In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: fix potential out-of-bounds read in iwl_mvm_nd_match_info_handler()

The memcpy function assumes the dynamic array notif->matches is at least

as large as the number of bytes to copy. Otherwise, results->matches may

contain unwanted data. To guarantee safety, extend the validation in one

of the checks to ensure sufficient packet length.
