In the Linux kernel, the following vulnerability has been resolved:

spi: amlogic: spifc-a4: Fix DMA mapping error handling

Fix three bugs in aml_sfc_dma_buffer_setup() error paths:
1. Unnecessary goto: When the first DMA mapping (sfc->daddr) fails,
   nothing needs cleanup. Use direct return instead of goto.
2. Double-unmap bug: When info DMA mapping failed, the code would
   unmap sfc->daddr inline, then fall through to out_map_data which
   would unmap it again, causing a double-unmap.
3. Wrong unmap size: The out_map_info label used datalen instead of
   infolen when unmapping sfc->iaddr, which could lead to incorrect
   DMA sync behavior.
