CWE-1262Improper Access Control for Register Interface
The product uses memory-mapped I/O registers that act as an interface to hardware functionality from software, but there is improper access control to those registers.
Software commonly accesses peripherals in a System-on-Chip (SoC) or other device through a memory-mapped register interface. Malicious software could tamper with any security-critical hardware data that is accessible directly or indirectly through the register interface, which could lead to a loss of confidentiality and integrity.

Answering this weakness across the control lifecycle, from our framework cross-walks.
NIST 800-53 r5 controls PROPOSED for this weakness (0)AI-assisted
These are model PROPOSALS, not graded mappings. They come
from controls_to_cwe_proposals, which carries no grade field at
all; across the CWE pages 1,540 of 1,722 such associations (89%) have never
been graded by anything. The heading said “address” until
2026-09-29, which asserted a relationship the data does not carry.
Graded cross-walks are on the framework map, not here.
