I also doubt that anyone is still using SGML catalogs at all.\"", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2025-8732" } ], "release_date": "2025-08-08T16:32:00Z", "remediations": [ { "category": "vendor_fix", "date": "2026-04-09T10:43:35.933317Z", "details": "Details on how to apply the fix are available at: https://cve.tuxcare.com/els/releases/CLSA-2026:1775731413", "product_ids": [ "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64" ], "url": "https://cve.tuxcare.com/els/releases/CLSA-2026:1775731413" } ], "scores": [ { "cvss_v3": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "LOW", "baseScore": 3.3, "baseSeverity": "LOW", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L", "version": "3.1" }, "products": [ "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "AlmaLinux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "AlmaLinux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.i686", "Rocky Linux-9.6:libxml2-devel-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:libxml2-static-0:2.9.13-12.el9_6.tuxcare.els3.x86_64", "Rocky Linux-9.6:python3-libxml2-0:2.9.13-12.el9_6.tuxcare.els3.x86_64" ] } ], "threats": [ { "category": "impact", "details": "Low" } ] } ] }
