Every read is therefore performed at an offset the file itself chose, against a buffer whose extent the loader does not know. A resource that declares more data than it contains is read past its end, and an offset stored in the file is turned into a pointer without being bounded.\n\n\n\nThis is a distinct defect from GHSA-hgcj-22cg-4hfv, which was an underflowed glyph count. It needs no underflow and no wrapped multiply: a perfectly well-formed, narrow glyph range reaches it.","state":0,"publishedAt":"2026-10-20T14:52:45.765+00:00","modifiedAt":"2026-10-20T15:26:36.082+00:00","affected":[{"ecosystem":"Vendor product","name":"GUIX","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Eclipse Foundation\",\n                    \"product\": \"Eclipse ThreadX - GUIX\",\n                    \"packageName\": \"GUIX\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"6.5.1.202602a\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"6.5.2.202603\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/eclipse-threadx/guix/security/advisories/GHSA-m779-jvp3-pmqr"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92446","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92446","identifiers":["CVE-2026-92446"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
