Summary

CVE-2024-10396 is a medium-severity Missing Release of Resource after Effective Lifetime (CWE-772) vulnerability in Openafs Openafs. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked at the 45th 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 SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

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.
