      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: bound element ID read when checking non-inheritance\n\ncfg80211_is_element_inherited() reads the first data octet of the\ncandidate element (id = elem->data[0]) to look it up in an extension\nnon-inheritance list. It does so after testing elem->id, but without\nverifying that the element actually has a data octet. A zero-length\nextension element (WLAN_EID_EXTENSION with length 0) therefore makes it\nread one octet past the end of the element.\n\n_ieee802_11_parse_elems_full() runs this check for every element of a\nframe once a non-inheritance context exists -- e.g. while parsing a\nper-STA profile of a Multi-Link element in a (re)association response,\nor a non-transmitted BSS profile -- so a crafted frame from an AP can\ntrigger a one-octet slab-out-of-bounds read during element parsing:\n\n  BUG: KASAN: slab-out-of-bounds in cfg80211_is_element_inherited\n  Read of size 1 ... in net/wireless/scan.c\n\nReturn early (treat the element as inherited) when an extension element\ncarries no data, mirroring the existing handling of empty ID lists.\n\nThe bug was found by fuzzing ieee802_11_parse_elems_full() under KASAN.",
