An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.","published":"2022-02-11T18:15:11.000Z","lastModified":"2026-06-17T04:20:07.000Z","status":"Analyzed","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-190","CWE-191"],"affected":["linux/linux kernel","netapp/h410c firmware","netapp/h300s firmware","netapp/h500s firmware","netapp/h700s firmware","netapp/h300e firmware","netapp/h500e firmware","netapp/h700e firmware","netapp/h410s firmware"],"epss":{"score":0.25151,"percentile":0.9793,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2024-08-21","dueDate":"2024-09-11","knownRansomwareCampaignUse":"Unknown","notes":"Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.\nThis vulnerability affects a common open-source component, third-party library, or a protocol used by different products.
