Summary
CVE-2023-38570 is a medium-severity Access of Memory Location After End of Buffer (CWE-788) vulnerability in Intel Unison Software. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

Secure SDLC practices directly require bounds checking and input validation that prevent out-of-bounds buffer accesses.

A.8.25 mandates secure SDLC practices (secure coding guidelines, security requirements, checkpoints, testing including code scans and penetration tests, developer training) that reach buffer management and can stop many out-of-bounds accesses from reaching production, but leaves a bounded remainder (e.g. defects that slip past imperfect testing, non-software systems, or outsourced development without full assurance).
A.8.26 explicitly lists resilience against buffer overflow (and SQLi) as one of the application security requirements to identify/address during development or acquisition; well-implemented, this reaches a minority slice of CWE-788 instances (those caught in requirements/risk assessment) but leaves most implementation-level buffer errors untouched.
A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, fail securely, distrust external input, hardening, zero-trust verification) plus design reviews against known attack patterns, which can stop buffer overruns from being exploitable in many cases but leaves a bounded remainder (e.g. unsafe legacy code, unsafe third-party libraries, or implementation errors that slip past reviews).
Secure coding standards directly forbid writing or reading past buffer ends.
Security testing in development can detect buffer-overrun defects before release.
