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.
