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:
- Unnecessary goto: When the first DMA mapping (sfc->daddr) fails, nothing needs cleanup. Use direct return instead of goto.
- 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.
- 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.
