Exploitation Probability (EPSS)

Low risk
0.13%

2th percentile - higher than 2% of all known CVEs

Summary

Insufficient boundary validation in the USB boot mode implementation of AMD Zynq UltraScale+ MPSoC and RFSoC devices could allow unbounded Device Firmware Upgrade (DFU) download requests to overflow the DDR receive buffer into FSBL memory, potentially resulting in unauthorized code execution during the boot process.

Risk Assessment

This issue could impact the confidentiality, integrity, or availability of affected systems, allowing an attacker to execute code at a very early boot stage before the operating system loads.

Recommendation

Apply the available updates or mitigations provided by AMD for affected devices and restrict physical access to USB ports used in boot mode.
