CVE-2026-85028: Creation of Temporary File in Directory with Insecure Permissions in AWS FPGA Development Kit
Bulletin ID: 2026-096-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/03/2026 11:00 AM PDT Description: The AWS FPGA Developer Kit is a hardware-software development kit that enables developers to create accelerators for the high-performance accelerator cards on EC2 F2 instances. We identified CVE-2026-85028, where a creation of a temporary file in a directory with insecure permissions in the FPGA management tool installation component in AWS FPGA Development Kit (aws-fpga) before 2.3.4 might allow local users to execute arbitrary code with root privileges via crafted shell content placed at a predictable path in a world-writable temporary directory, which the installation step reads after elevating its own privileges. Impacted versions: < 2.3.4 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
