Title
ntb: ntb_hw_switchtec: Fix array-index-out-of-bounds access
Summary
In the Linux kernel, the following vulnerability has been resolved: ntb: ntb_hw_switchtec: Fix array-index-out-of-bounds access Number of MW LUTs depends on NTB configuration and can be set to MAX_MWS, This patch protects against invalid index out of bounds access to mw_sizes When invalid access print message to user that configuration is not valid.
