A critical Linux vulnerability known as CopyFail, tracked as CVE-2026-31431, allows attackers to gain root access on systems running kernels since 2017. Publicly released exploit code has heightened risks for data centers and personal devices. Ubuntu's infrastructure has been offline for over a day due to a DDoS attack, hampering security communications.
Ubuntu's official Twitter account posted a now-deleted tweet promoting a fake AI agent that directed users to a cryptocurrency scam. The incident follows a five-day DDoS attack on Canonical's web services that ended earlier this month.
