For anybody assessing risk from CVE-2026-98432, this is good from @malwaretech

tl;dr is basically likely a few million devices are vulnerable, some scanning, no sign of exploitation and no exploits available, development likely in the realms of nation state.

My POV - don't panic, calmly patch.

CVE-2026-98432 means that setting

net.mptcp.enabled = 0

in /etc/sysctl.conf is a very good idea. Then reboot to quash any existing sockets.

I'm not trying to rush you or anything, #Ubuntu, but could we maybe get a patch sometime this month?

#CVE-2026-58115 #security

Attackers exploit critical Node-RED flaw to deploy Linux bot and backdoors (CVE-2026-58115)

Attackers are exploiting an authentication flaw in Node-RED, CVE-2026-58115, to install a Linux bot and backdoors on unprotected servers, Help Net Security reports. VulnCheck found the attacks; Node-RED is a flow-based programming tool built on Node.js, built into some industrial control products and used in manufacturing, healthcare and home automation. https://www.helpnetsecurity.com/2026/11/03/node-red-cve-2026-58115-exploitation/

A VulnCheck canary has caught the first live exploitation of CVE-2026-58115, an unauthenticated Node-RED admin API flaw with a CVSS score of 10. One HTTP request wires an inject node to an exec node, and the flow downloads and runs a Linux bot. VulnCheck has logged 16 events from one source address.

How many Node-RED instances are still reachable without adminAuth?
