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

wifi: iwlwifi: pcie: null RX pointers after free

When iwl_pcie_tx_init() fails after RX init, nic init unwinds via
iwl_pcie_rx_free().

The freed RX members stayed non-NULL on the live transport object,
so later teardown or retry could touch stale RX state.
Set rx_pool, global_table, rxq, and alloc_page to NULL after free
to make repeated cleanup and retry paths safe.
