A vulnerability in the Linux kernel's spacemit network driver was resolved involving improper handling of TX descriptors on fragment mapping failure. The emac_tx_mem_map() function prematurely marks TX descriptors as owned before all buffer fragments are successfully mapped. If a fragment mapping fails, the cleanup path does not clear the descriptor memory, leaving stale DMA addresses that can be reused incorrectly. This can cause the DMA engine to fetch unmapped, invalid addresses. The fix ensures descriptors are cleared properly on mapping failure.
