Description OSIDB Bzimport 2025-09-15 15:08:41 UTC 
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.
