  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: check for PCI upstream bridge existence\n\npci_upstream_bridge() returns NULL if the device is on a root bus.  If\n8821CE is installed in the system with such a PCI topology, the probing\nroutine will crash.  This has probably been unnoticed as 8821CE is mostly\nsupplied in laptops where there is a PCI-to-PCI bridge located upstream\nfrom the device.  However the card might be installed on a system with\ndifferent configuration.\n\nCheck if the bridge does exist for the specific workaround to be applied.\n\nFound by Linux Verification Center (linuxtesting.org) with Svace static\nanalysis tool.",
