ABB Ability Edgenius

View CSAF Summary ABB is aware of public reports of a vulnerability CVE‑2026‑31431 (Copy Fail) in the product versions listed as affected in the advisory. An update is available that resolves a publicly reported vulnerability. CVE‑2026‑31431 (Copy Fail) is a Linux kernel vulnerability that may allow a locally authenticated user or compromised container workload to gain elevated (root) privileges on affected systems. Once root access is obtained, the attacker can effectively gain complete control of the system The following versions of ABB Ability Edgenius are affected: Ability Edgenius >=3.2.0.0| =3.2.0.0| =3.2.0.0| =3.2.0.0| =3.2.0.0| =3.2.0.0|<3.2.4.1 installed on ABB Ability Edgenius Server - vE1000 Product Status: known_affected Remediations Vendor fix The problem is corrected in the following product versions: - Edgenius 3.2.4.1 ABB recommends that customers apply the update at earliest convenience. Mitigation Mitigating factors describe conditions and circumstances that make an attack that exploits the vulnerability difficult or less likely to succeed. Refer to section General security recommendations for further advise on how to keep your system secure. Recommended mitigation factors - Limit access to ssh or cockpit - By default, no additional lower privilege users are present on Edgenius installations Relevant CWE: CWE-669 Incorrect Resource Transfer Between Spheres Metrics CVSS Version Base Score Base Severity Vector String 3.1 7.8 HIGH CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Acknowledgments ABB PSIRT reported this vulnerability to CISA.

Frequently Asked Questions What causes the vulnerability? - A flaw was found in the Linux kernel's algif_aead cryptographic algorithm interface. An incorrect 'in-place operation' was introduced, where the source and destination data mappings were different. This could lead to unexpected behavior or data integrity issues during cryptographic operations, potentially impacting the reliability of encrypted communications. What is Edgenius? - ABB Ability™ Edgenius is an edge computing platform that - Connects to control systems, devices, and equipment - Collects and contextualizes operational data - Hosts applications that deliver real-time insights and AI-driven recommendations What might an attacker use the vulnerability to do? - Successful exploitation could enable a local user attacker to gain administrative control of the system node, execute arbitrary code, or cause the node to become unavailable. How could an attacker exploit the vulnerability? - An attacker could exploit this vulnerability after obtaining local access to the system. By invoking the Linux kernel’s affected cryptographic interface (algif_aead), the attacker can trigger incorrect memory handling in the kernel. This allows the attacker to escalate privileges from a normal user to full administrative (root) access on the affected system node Could the vulnerability be exploited remotely? - No, to exploit this vulnerability an attacke
