the security check at line 733 that blocks HTTPS pushes over insecure connections is skipped...
