CVE-2019-14237
On NXP Kinetis KV1x, Kinetis KV3x, and Kinetis K8x devices, Flash Access Controls (FAC) (a software IP protection method for execute-only access) can be defeated by observing CPU registers and the effect of code/instruction execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
