Summary

CVE-2025-31179 is a medium-severity NULL Pointer Dereference (CWE-476) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 6.2 (Medium).

Operationally, ranked at the 8th 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 SC-24 (Fail in Known State) and SI-11 (Error Handling) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SI-11 Error Handling good match
prevent

Directly requires graceful error handling for invalid conditions such as the NULL pointer dereference in xstrftime() that produces the segmentation fault.

SC-24 Fail in Known State good match
prevent

Ensures the system fails in a known, non-crashing state rather than terminating abruptly from the gnuplot NULL dereference flaw.

SI-17 Fail-safe Procedures partial match
prevent

Mandates fail-safe procedures that can contain or avoid the crash caused by the CWE-476 defect in xstrftime().

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices (static analysis, code review, safe coding standards) directly prevent NULL dereference bugs during development.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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

Security testing can detect NULL dereference defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify input validation and pointer-safety rules.

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

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
