cve-2026-46092

CVE-2026-46092 is a Linux kernel vulnerability in the Realtek rtw88 Wi-Fi PCI driver that causes a crash when an RTL8821CE device is connected directly to a PCI root bus. Disclosed by kernel.org and added to the NVD on May 27, 2026, the bug is fixed by a two-line logic change. While it does not carry an NVD severity score and is not a remote-code-execution issue, it affects users running Linux on uncommon hardware, repurposing laptop wireless cards, or managing fleets where rare PCI topologies occur. The vulnerability highlights how modern driver security depends on proving assumptions about hardware configurations.
