{"id":"CVE-2026-25061","summary":"tcpflow has TIM Element OOB Write in wifipcap","details":"tcpflow is a TCP/IP packet demultiplexer. In versions up to and including 1.61, wifipcap parses 802.11 management frame elements and performs a length check on the wrong field when handling the TIM element. A crafted frame with a large TIM length can cause a 1-byte out-of-bounds write past `tim.bitmap[251]`. The overflow is small and DoS is the likely impact; code execution is potential, but still up in the air. The affected structure is stack-allocated in `handle_beacon()` and related handlers. As of time of publication, no known patches are available.","aliases":["GHSA-q5q6-frrv-9rj6"],"modified":"2026-05-28T04:11:25.174140217Z","published":"2026-01-29T21:42:47.013Z","database_specific":{"cwe_ids":["CWE-787"],"unresolved_ranges":[{"extracted_events":[{"last_affected":"1.61"}],"source":"AFFECTED_FIELD"}],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25061.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2026/02/msg00014.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25061.json"},{"type":"ADVISORY","url":"https://github.com/simsong/tcpflow/security/advisories/GHSA-q5q6-frrv-9rj6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25061"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/simsong/tcpflow","events":[{"introduced":"0"},{"last_affected":"c98938b320f5aba5e40312e1ad6db9fe55733909"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.6.1"}],"cpe":"cpe:2.3:a:digitalcorpora:tcpflow:*:*:*:*:*:*:*:*","source":"CPE_RANGE"}}],"versions":["tcpflow-1.6.1","tcpflow-1.5.2","tcpflow-1.5.1","tcpflow-1.5.0","push","tcpflow-1.4.5","tcpflow-1.4.3","tcpflow-1.4.2","tcpflow-1.4.1","tcpflow-1.4.0","tcpflow-1.3.0","tcpflow-1.2.9","tcpflow-1.2.7","tcpflow-1.2.5"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-25061.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P"}]}
