Summary

CVE-2026-0280 is a low-severity Incorrect Calculation of Buffer Size (CWE-131) vulnerability in Paloaltonetworks Pan-Os. Its CVSS base score is 1.7 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 24th 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

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer security testing and code review can discover incorrect buffer-size computations before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles directly require correct buffer-size arithmetic and bounds-checked allocation.

SI-10 Information Input Validation partial match

Input validation can enforce that supplied lengths or counts used in size calculations are within safe bounds.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability of an overflow that results from an incorrect size calculation.

SI-2 Flaw Remediation partial match

Flaw-remediation processes that include vulnerability scanning or static analysis will surface buffer-size errors.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent buffer-size miscalculations via coding standards, reviews, and testing, while fixing this single weakness only partially fulfills the broader control.

A.8.28 Secure coding mostly match
degrades

Secure coding standards directly require correct buffer-size calculations.

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

Security testing can detect buffer-size errors before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates size-checking practices that reduce buffer-size miscalculations.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify buffer-size validation rules.

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

Secure architecture principles include safe memory-allocation guidelines.
