CVE-2026-46092

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. When the 8821CE device is installed on a system where it is on a root bus, the driver's probing routine does not properly check for the existence of a PCI upstream bridge. This oversight can lead to a system crash, resulting in a denial o...
