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

wifi: mt76: mt7925: validate skb length in testmode query

In mt7925_tm_query(), the response skb from mt76_mcu_send_and_get_msg()
is used in a memcpy without validating its length:

memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN);

where MT7925_EVT_RSP_LEN is 512. If the firmware returns a response
shorter than 520 bytes (8 + 512), this reads beyond the skb data
buffer. The over-read data is then returned to userspace via nla_put()
in mt7925_testmode_dump().

Add a length check before the memcpy to ensure the skb contains
sufficient data.
