Other heap content would be overwritten if the specified size was too small.\n\nUsers with access to the mpr, mps or mpt device node may overwrite heap data, potentially resulting in privilege escalation.  Note that the device node is only accessible to root and members of the operator group.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-787","CWE-122"],"references":["https://security.freebsd.org/advisories/FreeBSD-SA-22:06.ioctl.asc","https://security.netapp.com/advisory/ntap-20240419-0002/","https://security.freebsd.org/advisories/FreeBSD-SA-22:06.ioctl.asc","https://security.netapp.com/advisory/ntap-20240419-0002/"],"products":["freebsd:freebsd"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2022-23086","score":0.00447,"percentile":0.38864,"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).
