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

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

rxq can be NULL only when transpcie->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 transpcie->rxq is NULL. Modify checker to check for trans_pcie->rxq.
