UBUNTU-CVE-2026-98333

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...

CVE-2026-98325

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: set up the TX info early to fix failure paths The previous commit 2c51457d930f "wifi: mac80211: free ack status frame on TX header build failure" cleaned up the leak, but still left the code a bit messy and the...

CVE-2026-98336

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-2026-98331

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: unlist vifs when their netdev is unregistered mac80211 only removes vifs from the local-interfaces list when an interface is removed via ieee80211ifremove, before it unregisters the netdev. However, it's possible...

CVE-2026-98327

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: mesh: reset the CSA state when leaving ifmsh-csa is allocated in ieee80211meshcsabeacon and only freed in ieee80211meshfinishcsa, i.e. when the channel switch completes. Leaving the mesh while a switch is still...

CVE-2026-98346

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't get the radio mask for netdev-less wdevs cfg80211calculatebidata calls rdevgetradiomask with wdev-netdev, which can be NULL and then crashes in mac80211. To avoid that, invert the order of checks since...

CVE-2026-98328

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: add HE 6 GHz capability in the scan elems len The HE 6 GHz Band Capability element is in the probe request for every band if 6 GHz is supported, so add the size to scanieslen. Otherwise, building probe request...

CVE-2026-98182

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: refuse to make a monitor active when it has no queue A monitor interface only gets a TXQ if it's created active, and one can't be added later. Setting the flag on a down interface is still allowed, so the driver i...

CVE-2026-98337

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't start a ROC while scanning The ROC work can be pending when a scan starts which requires ROC list to be empty, but that's possible, and then a new ROC can be added to the list and the work will pick it up...

CVE-2026-98335

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...
