CVE-2026-46092

Medium

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.
