What is CVE-2026-14961?
CVE-2026-14961 is a medium-severity vulnerability in Pegatron Corp. Tdelo64.sys, published on 15 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
