Description (CNA)
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.

ADP enrichment
A flaw was found in the Linux kernel's iwlwifi driver. This vulnerability occurs because a specific work item, `mlo_scan_start_wk`, is not properly canceled when a network device disconnects. This oversight can lead to a use-after-free condition, where the system attempts to access memory that has already been released. A local attacker with high privileges could potentially exploit this to cause a system crash (denial of service) or execute unauthorized code.
