CVE-2026-68414

CVE-2026-68414 affects the Linux kernel cfg80211 Wi‑Fi subsystem. When unregistering a wiphy, a queued or running cfg80211_sched_scan_results_wk can reference freed rdev state because sched_scan_res_wk is not drained during unregister. This allows a use-after-free scenario as the worker crosses t...

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 ...

CVE-2026-68357

The CVE pertains to the Linux kernel watchdog subsystem. It describes a use-after-free (UAF) that occurs when a watchdog governor is unregistered and the currently active governor is also the default_gov. In this case, the default_gov is not cleared, causing: (1) new watchdog devices to inherit a...

CVE-2026-68301

The CVE-2026-68301 entry details a Linux kernel net: hsr memory leak where, on slave unregistration, VLAN IDs synced to the slave (including VID 0) are not deleted, leaving vlan_info/vlan_vid_info refs and causing a leak when the slave is destroyed. The fix adds vlan_vids_del_by_dev(port->dev,...

CVE-2026-68290

CVE-2026-68290 concerns the Linux kernel RDS TCP implementation. A race condition during network namespace teardown can occur when a concurrent sysctl write dereferences a freed per-netns listen socket, due to rds_tcp_exit_net() freeing the socket before the per-netns sysctl table is unregistered...

CVE-2026-68283

The CVE-2026-68283 issue is in the Linux kernel tracing subsystem. A use-after-free arises because freeing of event_trigger_data was moved to a kthread and synchronized later via tracepoint_synchronize_unregister(), breaking prior inline synchronization in trigger_data_free(). As a result, after ...
