ABB Ability Edgenius Vulnerability CVE-2026-31431: Linux Kernel Flaw Allows Privilege Escalation
ABB Ability Edgenius versions 3.2.0.0 through 3.2.4.0 are affected by CVE-2026-31431, a Linux kernel vulnerability known as 'Copy Fail'. The flaw resides in the kernel's cryptographic subsystem (algif_aead interface) and may allow a locally authenticated user or a compromised container workload to gain elevated root privileges. Exploitation requires local code execution, but in shared or multi-tenant environments the risk is heightened. ABB has released version 3.2.4.1 as a fix, and customers are urged to update promptly.
