Vulnerability from github – Published: 2026-09-24 18:31 – Updated: 2026-09-24 18:31

Details

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.
