Detailsinfo

A vulnerability classified as very critical was found in Pegatron Corp. Tdelo64.sys. Affected by this vulnerability is the function TDE_IOCTL_INDEXIO_READ/TDE_IOCTL_INDEXIO_WRITE of the file Tdelo64.sys of the component IOCTL Handler. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at kb.cert.org. This vulnerability is known as CVE-2026-14960 since 07/07/2026. The exploitation appears to be easy. An attack has to be approached locally.
