Data corruption via invalid PMFW DMA read
Published Aug 13, 2024 · Updated Nov 4, 2024
Out-of-bounds read in PMFW on affected AMD Radeon graphics cards allows local users with high privileges to corrupt SRAM data. PMFW insufficiently validates a DRAM address before a DMA transfer, permitting data from an invalid DRAM location to be read into SRAM. Local access and high privileges are required, and the documented consequence is loss of data integrity rather than code execution.
