{"affected":[{"product":"fastnetmon","source":"CNA: GitHub_M","vendor":"pavel-odintsov","versions":[{"status":"affected","version":"<= 1.2.9"}]}],"cveId":"CVE-2026-92693","cwes":["CWE-125"],"description":"FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, parse_raw_packet_to_simple_packet_full() in src/simple_packet_parser_ng.cpp dereferences ipv6_extension_header_fragment_t when IpProtocolNumberIPV6_FRAG is present without first verifying that the eight-byte Fragment header remains. A crafted sFlow v5 RAW_PACKET_HEADER record can remotely reach this shared parser with the Fragment bytes omitted, causing an unauthenticated remote out-of-bounds read. The supplied harness detects the read under AddressSanitizer, but the advisory does not establish a production process crash. No fixed release is available as of this review.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.2,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"}],"modifiedAt":1793917955388,"publishedAt":1793917955388,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/pavel-odintsov/fastnetmon/security/advisories/GHSA-jmjw-392h-4g93"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pavel-odintsov/fastnetmon/commit/1da80df73620c6d0aa4462e9611e65047529b12a"}],"remediation":[],"revision":"5899ba45e802a7197cc11d72e0ead8c8a17d7f8c290c1fdd9717d9b2cfc6921e","sources":[{"modifiedAt":1793917955388,"name":"CNA: GitHub_M","retrievedAt":1793920186789,"url":"https://www.cve.org/CVERecord?id=CVE-2026-92693"}],"ssvc":null,"status":"published","title":"FastNetMon: IPv6 Fragment header dereferenced without bounds check in shared packet parser","updatedAt":1793920186789}
