{"id":"CVE-2025-51006","details":"Within tcpreplay's tcprewrite, a double free vulnerability has been identified in the dlt_linuxsll2_cleanup() function in plugins/dlt_linuxsll2/linuxsll2.c. This vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes the cleanup routine multiple times on the same memory region. By supplying a specifically crafted pcap file to the tcprewrite binary, a local attacker can exploit this flaw to cause a Denial of Service (DoS) via memory corruption.","modified":"2026-05-18T05:59:33.507355002Z","published":"2025-09-22T00:00:00Z","related":["openSUSE-SU-2025:15728-1","openSUSE-SU-2025:20119-1"],"database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/51xxx/CVE-2025-51006.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/51xxx/CVE-2025-51006.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-51006"},{"type":"REPORT","url":"https://github.com/appneta/tcpreplay/issues/926"},{"type":"PACKAGE","url":"https://github.com/sy460129/CVE-2025-51006"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/appneta/tcpreplay","events":[{"introduced":"0"},{"last_affected":"0ba7d17fcb9ddedf61168f99c249b30731310d4e"}],"database_specific":{"source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"4.5.1"}],"cpe":"cpe:2.3:a:broadcom:tcpreplay:4.5.1:*:*:*:*:*:*:*"}}],"versions":["v4.5.1","v4.4.3","v4.2.6","v4.1.2","v4.1.1","v4.1.1-beta3","v4.1.1-beta2","v4.1.0","v4.1.0beta2","v4.1.0beta1","v4.0.5","v4.0.5beta3","v4.0.5beta2","v4.0.5beta1","v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0.0","v4.0.0beta2","v4.0.0beta1","v3.4.4","v3.4.3","v3.4.2"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-51006.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
