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

wifi: iwlwifi: pcie: fix NULL pointer dereference in iwl_pcie_irq_rx_msix_handler()

rxq can be NULL only when trans_pcie->rxq is NULL and entry->entry is zero. For the case when entry->entry is not equal to 0, rxq won't be NULL even if trans_pcie->rxq is NULL. Modify checker to check for trans_pcie->rxq.
