Summary

CVE-2025-29044 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Netgear R6100 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 40% 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 SI-10 (Information Input Validation) — 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-2025-29044 is a buffer overflow vulnerability, tracked under CWE-120, that affects the Netgear R61 router running firmware version V1.0.1.28. The flaw resides in handling of the QUERY_STRING key value and permits uncontrolled memory operations that can corrupt adjacent stack data.

A remote attacker can exploit the issue over the network without authentication or user interaction by supplying a crafted QUERY_STRING parameter, resulting in arbitrary code execution with full control over the affected device. The vulnerability carries a CVSS 3.1 base score of 9.8, reflecting its critical severity and ease of remote exploitation.

Public references consist of proof-of-concept repositories and gists that demonstrate the stack overflow on related Netgear R6100 hardware; no vendor advisories, firmware patches, or official mitigation guidance appear among the listed sources. The EPSS score rose from a low baseline to a peak of 0.1149 on 2026-05-30 before receding to its current value of 0.0634, indicating measurable post-disclosure exploitation interest that warrants renewed monitoring.
