  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: amlogic: spifc-a4: Fix DMA mapping error handling\n\nFix three bugs in aml_sfc_dma_buffer_setup() error paths:\n1. Unnecessary goto: When the first DMA mapping (sfc-\u003edaddr) fails,\n   nothing needs cleanup. Use direct return instead of goto.\n2. Double-unmap bug: When info DMA mapping failed, the code would\n   unmap sfc-\u003edaddr inline, then fall through to out_map_data which\n   would unmap it again, causing a double-unmap.\n3. Wrong unmap size: The out_map_info label used datalen instead of\n   infolen when unmapping sfc-\u003eiaddr, which could lead to incorrect\n   DMA sync behavior.",
