Summary

CVE-2024-42425 is a low-severity Access of Memory Location After End of Buffer (CWE-788) vulnerability in Dell Precision 7920 Firmware. Its CVSS base score is 3.8 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover buffer-end violations through static analysis, fuzzing, or dynamic bounds checks.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles require bounds checking, safe arithmetic, and language choices that structurally eliminate post-end buffer accesses.

SI-10 Information Input Validation partial match

Input validation enforces bounds on lengths and indices before buffer operations, stopping out-of-bounds accesses after the end of the buffer.

SI-16 Memory Protection partial match

Memory protection mechanisms limit the effects of post-end buffer accesses by blocking unauthorized code execution or data corruption.

PR.PS-06 mostly match
prevents

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

ID.RA-01 partial match
prevents

Vulnerability scanning and code analysis directly surface buffer-boundary flaws.

ID.RA-08 partial match
prevents

Receiving and triaging vulnerability disclosures commonly includes buffer-related reports.

PR.AT-02 partial match
prevents

Developer training on secure coding reduces introduction of memory-buffer errors.

PR.PS-02 partial match
prevents

Patching replaces vulnerable code containing buffer-boundary defects.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect buffer-overrun defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle includes buffer-handling practices that reduce out-of-bounds accesses.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate bounds checking and safe memory APIs.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe pointer arithmetic and unbounded buffers.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid writing or reading past buffer ends.
