    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: fix potential out-of-bounds read in iwl_mvm_nd_match_info_handler()\n\nThe memcpy function assumes the dynamic array notif->matches is at least\nas large as the number of bytes to copy. Otherwise, results->matches may\ncontain unwanted data. To guarantee safety, extend the validation in one\nof the checks to ensure sufficient packet length.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.",
