- Summary
- wifi: mac80211: set info->band for 802.3 encap offload frames
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: set info->band for 802.3 encap offload frames
Unlike the 802.11 TX paths, ieee80211_8023_xmit() does not set info->band from the channel context on non-MLD interfaces. It stays at 0, so ieee80211_get_tx_rates() uses the wrong band for these frames.
Set it the same way as ieee80211_build_hdr(): drop the frame if there is no channel context, and leave the band at 0 on MLD interfaces.
