Summary

CVE-2024-2398 is a high-severity Missing Release of Resource after Effective Lifetime (CWE-772) vulnerability in Apple Macos. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers for the push surpasses the maximum allowed limit (1000), libcurl aborts the server push. When aborting, libcurl inadvertently does not free all…

the previously allocated headers and instead leaks the memory. Further, this error condition fails silently and is therefore not easily detected by an application.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing resource releases through dynamic analysis or stress testing.

Requiring documented development standards and tools can mandate explicit resource-release patterns in code.

Resource-quota allocation limits the blast radius of an unreleased-resource exhaustion condition.

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.

ID.AM-08 mostly match
prevents

Lifecycle management explicitly requires handling resources through end-of-life including release.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent missing resource-release defects during development.

DE.CM-09 partial match
prevents

Runtime monitoring may surface resource-exhaustion symptoms but does not address release logic.

PR.IR-04 partial match
prevents

Capacity monitoring can detect exhaustion caused by unreleased resources but does not prevent the root defect.

degrades

Explicit information-deletion requirements directly address timely release of resources after use.

prevents

Secure-SDLC practices include resource-management reviews, yet the control covers the entire lifecycle, not just this weakness.

prevents

Secure-coding rules can mandate explicit resource-release patterns, but the control is broader than this single weakness.

detects

Change-management processes may catch missing de-allocation during reviews, but the control itself does not target resource lifetime.

none

Configuration baselines can enforce resource limits or timeouts, indirectly reducing exposure to leaks.
