CVE-2026-23185

Estado: ModificadaAlta (7.8)—

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.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
