CVE-2026-68311

wifi: mt76: mt7925: guard link STA in decap offload

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7925: guard link STA in decap offload

mt7925_sta_set_decap_offload() iterates over the vif valid_links mask
when updating decap offload state for an MLO station. The station may not
have a link STA for every valid link of the vif, so mt792x_sta_to_link()
can return NULL for a link that belongs to the vif but not to the station.

The function currently dereferences mlink before checking whether the
link WCID is ready. If mlink is NULL, setting or clearing
MT_WCID_FLAG_HDR_TRANS dereferences a NULL pointer.

Skip links without a station link before touching mlink->wcid.
