Summary

CVE-2026-114595 is a critical-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Cisa (inferred from references). Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 43th 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.

Vulnerability Data

In EPICS Base release 7.0.10 and prior, an integer overflow in network request processing can cause memory to be allocated with an incorrect size. Subsequent handling of attacker supplied data may result in memory corruption, denial of service, or potential…

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation partial match

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

SI-10 Information Input Validation partial match

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

PR.PS-06 mostly match

Secure SDLC practices directly require use of safe arithmetic, bounds checks, and testing that prevent integer overflows.

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

Security testing in development can detect integer overflows before release.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.

A.8.8 Management of technical vulnerabilities partial match
finds

A.8.8's reach is DISCLOSURE — it identifies vulnerabilities through vendor advisories, vulnerability scanning, and third-party component tracking. Integer overflows in third-party components with published CVEs are found (the observed examples include several), but the bulk of CWE-190 instances in first-party/custom code are not what A.8.8 reaches; those require source-reading testing (A.8.28/A.8.29). Same logic as the A.8.8 finds CWE-89 = partial anchor.
