Local DMA-buffer read and write via improper permissions
Published Jan 31, 2025 · Updated Mar 20, 2025
Improper privilege handling in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows local users to read and write DMA buffers. The DDK kernel module accepts improper operations on imported or exported DMA buffers, including writes to buffers designated read-only. Local execution as a non-privileged user is required, and successful access can disclose or alter buffer contents and affect host operation.
