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-2026-93326

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 wifi: cfg80211: don't free driver-owned scan requests

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

The Linux kernel 's cfg80211 component is vulnerable to a Use-After-Free (UAF) in scan_done() when an interface goes down during an active scan. The vulnerability occurs because cfg80211 frees the scan request upon completion, but the driver may still believe it owns the request due to the asynch...

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...

CVE-2026-98339 wifi: cfg80211: don't filter by BSS type when removing stale entries

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...
