A fix is available — apply it.

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

wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()

mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to be freed eventually by mt76_mcu_skb_send_msg(). However, currently if an intermediate function fails before sending, the allocated skb is leaked.

Specifically, mt76_connac_mcu_sta_wed_update() and mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory leak in the error path.

Fix this by explicitly freeing the skb in these error paths. Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on mt7996_mcu_sta_key_tlv error") made a similar change.

Compile tested only. Issue found using a prototype static analysis tool and code review.
