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-2026-98335 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...

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-2026-98314 ALSA: pcm: set timer->private_data before registering the PCM timer

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: set timer-privatedata before registering the PCM timer sndpcmtimerinit calls snddeviceregister to link the new struct sndtimer into the global timer list while it still carries hw.cresolution = sndpcmtimerresolution an...

CVE-2026-98314

The Linux kernel contains a vulnerability in the ALSA subsystem where snd_pcm_timer_init() calls snd_device_register() before assigning timer->private_data. This creates a brief window where the timer is visible on the global list while its private_data pointer is still NULL . Concurrent reade...

EUVD-2026-93293

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: trace PCM open only after assigning a stream Stream assignment can fail when hardware streams are exhausted. Move the tracepoint after the NULL check because its payload accesses the assigned stream tag. Detected by...

CVE-2026-98308

The Linux kernel contains a vulnerability in the ALSA: hda driver where a tracepoint was incorrectly positioned. The issue occurs because stream assignment can fail when hardware streams are exhausted; however, the existing tracepoint payload attempted to access the assigned stream tag before a N...
