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

CVE-2025-25522 is a buffer overflow vulnerability (CWE-120) in the Linksys WAP610N wireless access point running firmware version 1.0.05.002. The issue stems from a lack of length verification in the time setting operation, allowing overflow conditions that can be exploited. Published on 2025-02-11, it has a CVSS v3.1 base score of 7.3 (AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L), indicating high integrity impact potential with low confidentiality and availability effects.

A local attacker with no privileges or user interaction required can exploit this vulnerability due to its low attack complexity. Successful exploitation enables the attacker to directly control the remote target device, potentially leading to unauthorized modifications or further compromise.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and analysis can find missing size checks before deployment.

SI-10 Information Input Validation good match

Input validation directly enforces size checks before buffer copies.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles require bounds checking and safe buffer handling in design.

SI-16 Memory Protection partial match

Memory protection limits the impact of an overflow once it occurs.

A.8.28 Secure coding mostly match
prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

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

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
