PR.PS-06 mostly match
prevents

Secure development practices directly prevent introduction of buffer over-read weaknesses.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover buffer over-read flaws via scanning or review.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software removes known instances of buffer over-read bugs.

detects

Security testing in development can detect buffer over-reads before release.

A.8.15 Logging partial match
detects

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure SDLC mandates input validation and bounds checking that can prevent buffer over-reads.

prevents

Application security requirements can specify buffer-size and bounds-checking rules.

prevents

Secure architecture principles include memory-safety and bounds-checking design choices.

prevents

Secure coding standards directly require bounds-checked buffer access, mitigating over-reads.
