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.","state":0,"publishedAt":"2026-09-29T11:49:54.76+00:00","modifiedAt":"2026-10-01T15:19:47.776+00:00","affected":[{"ecosystem":"Vendor product","name":"sliver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"BishopFox\",\n                    \"product\": \"sliver\",\n                    \"packageURL\": \"pkg:github/BishopFox/sliver\",\n                    \"repo\": \"https://github.com/BishopFox/sliver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.1.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"1.7.7\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","score":5.7,"severity":"MEDIUM"}],"references":["https://github.com/h00die/sliver_1.7.7_DoS","https://www.vulncheck.com/advisories/sliver-denial-of-service-via-pe-parser-slice-bounds-in-operator-rpc"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102507","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102507","identifiers":["CVE-2026-102507"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
