Summary
Vulnerability reported (CVE-2026-14960). Successful exploitation can lead to full system takeover. Exploitable via Tdelo64.sys.
Original description
The description as published by the source.
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.
