Typical severity: Very High. Likelihood of attack: Medium. An adversary takes advantage of missing or incorrectly configured access control within memory to read/write data or inject malicious code into said memory.
Ensure that protected and unprotected memory ranges are isolated and do not overlap. | If memory regions must overlap, leverage memory priority schemes if memory regions can overlap. | Ensure that original and mirrored memory regions apply the same protections. | Ensure immutable code or data is programmed into ROM or write-once memory.
