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

A flaw was found in the Linux kernel's iwlwifi component. This vulnerability involves a potential out-of-bounds read within the `iwl_mvm_nd_match_info_handler()` function. The `memcpy` function, used in this handler, does not adequately validate the size of an incoming packet, which could allow an attacker to read unintended data from memory. This could potentially lead to information disclosure.
