Detailsinfo

A vulnerability classified as very critical has been found in Pegatron Corp. Tdelo64.sys (affected version not known). Affected is some unknown functionality of the file Tdelo64.sys of the component IOCTL Dispatcher. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at kb.cert.org. This vulnerability is traded as CVE-2026-14961 since 07/07/2026. The exploitability is told to be easy. The attack needs to be approached locally.
