The\nnetdevice notifier shuts down the socket before calling kthread_stop(), so\nthe task_struct can be freed before kthread_stop() gets its reference.\n\nCreate the listener in a stopped state and hold an extra task_struct\nreference until kthread_stop_put() completes. Also stop and release\nlisteners before freeing their interface records during TCP teardown.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":210912,"id":"CVE-2026-98112","ts":1790349115077,"field":"cvss","old":null,"new":"7.8"},{"seq":210911,"id":"CVE-2026-98112","ts":1790349115077,"field":"severity","old":"none","new":"high"}]}
