CVE-2026-74324: Linux

Описание

Оригинално описание

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.
