CVE-2026-98326

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: mesh: release the channel if start fails ieee80211joinmesh acquires a channel context and then calls ieee80211startmesh, which can fail. In that case, the chanctx isn't released then interface removal will attempt...

UBUNTU-CVE-2026-98332

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: only operate on TDLS peers in the TDLS code ieee80211tdlsoper can operate on the AP station, which then yields various warnings when the AP station is removed then or at a later point in time after being confused...

UBUNTU-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...

UBUNTU-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-2026-98346 wifi: cfg80211: don't get the radio mask for netdev-less wdevs

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-2026-98346

The Linux kernel contains a vulnerability in the cfg80211 component where the function cfg80211_calculate_bi_data() calls rdev_get_radio_mask() using wdev->netdev. Because wdev->netdev can be NULL for certain network device types, this leads to a crash in mac80211 . The fix involves inverti...

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

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...
