Official description

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: cancel mlo_scan_start_wk mlo_scan_start_wk is not canceled on disconnection. In fact, it is not canceled anywhere except in the restart cleanup, where we don't really have to. This can cause an init-after-queue issue: if, for example, the work was queued and then drv_change_interface got executed. This can also cause use-after-free: if the work is executed after the vif is freed.
