CVE-2026-98339

The Linux kernel contains a vulnerability in the wifi: cfg80211 component where stale BSS entries are not correctly filtered during removal. When an associated Access Point (AP) switches to a channel with an existing BSS entry, the function cfg80211_update_assoc_bss_entry() removes the entry to a...

CVE-2026-98337

A vulnerability exists in the Linux kernel 's mac80211 wifi subsystem where ROC (Radio Out Channel) work could be started while a scan is in progress. This occurs because pending ROC work might remain when a scan begins, and new ROCs can be added to the list, potentially causing a warning in net/...

CVE-2026-98336 wifi: mac80211: don't offload TC setup on AP_VLAN interfaces

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't offload TC setup on APVLAN interfaces APVLAN interfaces are purely virtual, so don't try to offload TC setup to drivers. We can't really use the AP interface either since we may not know it all the time, and...

CVE-2026-98336

The Linux kernel contains a vulnerability in the wifi: mac80211 component where the system attempts to offload TC (traffic control) setup to drivers for AP_VLAN interfaces . Because these interfaces are purely virtual, the offload attempt is inappropriate and can fail as the AP interface may be u...

CVE-2026-98335 wifi: mac80211: abort chanswitch when leaving a mesh

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: abort chanswitch when leaving a mesh The code in ieee80211stopmesh leaves CSA active, but leaving the mesh released the channel context, so the CSA finalize work crashes: Oops: general protection fault, probably f...

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: abort chanswitch when leaving a mesh The code in ieee80211stopmesh leaves CSA active, but leaving the mesh released the channel context, so the CSA finalize work crashes: Oops: general protection fault, probably f...

CVE-2026-98335

The Linux kernel contains a vulnerability in the mac80211 wifi subsystem where the ieee80211_stop_mesh() function fails to properly abort a channel switch (CSA) when leaving a mesh. Because the function leaves CSA active while releasing the channel context, it results in a null-pointer dereferenc...

CVE-2026-98334

A vulnerability exists in the Linux kernel 's mac80211 WiFi subsystem where the ieee80211_start_ap() function can set enable_beacon and beacon_int but fail to reset them upon an error. This persistent state can cause a divide error (Oops) in hwsim when scanning attempts to restore beaconing. Addi...

CVE-2026-98333 wifi: mac80211: reset the LED state when ifup fails

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: reset the LED state when ifup fails When the first interface comes up, the radio LED is turned on. This can start the TPT trigger timer, which continues running. But if bringing up the interface fails then the tim...
