AI-suggested

The vulnerability is fixed in the Linux kernel versions identified by the listed commit hashes. Users should update to a Linux kernel version that includes these fixes. Since this is not a cloud service, manual patching or kernel upgrade is required.

Description

A memory management issue in the Linux kernel's rtw88 WiFi driver was fixed by switching to device-managed memory allocation. This change also resolves a memory leak in the rtw_register_hw() function where supported bands were not freed on error paths.
