Original description
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix sched scan IE sizing Scheduled scan built the probe request before iwl_mvm_scan_fits(), so oversized IEs could be copied into the fixed preq buffer before length validation. Move iwl_mvm_build_scan_probe() after the fits check. Also advertise max_sched_scan_ie_len using iwl_mvm_max_scan_ie_len() so userspace limits account for driver-inserted DS/TPC bytes.
