Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2025-48507. PoCs published by jdbonfils.

AI-analyzed exploit summary This repository contains a functional proof-of-concept exploit for CVE-2025-48507 and CVE-2025-0038, which allows non-secure software to bypass TrustZone isolation on Zynq UltraScale+ MPSoCs by manipulating SD Host Controller registers to gain read/write access to secure memory.

Description

The security state of the calling processor into Trusted Firmware (TF-A) is not used and could potentially allow non-secure processors access to secure memories, access to crypto operations, and the ability to turn on and off subsystems within the SOC.
