I've been an avid Ubuntu user for years, but changed my mind and uninstalled it on every computer I own last weekend.

https://ubuntu.com/security/CVE-2026-98432#status

A one liner command then reboot: sudo sh -c 'echo "net.mptcp.enabled=0" > /etc/sysctl.d/99-disable-mptcp.conf && sysctl --system'

People actually use Ubuntu?
