Summary
In the Linux kernel, the following vulnerability has been resolved: net: libwx: fix Tx L4 checksum The hardware only supports L4 checksum offload for TCP/UDP/SCTP protocol. There was a bug to set Tx checksum flag for the other protocol that results in Tx ring hang. Fix to compute software checksum for these packets.
