A vulnerability in the Linux kernel's rtw88 WiFi driver was resolved by adding a NULL check for chip->edcca_th in the function rtw_fw_adaptivity_result(). The issue caused a kernel oops when devices with the 8821CE chip, which do not define edcca_th, dereferenced this pointer without validation. The fix prevents the NULL dereference and resulting kernel crash but does not address the underlying cause. This vulnerability affects specific Linux kernel versions listed and was tested to avoid regressions on other chips.
