Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: nl80211: reject oversized EMA RNR lists<br /> <br /> nl80211_parse_rnr_elems() stores the parsed element count in a<br /> u8-backed cfg80211_rnr_elems::cnt field and uses that count to size<br /> the flexible array allocation.<br /> <br /> Reject nested NL80211_ATTR_EMA_RNR_ELEMS input once the count reaches<br /> 255, before incrementing it again. This keeps the parser aligned with<br /> the data structure it fills and matches the existing bound check used<br /> by nl80211_parse_mbssid_elems().
