How to fix?

Upgrade Debian:unstable nodejs to version 22.22.0+dfsg+~cs22.19.6-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs package and not the nodejs package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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 service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example:

server.on(&#39;secureConnection&#39;, socket =&gt; {
  socket.on(&#39;error&#39;, err =&gt; {
    console.log(err)
  })
})
