CVE-2026-98424 wifi: cfg80211: undo netns switch if renaming the wiphy fails

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: undo netns switch if renaming the wiphy fails Once all the interfaces have been moved, cfg80211switchnetns moves the wiphy itself by setting its network namespace and then renaming it, which makes sysfs move it. T...

CVE-2026-98424

The Linux kernel contains a vulnerability in the cfg80211 component where the cfg80211_switch_netns() function fails to handle errors during the wiphy renaming process. When renaming the wiphy fails due to allocation errors, the component can leave the system in an inconsistent state where object...

CVE-2026-98423

The Linux kernel contains a vulnerability in the wifi: mac80211_hwsim component where frames from wmediumd could be handed to mac80211 while the radio is stopping. This occurs because the code checks the ->started status, but the radio can be stopped immediately after that check but before fra...

CVE-2026-98421

The Linux kernel contains a vulnerability in the wifi: mac80211 component regarding TDLS setup confirm . The issue occurs because the system may attempt to send a setup confirm to a station that does not exist, triggering a WARN_ON_ONCE(!sta || !ap_sta) warning during frame construction. To resol...

CVE-2026-98422

The Linux kernel contains a vulnerability in the wifi: mac80211 component where the AP_VLAN tailroom counter is not properly managed. Specifically, on ifup , AP_VLAN interfaces inherit the crypto_tx_tailroom_needed_cnt from the AP interface, but this counter is never decremented unless the AP its...
