CVE-2026-97511

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: avoid out-of-bounds access in monitor
In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array.
Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it.
