Summary

The Linux kernel from 5.7 is affected by a flaw in the mac80211 Wi-Fi stack. The 802.3 encapsulation offload transmit path does not set the frame band from the channel context on non-MLD interfaces, so the band stays at 0 and rate selection uses the wrong band. Frames that take this path can get wrong transmit rates.

Description from the CNA

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.
