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

wifi: rtw89: pci: configure manual DAC mode via PCI config API only

To support 36-bit DMA, configure chip proprietary bit via PCI config API or chip DBI interface. However, the PCI device mmap isn't set yet and the DBI is also inaccessible via mmap, so only if the bit can be accessible via PCI config API, chip can support 36-bit DMA. Otherwise, fallback to 32-bit DMA.

With NULL mmap address, kernel throws trace:
