In the Linux kernel, the following vulnerability has been resolved: net: spacemit: Fix error handling in emac_tx_mem_map() The DMA mappings were leaked on mapping error. Free them with the existing emac_free_tx_buf() function.

A flaw was found in the Linux kernel's `spacemit` network driver. Specifically, an error in the `emac_tx_mem_map()` function could result in the leakage of Direct Memory Access (DMA) mappings. This resource management issue may lead to a denial of service, impacting system availability.
