CVE-2026-2927
Published: 22 February 2026
Summary
CVE-2026-2927 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Dlink Dwr-M960 Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46.0th 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-2927 is a stack-based buffer overflow vulnerability affecting the D-Link DWR-M960 router running firmware version 1.01.07. The issue resides in the function sub_462590 within the file /boafrm/formOpMode of the Operation Mode Configuration Endpoint. It is triggered by manipulating the submit-url argument, and is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow). The vulnerability 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), indicating high severity.
The vulnerability can be exploited remotely by an attacker with low privileges, such as an authenticated user, requiring low attack complexity and no user interaction. Successful exploitation allows the attacker to achieve high impacts on confidentiality, integrity, and availability, potentially leading to full compromise of the affected device. An exploit has been publicly disclosed and may be used by attackers.
Advisories and additional details are available from sources including VulDB (ctiid.347274, id.347274, submit.754499), a GitHub issue at LX-66-LX/cve-new/issues/22, and the D-Link website. Security practitioners should review these references for any recommended mitigations, patches, or workarounds.
