CVE-2026-14961
6.2
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
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.
