Summary

CVE-2024-2955 is a high-severity Mismatched Memory Management Routines (CWE-762) vulnerability in Wireshark Wireshark. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 30% 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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover mismatched memory calls through static analysis, dynamic testing, or fuzzing.

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

Documented development standards and tools can enforce or check for correct pairing of allocators and deallocators.

SA-3 System Development Life Cycle partial match

An SDLC that incorporates security can embed memory-safety requirements, reducing the chance such coding errors are introduced.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can mandate consistent use of matching allocation and deallocation routines during design and implementation.

Mitigating Controls (NIST CSF 2.0) AI

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.PS-06 mostly match
prevents

Secure SDLC practices directly prevent mismatched alloc/free via code review and static analysis, but fixing this single CWE only partially fulfills the broad control.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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

Security testing in development can detect mismatched alloc/free pairs before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates consistent allocation/deallocation patterns that prevent mismatched memory routines.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify correct use of release functions and pointer validation.

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

Secure system architecture and engineering principles require use of matching allocators and deallocators.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit mismatched memory-management calls and enforce safe patterns.
