CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's mt7925 driver, specifically in the handling of response messages during test mode queries. An insufficient length validation in the memcpy operation can lead to a buffer over-read, potentially exposing sensitive data to userspace applications. Organizations utilizing affected Linux distributions with the mt7925 driver should prioritize this issue to mitigate the risk of data leakage.
Original NVD Description
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.
