CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:NSummary
CVE-2025-26305 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-2025-26305 is a memory leak vulnerability in the parseSWF_SOUNDINFO function within util/parser.c of libming version 0.4.8. This issue affects the libming library, which handles parsing of Macromedia Flash (SWF) files, and is classified under CWE-244 (Improper Clearing of Heap Memory Before Release). The vulnerability was published on 2025-02-20 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), highlighting its high severity due to network accessibility and low attack complexity.
Remote attackers require no privileges or user interaction to exploit this flaw by supplying a specially crafted SWF file to a vulnerable libming instance. Successful exploitation triggers the memory leak, enabling a denial of service through resource exhaustion, while the high confidentiality impact indicates potential leakage of sensitive information from heap memory and low integrity impact from possible memory corruption.
Mitigation details and further discussion are available in the GitHub issue at https://github.com/libming/libming/issues/322.

Explicitly requires secure deletion of sensitive data, directly addressing improper heap clearing.
Secure SDLC processes can incorporate memory-safety requirements but do not specifically mandate heap clearing.
Mandates secure coding practices that include proper memory sanitization before release.
Secure architecture principles may reduce exposure but do not prescribe explicit heap-clearing techniques.
