[iwl-net,v3,0/5] ice: fix validation issues in virtchnl parameters

Message

Szapar-Mudlaw, Martyna March 4, 2025, 11:08 a.m. UTC

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.
