CVE-2026-14960

Pegatron Corp. Tdelo64.sysVulnerabilityCVSS 9.8

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.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
