In version 1.2.9 and earlier, FastNetMon's IPv6 top-talkers screen-draw thread in draw_table_ipv6() in src/fastnetmon_logic.cpp iterates ipv6_host_counters.average_speed_map without holding counter_map_mutex while recalculate_speed() inserts new keys and may rehash the same map. The race requires networks_list to include the targeted IPv6 range. It causes confirmed undefined behavior under load; a process crash is plausible but was not observed, so reliable denial of service has not been established. No fixed release is available as of this review.","score":5.9,"severity":"medium","published":"2026-11-05T22:29:26.943Z","modified":"2026-11-09T17:41:09.393Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"pavel-odintsov","name":"fastnetmon","platforms":[],"versions":[{"version":"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-2026-92694"}],"remediation":[],"references":["https://github.com/pavel-odintsov/fastnetmon/security/advisories/GHSA-phrw-2q76-5m7h","https://github.com/pavel-odintsov/fastnetmon/pull/1087","https://github.com/pavel-odintsov/fastnetmon/commit/1294724ea931dc78fe545360f2193398bba35381"],"sources":[{"name":"CVE","id":"CVE-2026-92694","modified":"2026-11-09T17:41:09.393Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-92694"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9}],"sourceAffected":[],"observedAt":"2026-11-09T17:51:42.321Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T02:45:32.518Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-06T00:45:40.682Z","attemptedAt":"2026-11-06T00:45:40.682Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-06T00:45:40.434Z","attemptedAt":"2026-11-06T00:45:40.434Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-06T00:45:43.230Z","attemptedAt":"2026-11-06T00:45:43.230Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-06T00:45:40.605Z","attemptedAt":"2026-11-06T00:45:40.605Z"}],"evidence":[{"source":"NVD","id":"CVE-2026-92694","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92694","modified":"2026-11-05T23:17:02.257","score":5.9,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-11-06T00:45:40.682Z"},{"source":"ENISA EUVD","id":"EUVD-2026-117832","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-117832","modified":"Nov 5, 2026, 10:29:26 PM","score":5.9,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-11-06T00:45:43.230Z"}],"aiSummary":{"text":"FastNetMon versions 1.2.9 and earlier have a race condition due to iterating ipv6_host_counters without a lock, potentially causing a process crash.
