Description
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix NULL pointer dereference in i40e_dbg_dump_desc
When trying to dump VFs VSI RX/TX descriptors
using debugfs there was a crash
due to NULL pointer dereference in i40e_dbg_dump_desc.
Added a check to i40e_dbg_dump_desc that checks if
VSI type is correct for dumping RX/TX descriptors.
