mt76: mt7925: cancel pending mlo_pm_work","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7925: cancel pending mlo_pm_work\n\nIf the device is reset, suspended or unregistered within that window,\nthe pending work can still run and access vif/bss data that may already\nbe freed, or send MCU commands while the firmware is not available.\n\nAdd cancel_delayed_work_sync(&dev->mlo_pm_work) in all relevant teardown\nand suspend paths:\n\n - mt7925_mac_reset_work()        (chip reset recovery)\n - mt7925e_unregister_device()    (PCIe unbind)\n - mt7925_pci_suspend()           (PCIe bus suspend)\n - mt7925_suspend()               (mac80211 suspend)\n - mt7925u_suspend()              (USB bus / runtime suspend)\n\nThis ensures the work is stopped before the device state becomes\ninvalid.","state":0,"publishedAt":"2026-09-11T19:44:04.796+00:00","modifiedAt":"2026-10-19T08:48:14.517+00:00","affected":[{"ecosystem":"Vendor
