Summary

CVE-2024-4853 is a low-severity Mismatched Memory Management Routines (CWE-762) vulnerability in Wireshark Wireshark. Its CVSS base score is 3.6 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 35th percentile by exploit likelihood (below the median); 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-8 Security and Privacy Engineering Principles partial match

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

SI-10 Information Input Validation partial match

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

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.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

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 bounds-checking and safe memory handling.

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.

A.8.32 Change management partial match
prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
