A theme id at or past the theme count declared by the resource gets a buffer of zero bytes. The load pass then walks past the end of the theme table, takes whatever follows as a theme header, and writes a `GX_THEME` and its tables into that zero-byte buffer.","evidence":"cve:CVE-2026-102729","products":[{"name":{"value":"GUIX","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-102729","aliases":["CVE-2026-102729"],"metrics":[{"format":"CVSS","cvssV4_0":{"Safety":"NOT_DEFINED","version":"4.0","Recovery":"NOT_DEFINED","baseScore":5.9,"Automatable":"NOT_DEFINED","attackVector":"LOCAL","baseSeverity":"MEDIUM","valueDensity":"NOT_DEFINED","vectorString":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","exploitMaturity":"NOT_DEFINED","providerUrgency":"NOT_DEFINED","userInteraction":"PASSIVE","attackComplexity":"LOW","attackRequirements":"PRESENT","privilegesRequired":"NONE","subIntegrityImpact":"NONE","vulnIntegrityImpact":"HIGH","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"LOW","vulnerabilityResponseEffort":"NOT_DEFINED"},"scenarios":[{"lang":"en","value":"GENERAL"}]}],"affected":[{"vendor":"Eclipse Foundation","product":"GUIX","versions":[{"status":"affected","version":"0","versionType":"semver","lessThanOrEqual":"6.5.1.202602a"},{"status":"unaffected","version":"6.5.2.202603"}],"defaultStatus":"unaffected"}],"modified":"2026-09-29T18:26:36.721Z","provider":"cve","references":["https://github.com/eclipse-threadx/guix/security/advisories/GHSA-372w-c338-xj8p"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102729","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T18:25:51.730585Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T18:26:36.721Z"}}],"cna":{"orgId":"e51fbebd-6053-4e49-959f-1b94eeb69a2c","shortName":"eclipse","dateUpdated":"2026-09-29T17:58:45.234Z"}}},"related_cves":[{"value":"CVE-2026-102729","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3896,"next_before":3896}
