CVE-2026-14961

Description

Pegatron `Tdelo64.sys` exposes a privileged device interface, `\\.\TdeIo`, that fails to properly restrict access to sensitive IOCTL functionality. The driver's IOCTL dispatcher does not validate caller privileges or verify user-supplied kernel memory addresses before performing memory operations. By sending crafted requests to IOCTL, a local attacker can achieve arbitrary kernel memory read and write operations, leading to privilege escalation to `NT AUTHORITY\SYSTEM`, security product bypass, credential theft, or complete system compromise.
