CVE-2026-31779CVE-2026-31779
Description
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.
