CVE-2026-14960

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.

Summary		(es) Pegatron ’Tdelo64.sys’ expone indebidamente la funcionalidad de acceso privilegiado al hardware a través de la interfaz de dispositivo ’\\.\TdeIo’. Los controladores IOCTL, incluyendo ’TDE_IOCTL_INDEXIO_READ’ y ’TDE_IOCTL_INDEXIO_WRITE’, permiten a los llamadores en modo de usuario sin privilegios realizar lecturas y escrituras arbitrarias en puertos de E/S de hardware sin comprobaciones de autorización. Un atacante local puede abusar de esta funcionalidad para manipular registros de hardware, alterar interfaces relacionadas con el firmware, causar inestabilidad en el sistema o establecer un compromiso persistente de bajo nivel.
