No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: check for PCI upstream bridge existence
pci upstream bridge() returns NULL if the device is on a root bus. If
8821CE is installed in the system with such a PCI topology, the probing
routine will crash. This has probably been unnoticed as 8821CE is mostly
supplied in laptops where there is a PCI-to-PCI bridge located upstream
from the device. However the card might be installed on a system with
different configuration.
Check if the bridge does exist for the specific workaround to be applied.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
