CVE-2019-14238
On STMicroelectronics STM32F7 devices, Proprietary Code Read Out Protection (PCROP) (a software IP protection method) can be defeated with a debug probe via the Instruction Tightly Coupled Memory (ITCM) bus.
Does this matter?
Lower severity and a low EPSS score (0.40%). Track it; it rarely justifies an emergency change on its own.
