net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup
In the Linux kernel, the following vulnerability has been resolved: net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup Raw IP packets have no MAC header, leaving skb->mac_header uninitialized. This can trigger kernel panics on ARM64 when xfrm or other subsystems access the offset due to strict alignment checks. Initialize the MAC header to prevent such crashes. This can trigger kernel panics on ARM when running IPsec over the qmimux0 interface.
