CVE-2026-68404

The CVE-2026-68404 entry describes a race in the Linux kernel’s cfg80211 wireless subsystem during socket owner autodisconnect. The root cause is a work item (disconnect_wk) queued after cancellation, which could lead to a system crash (DoS) if NETLINK_URELEASE observers reach the wdev list. The ...
