CVE-2026-98345

The Linux kernel contains a vulnerability within the cfg80211 component, specifically in the cfg80211_classify8021d() function. The issue occurs when a frame mimicking an IP packet is transmitted but is too short, causing the DS field to be read incorrectly. This leads to an uninit-value error as...

CVE-2026-98344

The Linux kernel contains a vulnerability in the dmaengine component involving a device kref underflow in dma_chan_put(). The issue occurs because dma_chan_get() only increments the chan->device->ref on the slow path, while dma_chan_put() drops the reference unconditionally. This causes a m...

EUVD-2026-93328

In the Linux kernel, the following vulnerability has been resolved: dmaengine: fix use-after-free in dmachanput and dmareleasechannel When dmadeviceput drops the last reference on chan-device-ref, dmadevicerelease runs and may free the dmadevice along with its channels. dmachanput then still read...

EUVD-2026-93329

In the Linux kernel, the following vulnerability has been resolved: dmaengine: Fix device kref underflow in dmachanput dmachanget takes chan-device-ref only on the slow path: / no kref on fast path / if chan-clientcount modulegetowner; chan-clientcount++; return 0; if !trymodulegetowner return...

CVE-2026-98343

The Linux kernel contains a use-after-free vulnerability in the dmaengine component, specifically within the dma_chan_put() and dma_release_channel() functions. The issue occurs because dma_device_put() can drop the last reference on chan->device->ref, triggering dma_device_release() and fr...

CVE-2026-98342

The Linux kernel dmaengine component contains a vulnerability where dma_device_release() unlinks a device using list_del_RCU() and subsequently frees it without ensuring a grace period. This allows concurrent RCU readers in dma_issue_pending_all() to access the device after it has been freed, pot...

EUVD-2026-93327

In the Linux kernel, the following vulnerability has been resolved: dmaengine: wait for RCU readers before releasing dmadevice dmaissuependingall walks the dmadevicelist with listforeachentryrcu under rcureadlock. dmadevicerelease unlinks the device with listdelrcu and then calls...

EUVD-2026-93326

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't free driver-owned scan requests When an interface goes down while a scan is running, cfg80211 completes the scan towards userspace and frees the scan request. However, the driver can be convinced that it own...

CVE-2026-98341

A Use-After-Free (UAF) vulnerability exists in the Linux kernel within the wifi: cfg80211 component. When a wireless interface goes down during an active scan, cfg80211 completes the scan and frees the scan request; however, because cancellation is asynchronous, the driver may still believe it ow...

CVE-2026-98340

The Linux kernel contains a vulnerability in the cfg80211 WiFi stack where the __cfg80211_bss_update() function incorrectly groups hidden BSSes**. Specifically, it may group a probe response for an unknown BSS with an existing entry that lacks beacon elements, creating a group withou...

EUVD-2026-93325

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: only group hidden BSSes with beacon entries When a probe response for an unknown BSS comes in, cfg80211bssupdate looks for an existing entry with the same BSSID and a hidden zero-length or NUL-filled SSID, and if ...

CVE-2026-98339

The Linux kernel contains a vulnerability in the cfg80211 component where the cfg80211_update_assoc_bss_entry() function fails to properly filter by BSS type when removing stale entries. When an associated Access Point switches to a channel with an existing BSS entry, the system fails to remove e...

CVE-2026-98338

The Linux kernel contains a race condition in the cfg80211 wireless subsystem when joining an IBSS . The issue occurs because the system previously recorded only the BSSID/channel and performed a lookup later; however, a new scan with NL80211_SCAN_FLAG_FLUSH could remove the BSS entry before proc...

EUVD-2026-93324

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't filter by BSS type when removing stale entries When an assoc AP switches to a channel that already has a BSS entry, cfg80211updateassocbssentry removes that entry before rehashing the real one, since the two...

EUVD-2026-93323

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: ibss: ref BSS entry for joined event When the IBSS is joined, we only record the BSSID/channel in the event and look up the BSS entry when processing it. However, that's racy, e.g. a new scan with...

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/...

EUVD-2026-93322

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...

EUVD-2026-93321

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...

EUVD-2026-93320

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...
