SYSTEM privilege escalation via permissive kernel driver
Published May 12, 2026 · Updated May 12, 2026
Local privilege escalation in Fuji Electric TELLUS 5.0.2 allows local users to gain SYSTEM privileges through an exposed kernel driver. CISA does not identify the driver or its exposed interface, but reports that its permissions allow every user to read from and write to it. A low-privileged Windows account is required; successful exploitation enables file access or deletion and a temporary service interruption.
