An off-by-one error can occur in the `gvs_tuple_is_normal` function in the `glib/gvariant-serialiser.c` file when doing an alignment padding check because the bounds check uses \u003e instead of \u003e=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary.","modified":"2026-08-11T14:14:17.680243253Z","published":"2026-08-11T13:55:26.657Z","upstream":["CVE-2026-58010","EUVD-2026-40312","GHSA-m7rp-473c-296x"],"database_specific":{"sources":[{"published":"2026-06-30T13:19:17.067Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-58010","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58010","database_specific":{"status":"Modified"},"id":"CVE-2026-58010","imported":"2026-08-11T06:49:24.010Z","modified":"2026-08-03T06:16:38.200Z"},{"imported":"2026-08-11T06:49:24.767Z","modified":"2026-08-03T06:31:41Z","published":"2026-06-30T15:30:44Z","url":"https://api.github.com/advisories/GHSA-m7rp-473c-296x","html_url":"https://github.com/advisories/GHSA-m7rp-473c-296x","id":"GHSA-m7rp-473c-296x"},{"modified":"2026-08-03T04:04:27Z","published":"2026-06-30T12:57:15Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-40312","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-40312","id":"EUVD-2026-40312","imported":"2026-08-11T06:49:24.407Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:49512"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-58010"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2492243"},{"type":"WEB","url":"https://github.com/advisories/GHSA-m7rp-473c-296x"},{"type":"WEB","url":"https://gitlab.gnome.org/GNOME/glib/-/issues/3915"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58010"}],"affected":[{"package":{"name":"Glib_jll","ecosystem":"Julia","purl":"pkg:julia/Glib_jll?uuid=7746bdde-850d-59dc-9ae8-88ece973131d"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.88.3+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1243.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"}]}
