Descriptions

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.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gve: agrega comprobaciones de puntero NULL al liberar irqs. Al liberar bloques de notificaciones, indexamos priv->msix_vectors. Si no pudimos asignar priv->msix_vectors (consulte abort_with_msix_vectors), esto podría provocar una desreferencia del puntero NULL si el controlador está descargado.
