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.","state":0,"publishedAt":"2026-09-25T10:35:59.319+00:00","modifiedAt":"2026-10-19T09:14:04.636+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/smb/server/transport_tcp.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"3316a8fc840d82fad5efcf76ad0ea3f76fdca209\",\n                            \"lessThan\": \"40581f10c1e56238b157af5f260b8f9518a0cbc1\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"3316a8fc840d82fad5efcf76ad0ea3f76fdca209\",\n                            \"lessThan\": \"a506290f59e1c6ce9ac0a13158640bb8fee93471\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"fs/smb/server/transport_tcp.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.19\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.19\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.7\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/40581f10c1e56238b157af5f260b8f9518a0cbc1","https://git.kernel.org/stable/c/a506290f59e1c6ce9ac0a13158640bb8fee93471"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98112","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98112","identifiers":["CVE-2026-98112"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
