CVE-2026-98700

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.
