Technical details

A stack-based buffer overflow exists in Altera Trusted Firmware's HPS (Hard Processor System) component due to improperly configured memory protections. The vulnerability allows an attacker with local or adjacent access to write beyond stack boundaries and potentially execute arbitrary code with firmware-level privileges. A patch or updated firmware version is required to remediate this issue.
