  "description": "In the Linux kernel, the following vulnerability has been resolved:  mt76: fix monitor mode crash with sdio driver  mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size\u002B6 bytes with skb_pull(), that would trigger \u0022BUG_ON(skb-\u003Elen \u003C skb-\u003Edata_len)\u0022 in __skb_pull().  To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer.  [   52.007562] kernel BUG at include/linux/skbuff.h:2313!
