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review.","score":8.2,"severity":"high","published":"2026-11-05T22:32:35.388Z","modified":"2026-11-06T17:42:09.687Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"pavel-odintsov","name":"fastnetmon","platforms":[],"versions":[{"version":"<= 1.2.9","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-92693"}],"remediation":[],"references":["https://github.com/pavel-odintsov/fastnetmon/security/advisories/GHSA-jmjw-392h-4g93","https://github.com/pavel-odintsov/fastnetmon/commit/1da80df73620c6d0aa4462e9611e65047529b12a"],"sources":[{"name":"CVE","id":"CVE-2026-92693","modified":"2026-11-06T17:42:09.687Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-92693"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","score":8.2}],"sourceAffected":[],"observedAt":"2026-11-06T18:52:08.389Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T22:45:30.999Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-06T00:40:33.272Z","attemptedAt":"2026-11-06T00:40:33.272Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-06T00:40:33.272Z","attemptedAt":"2026-11-06T00:40:33.272Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-06T00:40:32.673Z","attemptedAt":"2026-11-06T00:40:32.673Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-06T00:40:32.031Z","attemptedAt":"2026-11-06T00:40:32.031Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-117871","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-117871","modified":"Nov 5, 2026, 10:32:35 PM","score":8.2,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","checkedAt":"2026-11-06T00:40:32.673Z"},{"source":"NVD","id":"CVE-2026-92693","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92693","modified":"2026-11-05T23:17:02.073","score":8.2,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","checkedAt":"2026-11-06T00:40:33.272Z"}],"aiSummary":{"text":"FastNetMon versions 1.2.9 and earlier have an out-of-bounds read weakness in the shared packet parser when handling IPv6 Fragment headers without bounds checks.
