Summary

CVE-2025-24126 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Apple Ipados. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Exhaustion Flood (T1499.001); ranked in the top 31% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-24126 is an input validation vulnerability affecting multiple Apple operating systems, including iOS prior to 18.3, iPadOS prior to 18.3, macOS Sequoia prior to 15.3, macOS Sonoma prior to 14.7.5, macOS Ventura prior to 13.7.5, tvOS prior to 18.3, and visionOS prior to 2.3. The flaw allows an attacker on the local network to corrupt process memory, as indicated by its CVSS v3.1 base score of 7.3 (AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H) and association with CWE-400 (Uncontrolled Resource Consumption).

An attacker with low privileges on the local network can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation enables corruption of process memory, resulting in high integrity and availability impacts but no confidentiality loss, potentially leading to denial-of-service conditions or unauthorized modification of system processes.

Apple security advisories detail the fix through updates to the listed versions, recommending users apply patches immediately via standard update mechanisms.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-5 directly limits the effects of resource-exhaustion events that constitute uncontrolled consumption.

SC-6 enforces explicit allocation limits on resources, structurally preventing the weakness from occurring.

Process isolation confines resource consumption to separate domains, reducing blast radius without stopping the root flaw.

PR.IR-04 mostly match
prevents

Explicitly requires monitoring and maintaining resource capacity, directly addressing uncontrolled consumption to preserve availability.

DE.CM-09 partial match
prevents

Continuous monitoring of computing resources can detect resource exhaustion but does not itself enforce allocation limits.

PR.IR-03 partial match
prevents

Resilience mechanisms such as avoiding single points of failure indirectly reduce impact of resource exhaustion.

PR.PS-01 partial match
prevents

Hardened configuration baselines can include resource quotas and limits that constrain consumption.

finds

Resource-utilization monitoring and alerting on bottlenecks or overloads limits the impact of denial-of-service or resource-exhaustion attacks.

prevents

By continuously monitoring utilization, stress-testing peak loads, and maintaining documented plans to scale or throttle resources, the control directly limits an attacker’s ability to drive a system into uncontrolled resource exhaustion.

finds

Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.

mitigates

Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.

mitigates

Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.

finds

Early notification of anomalous resource consumption or system malfunctions enables throttling or isolation before availability is lost.
