Anza Sounds the Alarm for Solana Validators on a Linux Bug Ubuntu Hasn’t Fixed

Anza warned Solana validators that Ubuntu has not yet shipped a patched kernel for CVE-2026-98432, a flaw that lets a remote attacker execute code on a server. AWS and Red Hat say the available workarounds do not fully protect against exploitation. A compromise of validator infrastructure could threaten network stability and staked SOL, so operators need to watch for a kernel fix and harden exposure in the meantime.
