{"id":"CVE-2026-102729","details":"`gx_binres_theme_load()` sizes its theme buffer for the theme it was asked for, and allocates it even when the resource holds no theme with that id. 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.","aliases":["GHSA-372w-c338-xj8p"],"modified":"2026-09-30T03:47:25.194529860Z","published":"2026-09-29T17:58:45.234Z","database_specific":{"cna_assigner":"eclipse","cwe_ids":["CWE-131","CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102729.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102729.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-372w-c338-xj8p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102729"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-threadx/guix","events":[{"introduced":"0"},{"last_affected":"52c1bb406843eb556d26dc28c65b13434f64e0ef"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"6.5.1.202602a"}],"source":"AFFECTED_FIELD"}}],"versions":["v6.5.1.202602a_rel","v6.5.1.202602_rel","v6.4.5.202504_rel","v6.4.3.202503_rel","v6.4.2_rel","v6.4.1_rel","v6.4.0_rel","v6.3.0_rel","v6.2.1_rel","v6.2.0_rel","v6.1.12_rel","v6.1.11_rel","v6.1.10_rel","v6.1.9_rel","v6.1.8_rel","v6.1.7_rel","v6.1.6_rel","v6.1.5_rel","v6.1.4_rel","v6.1.3_rel","v6.1_rel","v6.0.2_rel","v6.0.1_rel","v6.0_rel"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-102729.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
