This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.ppc64le","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2026-0989","url":"https://www.suse.com/security/cve/CVE-2026-0989"},{"category":"external","summary":"SUSE Bug 1256804 for CVE-2026-0989","url":"https://bugzilla.suse.com/1256804"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.ppc64le","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":3.7,"baseSeverity":"LOW","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"products":["SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-2-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:libxml2-tools-2.9.7-150000.3.91.1.x86_64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","SUSE Linux Enterprise Micro 5.2:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.aarch64","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.ppc64le","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.s390x","openSUSE Leap 15.6:python3-libxml2-python-2.9.7-150000.3.91.1.x86_64"]}],"threats":[{"category":"impact","date":"2026-01-29T10:01:36Z","details":"moderate"}],"title":"CVE-2026-0989"}]}
