Description OSIDB Bzimport 2025-10-01 09:01:55 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7996: add missing check for rx wcid entries

Non-station wcid entries must not be passed to the rx functions.
In case of the global wcid entry, it could even lead to corruption in the wcid
array due to pointer being casted to struct mt7996_sta_link using container_of.
