Summary

CVE-2026-92550 is a high-severity Memory Allocation with Excessive Size Value (CWE-789) vulnerability in Apache Qpid Broker-J (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 28th 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-6 (Resource Availability) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-6 Resource Availability partial match

Resource quotas and priority allocation limit the system-wide impact of an oversized request.

SI-10 Information Input Validation partial match

Input validation directly rejects or bounds untrusted size values before any allocation occurs.

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 partial match
prevents

Secure SDLC practices directly prevent coding flaws that trust unvalidated size values for allocations.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and size checks that prevent unbounded allocations.

A.8.26 Application security requirements partial match
prevents

Application security requirements mandate bounds checking on size parameters to avoid excessive memory allocation.

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

Secure architecture principles require resource-limit enforcement that mitigates uncontrolled memory requests.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit allocating memory from untrusted size values without validation.

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

Security testing in development can detect and block excessive allocation flaws before deployment.
