Attackers can send zero-length or 1-3 byte data payloads through a hostile implant session to trigger an out-of-bounds slice access in the vendored Binject library's BinaryMagic function, which propagates unrecovered through the operator gRPC interceptor chain and terminates the server process, affecting all connected operators.","categories":["Unclassified"],"product":"sliver","vendor":"BishopFox","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102507","source_modified_at":"2026-10-01T15:19:47.776Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"sliver","vendor":"BishopFox","versions":[{"status":"affected","version":"1.1.0","versionType":"semver","lessThanOrEqual":"1.7.7"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00184,"percentile":0.07586,"score_date":"2026-10-23"},"published_at":"2026-09-29T11:49:54.760Z","modified_at":"2026-10-01T15:19:47.776Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102507","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T15:19:47.776Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102507","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/h00die/sliver_1.7.7_DoS","tags":["exploit","technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/sliver-denial-of-service-via-pe-parser-slice-bounds-in-operator-rpc","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T17:56:49.436322Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T15:19:47.776Z","content_hash":"4f378c81130bd2b3599305e3603ea5b8ec52e780d24d886881f79caaa255d260"}}
