What is CVE-2026-0455?

The Versal AI Edge Series Gen 2 Peripheral Protection Unit contains a significant vulnerability where the inter-processor interrupt (IPI) buffers fail to block unauthorized access. This flaw permits any processor within the system-on-chip (SoC) that has access to an IPI channel to read and manipulate the entire IPI buffer register space as well as the IPI no-buffer register control space, potentially leading to data leakage and unauthorized data modification.
