What is CVE-2026-14960?
CVE-2026-14960 is a critical vulnerability in Pegatron Corp. Tdelo64.sys, published on 15 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
