NOTE: Someone in the security community disagrees that this is a vulnerability because the issue “is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.”","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","score":6.0},"cwes":["CWE-787"],"references":["https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=aa9f7d5172fac9bf1f09e678c35e287a40a7b7dd","https://github.com/torvalds/linux/commit/aa9f7d5172fac9bf1f09e678c35e287a40a7b7dd","https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html","https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html","https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html"],"products":["canonical:ubuntu_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:03:08.679916934+00:00"},"epss":{"cve":"CVE-2020-11565","score":0.00517,"percentile":0.44034,"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).
