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.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2
