      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: cancel pmsr_free_wk in cfg80211_pmsr_wdev_down\n\nWhen the nl80211 socket that originated a PMSR request is\nclosed, cfg80211_release_pmsr() sets the request's nl_portid\nto zero and schedules pmsr_free_wk to process the abort\nasynchronously. If the interface is concurrently torn down\nbefore that work runs, cfg80211_pmsr_wdev_down() calls\ncfg80211_pmsr_process_abort() directly. However, the already-\nscheduled pmsr_free_wk work item remains pending and may run\nafter the interface has been removed from the driver. This\ncould cause the driver's abort_pmsr callback to operate on a\ntorn-down interface, leading to undefined behavior and\npotential crashes.\n\nCancel pmsr_free_wk synchronously in cfg80211_pmsr_wdev_down()\nbefore calling cfg80211_pmsr_process_abort(). This ensures any\npending or in-progress work is drained before interface teardown\nproceeds, preventing the work from invoking the driver abort\ncallback after the interface is gone.",
