- 7.0 HIGH — CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Description
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.
