Pending analysis

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: iwlwifi: mld: cancel mlo_scan_start_wk<br /> <br /> mlo_scan_start_wk is not canceled on disconnection. In fact, it is not<br /> canceled anywhere except in the restart cleanup, where we don&amp;#39;t really<br /> have to.<br /> <br /> This can cause an init-after-queue issue: if, for example, the work was<br /> queued and then drv_change_interface got executed.<br /> <br /> This can also cause use-after-free: if the work is executed after the<br /> vif is freed.
