This patch series addresses validation issues in the virtchnl interface of the ice driver. These fixes correct improper value checking, ensuring that the driver can properly handle and reject invalid inputs from potentially malicious VFs. By fixing validation mechanisms, these patches strictly enforce existing constraints to prevent out-of-bounds scenarios, making the system more robust against incorrect or unexpected data.
