Summary

CVE-2025-20103 is a medium-severity Insufficient Resource Pool (CWE-410) vulnerability in Intel (inferred from references). Its CVSS base score is 5.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); 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 SC-6 (Resource Availability) and AC-10 (Concurrent Session Control) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SC-6 Resource Availability good match

SC-6 directly requires allocation of resources by priority or other means to protect availability against demand spikes.

AC-10 Concurrent Session Control partial match

AC-10 limits concurrent sessions per user, structurally capping how much of the pool any single actor can consume.

SC-5 Denial-of-service Protection partial match

SC-5 reduces the impact of resource-exhaustion DoS events without addressing pool sizing itself.

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.IR-04 full match
prevents

Directly requires maintaining adequate resource capacity to ensure availability, which prevents exhaustion attacks from insufficient pools.

A.8.6 Capacity management full match
degrades

Capacity management directly addresses sizing resource pools to handle peak demand and prevent exhaustion.

A.8.14 Redundancy of information processing facilities partial match
mitigates

Redundancy of processing facilities mitigates resource exhaustion by providing failover capacity.

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

Secure architecture principles include designing adequate resource allocation and limits.

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

Security testing can detect insufficient resource pools before deployment.
