CVE-2026-51221: n/a
A buffer overflow in the Get_Attribute_List function of EIPStackGroup OpENer commit 76b95c allows attackers to cause a Denial of Service (DoS) via supplying a crafted Common Packet Format (CPF) packet.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the Get_Attribute_List function within the EIPStackGroup OpENer project, specifically triggered by crafted CPF packets. Successful exploitation leads to denial of service by crashing or destabilizing the affected service. The CVSS 3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability. No patch or vendor advisory is currently available to confirm remediation status.
Potential Impact
The vulnerability allows unauthenticated remote attackers to cause a denial of service, impacting availability of the affected system. There is no impact on confidentiality or integrity according to the CVSS vector. This can disrupt operations relying on the EIPStackGroup OpENer component.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing network-level protections such as filtering or rate limiting CPF packets from untrusted sources to reduce exposure.
