CVE-2026-53182

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211_parse_rnr_elems() function, responsible for parsing EMA RNR (Enhanced Multiple Access Reduced Neighbor Report) lists, does not properly handle an excessive number of nested NL80211_ATTR_EMA_RNR_ELEMS inputs. This improper input validation could allow a remote attacker to cause a denial of service (DoS) by providing an oversized EMA RNR list, potentially leading to system instability or a crash.
