Title
wifi: carl9170: fix buffer overflow in rx_stream failover path
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: fix buffer overflow in rx_stream failover path The failover continuation in carl9170_rx_stream() copies the full tlen from the second USB transfer instead of capping at rx_failover_missing bytes. When both transfers are near maximum size, the total exceeds the 65535-byte failover SKB, triggering skb_over_panic. Limit the copy size to the missing byte count. [Fix checkpatch CHECK:PARENTHESIS_ALIGNMENT]
