This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).","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-122"],"references":["https://access.redhat.com/errata/RHSA-2026:21333","https://access.redhat.com/errata/RHSA-2026:28236","https://access.redhat.com/errata/RHSA-2026:48818","https://access.redhat.com/security/cve/CVE-2026-9149","https://bugzilla.redhat.com/show_bug.cgi?id=2460380"],"products":["opensuse:libsolv","redhat:enterprise_linux","redhat:hardened_images","redhat:openshift_container_platform","redhat:satellite","redhat:update_infrastructure"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-9149","score":0.00312,"percentile":0.24149,"date":"2026-10-31"},"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).
