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

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

wifi: iwlwifi: mvm: fix potential out-of-bounds read in iwlmvmndmatchinfo_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.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
