CVE-2026-53258

In the Linux kernel, the following vulnerability has been resolved: wifi: fix leak if split 6 GHz scanning fails rdev-intscanreq is leaked if cfg80211scan fails. Note that it's supposed to be released at cfg80211scandone but this doesn't happen as rdev-scanreq is NULL at that point, too, leading ...

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject oversized EMA RNR lists nl80211parsernrelems stores the parsed element count in a u8-backed cfg80211rnrelems::cnt field and uses that count to size the flexible array allocation. Reject nested...

CVE-2026-53257

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if ehtcap is set but ehtoper isn't. Rather than fixing that for the individual users, enforce that both HE/EHT have consistent elemen...

CVE-2026-53257

The CVE-2026-53257 entry concerns the Linux kernel wifi subsystem (cfg80211/mac80211). The issue arises when HE (High Efficiency) and EHT elements are inconsistent between capabilities and operations, which could trigger a crash if eht_cap is set but eht_oper isn’t. The vulnerability is addressed...

CVE-2026-53258

CVE-2026-53258 affects the Linux kernel WiFi stack: when a 6 GHz split scan fails, rdev->int_scan_req is leaked because cfg80211_scan() fails before ___cfg80211_scan_done() releases it. The leak is observed in kernel mode tracing (kmemleak) and is associated with a wpa_supplicant process in th...
