In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: bound element ID read when checking non-inheritance
cfg80211_is_element_inherited() reads the first data octet of the candidate element (id = elem->data[0]) to look it up in an extension non-inheritance list. It does so after testing elem->id, but without verifying that the element actually has a data octet. A zero-length extension element (WLAN_EID_EXTENSION with length 0) therefore makes it read one octet past the end of the element.
_ieee802_11_parse_elems_full() runs this check for every element of a frame once a non-inheritance context exists -- e.g. while parsing a per-STA profile of a Multi-Link element in a (re)association response, or a non-transmitted BSS profile -- so a crafted frame from an AP can trigger a one-octet slab-out-of-bounds read during element parsing:
BUG: KASAN: slab-out-of-bounds in cfg80211_is_element_inherited Read of size 1 ... in net/wireless/scan.c
Return early (treat the element as inherited) when an extension element carries no data, mirroring the existing handling of empty ID lists.
The bug was found by fuzzing ieee802_11_parse_elems_full() under KASAN.
