Vulnerability from github – Published: 2026-07-15 18:31 – Updated: 2026-07-16 18:31

Details

Pegatron Tdelo64.sys improperly exposes privileged hardware access functionality through the \\.\TdeIo device interface. IOCTL handlers including TDE_IOCTL_INDEXIO_READ and TDE_IOCTL_INDEXIO_WRITE permit unprivileged user-mode callers to perform arbitrary hardware I/O port reads and writes without authorization checks. A local attacker can abuse this functionality to manipulate hardware registers, tamper with firmware-related interfaces, cause system instability, or establish persistent low-level compromise.

Severity

9.8 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
