This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-190"],"references":["http://packetstormsecurity.com/files/167345/libxml2-xmlBufAdd-Heap-Buffer-Overflow.html","http://packetstormsecurity.com/files/169825/libxml2-xmlParseNameComplex-Integer-Overflow.html","https://gitlab.gnome.org/GNOME/libxml2/-/commit/2554a2408e09f13652049e5ffb0d26196b02ebab","https://gitlab.gnome.org/GNOME/libxml2/-/commit/6c283d83eccd940bcde15634ac8c7f100e3caefd","https://gitlab.gnome.org/GNOME/libxml2/-/tags/v2.9.14"],"products":["debian:debian_linux","fedoraproject:fedora","netapp:active_iq_unified_manager","netapp:clustered_data_ontap","netapp:clustered_data_ontap_antivirus_connector","netapp:h300s_firmware","netapp:h410c_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware","netapp:manageability_software_development_kit","netapp:ontap_select_deploy_administration_utility","netapp:smi-s_provider","netapp:snapdrive","netapp:snapmanager","netapp:solidfire_\\&_hci_management_node","oracle:zfs_storage_appliance_kit","xmlsoft:libxml2","xmlsoft:libxslt"],"source":"nvd","synced_at":"2026-10-19T21:30:03.577988018+00:00"},"epss":{"cve":"CVE-2022-29824","score":0.03753,"percentile":0.89805,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
