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 LSASS Memory (T1003.001); 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.

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

SA-11 Developer Testing and Evaluation good match

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

SA-15 Development Process, Standards, and Tools partial match

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

SC-6 Resource Availability partial match

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.

DE.CM-09 partial match
blocks

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

ID.AM-08 partial match
blocks

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

PR.IR-04 partial match
blocks

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

PR.PS-06 partial match
blocks

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