Summary
CVE-2026-5992 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Tenda F451 Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Compromise Infrastructure (T1584); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-5992 is a stack-based buffer overflow vulnerability affecting the Tenda F451 router firmware version 1.0.0.7. The issue resides in the fromP2pListFilter function within the /goform/P2pListFilter file, where manipulation of the "page" argument triggers the overflow. Associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow), it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
Remote attackers with low privileges can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation enables high-impact outcomes on confidentiality, integrity, and availability, including potential remote code execution via the buffer overflow.
Advisories referenced in VulDB entries (vuln/356546 and related CTI/submit pages) and a GitHub issue in Jimi-Lab/cve describe the vulnerability and note that the exploit has been publicly disclosed and may be utilized. The Tenda manufacturer's website (tenda.com.cn) is listed among references, though specific patch details are not detailed in the provided information.
The exploit's public disclosure increases the risk of active utilization against unpatched Tenda F451 devices.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and analysis can discover stack-buffer overflows before deployment.
Input validation directly stops untrusted data from exceeding stack buffer bounds.
Memory-protection mechanisms limit the ability to execute injected code after a stack overflow.
Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.
