In the Linux kernel, the following vulnerability has been resolved: wifi: rtl818x: Fix potential memory leaks in rtl8180_init_rx_ring() In rtl8180_init_rx_ring(), memory is allocated for skb packets and DMA allocations in a loop. When an allocation fails, the previously successful allocations are not freed on exit. Fix that by jumping to err_free_rings label on error, which calls rtl8180_free_rx_ring() to free the allocations. Remove the free of rx_ring in rtl8180_init_rx_ring() error path, and set the freed priv->rx_buf entry to null, to avoid double free.
