CVE-2024-35946 is a null-pointer access vulnerability in the Linux kernel's rtw89 Wi-Fi driver. During Wi-Fi scan cancellation, the driver may use a virtual interface that was not performing the scan rather than the actual scanning interface. This incorrect interface selection can trigger a null-pointer access when aborting the scan. The fix changes scan cancellation to use the actual scanning virtual interface.
