It seems that a new Linux Kernel was released late last week. The new version is the Linux Kernel 5.19.1.
This version seems to include some drivers for WiFi and Bluetooth devices, particularly, support for the Infineon’s WiFi 6 CYW55572 Bluetooth, a variant of the Broadcom BCM4349B1 (Infineon CYW4349B1?), and Realtek’s Bluetooth 4.2 RTL8852C. It also includes a fix for an Intel vulnerability.
