A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating. Both reproduce in the default configuration, in which `GX_SOFTWARE_DECODER_SUPPORT` is enabled.","state":0,"publishedAt":"2026-10-20T14:58:36.821+00:00","modifiedAt":"2026-10-20T15:21:42.8+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 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","score":6.1,"severity":"MEDIUM"},{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/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-pppm-h3g4-986x"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92454","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92454","identifiers":["CVE-2026-92454"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
