CVE-2023-53785

CVE-2023-53785 : In MT76 MT7921/MT7921_USB_SDIO path, code assumed adequate headroom in an skb when prepending SDIO headers, which could trigger kernel panics if the skb came from a non-net-core path (e.g., bridged interfaces). The fix adds a skb_cow_head() call in mt7921_usb_sdio_tx_prepare_skb(...
