A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free. We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.\n\nFIRST-EPSS: 0.000420000\nNVD-IS: 5.9\nNVD-ES: 1.8", "creation_timestamp": "2023-12-18T06:40:20.000000Z"} 2023-12-18T06:40:20+00:00 https://vulnerability.circl.lu/sighting/06df5a4f-f1f8-42a8-a8fc-7d67c1c87851/export 2026-05-27T16:45:13.620918+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "06df5a4f-f1f8-42a8-a8fc-7d67c1c87851", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-4206", "type": "published-proof-of-concept", "source": "https://t.me/HackerArsenal/171", "content": "#exploit\n1.
