    net: wimax/i2400m: fix NULL-deref at probe · 6e526fdf
    Johan Hovold authored
    Make sure to check the number of endpoints to avoid dereferencing a
    NULL-pointer or accessing memory beyond the endpoint array should a
    malicious device lack the expected endpoints.
    The endpoints are specifically dereferenced in the i2400m_bootrom_init
    path during probe (e.g. in i2400mu_tx_bulk_out).
    Fixes: f398e424 ("i2400m/USB: probe/disconnect, dev init/shutdown
    and reset backends")
