Weakness (CWE)
CWE-1310: Missing Ability to Patch ROM Code
Missing an ability to patch ROM code may leave a System or System-on-Chip (SoC) in a vulnerable state.
More detail
A System or System-on-Chip (SoC) that implements a boot process utilizing security mechanisms such as Root-of-Trust (RoT) typically starts by executing code from a Read-only-Memory (ROM) component.
How to prevent it (2 mitigations)
-
Architecture and Design, Implementation
Secure patch support to allow ROM code to be patched on the next boot.
-
Architecture and Design, Implementation
Support patches that can be programmed in-field or during manufacturing through hardware fuses. This feature can be used for limited patching of devices after shipping, or for the next batch of silicon devices manufactured, without changing the full device ROM.
