In the Linux kernel, the following vulnerability has been resolved:

igb: Do not free q_vector unless new one was allocated

Avoid potential use-after-free condition under memory pressure. If the kzalloc() fails, q_vector will be freed but left in the original adapter->q_vector[v_idx] array position.
