Summary

CVE-2025-26304 is a high-severity Heap Inspection (CWE-244) vulnerability in Libming Libming. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 31th 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 SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-26304 is a memory leak vulnerability identified in the parseSWF_EXPORTASSETS function within util/parser.c of libming version 0.4.8. This issue, published on 2025-02-20, is classified under CWE-244 and carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high severity primarily due to its potential for information disclosure.

Remote attackers can exploit this vulnerability over the network with low complexity, requiring no privileges or user interaction. Successful exploitation allows attackers to achieve high-impact confidentiality loss through memory leakage, alongside low-impact integrity modification, without affecting availability or changing the scope of impact.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-4 requires mechanisms that stop unintended transfer of sensitive data through shared resources such as heap memory reused after realloc.

PR.DS-10 mostly match
prevents

Explicit example of removing confidential data from process memory directly prevents heap inspection exposure.

PR.PS-06 partial match
prevents

Secure SDLC practices encompass proper sensitive-memory handling but fixing this single CWE does not achieve the control.

prevents

Explicitly requires secure deletion of sensitive data, directly addressing improper heap clearing.

prevents

Secure SDLC processes can incorporate memory-safety requirements but do not specifically mandate heap clearing.

prevents

Mandates secure coding practices that include proper memory sanitization before release.

none

Secure architecture principles may reduce exposure but do not prescribe explicit heap-clearing techniques.
