CVE-2026-0455
What it is
The Versal™ AI Edge Series Gen 2 Peripheral Protection Unit (XPPU) for the inter-processor interrupt (IPI) buffers does not block unauthorized access as expected. This allows processors in the SoC with any IPI channel access the ability to both read and write to the entire IPI buffer register space as well as the IPI no-buffer register control space.
