CVE-2026-31695

A flaw was found in the Linux kernel's virtwifi component. A local user can exploit a race condition during the unregistration of a virtwifi network device, where its parent pointer might refer to freed memory during ethtool operations. This use-after-free vulnerability can lead to system...

CVE-2026-43052

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check tdls flag in ieee80211tdlsoper When NL80211TDLSENABLELINK is called, the code only checks if the station exists but not whether it is actually a TDLS station. This allows the operation to proceed for non-TDL...
