CVE-2025-48507
📋 TL;DR
This vulnerability in AMD Trusted Firmware (TF-A) fails to properly validate the security state of calling processors, potentially allowing non-secure processors to access secure memory regions, perform cryptographic operations, and control SOC subsystems. This affects systems using vulnerable AMD processors with TF-A firmware.
💻 Affected Systems
- AMD processors with Trusted Firmware (TF-A)
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of secure enclaves, extraction of encryption keys, unauthorized control of SOC subsystems, and potential firmware-level persistence.
Likely Case
Information disclosure from secure memory regions and unauthorized access to cryptographic operations.
If Mitigated
Limited impact if proper hardware isolation and firmware protections are in place.
🎯 Exploit Status
Exploitation requires deep understanding of AMD processor architecture and firmware internals
