CVE-2026-64280

A flaw was found in the Linux kernel's dfl-afu FPGA driver. A local user could exploit this vulnerability by providing an excessively large length value during Direct Memory Access DMA mapping operations. The system incorrectly truncates this value, leading to memory corruption. This could allow ...

CVE-2026-64280

The CVE concerns the Linux kernel’s FPGA driver for DFL FPGA management (fpga: dfl-afu). A 64-bit length passed via the DFL_FPGA_PORT_DMA_MAP ioctl to afu_ioctl_dma_map() can overflow when computing the number of pages (length >> PAGE_SHIFT) passed to pin_user_pages_fast(), since npages is ...
