Commit da1b9a55ff11 (\"wifi: p54: prevent buffer-overflow in\np54_rx_eeprom_readback()\") closed the destination overflow by copying a\nfixed priv->eeprom_slice_size (and rejecting a mismatched advertised len),\nbut the source side is still unbounded: nothing verifies the frame is long\nenough to supply that many bytes.\n\nA malicious USB device can send a short frame whose advertised len matches\npriv->eeprom_slice_size while the payload is truncated.
