Name of the Vulnerable Software and Affected Versions: STMicroelectronics STM32F0 series devices (affected versions not specified)

Description: The issue is related to incorrect access control in RDP Level 1, which allows physically present attackers to extract the device's protected firmware via a special sequence of Serial Wire Debug (SWD) commands.
