Summary

CVE-2025-29491 is a medium-severity Memory Allocation with Excessive Size Value (CWE-789) vulnerability in Libming Libming. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 25th 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 SI-10 (Information Input Validation) and SC-6 (Resource Availability) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly rejects or bounds untrusted size values before any allocation occurs.

SC-6 Resource Availability partial match

Resource quotas and priority allocation limit the system-wide impact of an oversized request.

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 coding flaws that trust unvalidated size values for allocations.

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 and block excessive allocation flaws before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and size checks that prevent unbounded allocations.

A.8.26 Application security requirements partial match
prevents

Application security requirements mandate bounds checking on size parameters to avoid excessive memory allocation.

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

Secure architecture principles require resource-limit enforcement that mitigates uncontrolled memory requests.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit allocating memory from untrusted size values without validation.

A.8.6 Capacity management none match
none

Capacity management monitors overall resource use but does not prevent individual allocation bugs.
