For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-22"],"references":["http://packetstormsecurity.com/files/161229/Kernel-Live-Patch-Security-Notice-LSN-0074-1.html","http://www.openwall.com/lists/oss-security/2021/01/13/2","http://www.openwall.com/lists/oss-security/2021/01/13/5","https://bugzilla.suse.com/attachment.cgi?id=844938","https://bugzilla.suse.com/show_bug.cgi?id=1178372"],"products":["debian:debian_linux","fedoraproject:fedora","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2020-28374","score":0.06642,"percentile":0.93874,"date":"2026-11-01"},"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).
