Description

In the Linux kernel, the following vulnerability has been resolved: gve: Add NULL pointer checks when freeing irqs. When freeing notification blocks, we index priv->msix_vectors. If we failed to allocate priv->msix_vectors (see abort_with_msix_vectors) this could lead to a NULL pointer dereference if the driver is unloaded.
