      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: advance loop vars in cfg80211_merge_profile()\n\ncfg80211_merge_profile() reassembles a Multi-BSSID non-transmitted BSS\nprofile that has been split across multiple consecutive MBSSID elements.\nIts while-loop calls\n\n\tcfg80211_get_profile_continuation(ie, ielen, mbssid_elem, sub_elem)\n\nbut never advances mbssid_elem or sub_elem inside the body.  Each\niteration therefore searches for a continuation that follows the same\nfixed pair; the helper returns the same next_mbssid; and the same\nnext_sub bytes are memcpy()'d into merged_ie at a growing offset until\nthe buffer fills.\n\nAdvance both mbssid_elem and sub_elem to the just-consumed continuation\nso the next call to cfg80211_get_profile_continuation() searches for a\nfurther continuation beyond it (or returns NULL when none exists).\n\nA specially-crafted malicious beacon can take advantage of this bug\nto cause the kernel to spend an excessive amount of time in\ncfg80211_merge_profile (up to as much as 2ms per beacon received),\nwhich could theoretically be abused in some way.",
