{"id":"CVE-2019-5108","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-5108","generatedAt":"2026-11-05T02:25:55.661Z","title":"An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3.","description":"An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.","published":"2019-12-23T19:15:12.000Z","lastModified":"2026-06-17T02:37:09.000Z","status":"Modified","sourceIdentifier":"talos-cna@cisco.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-440","CWE-287"],"affected":["linux/linux kernel","debian/debian linux","canonical/ubuntu linux","netapp/active iq unified manager","netapp/cloud backup","netapp/data availability services","netapp/e-series santricity os controller","netapp/hci management node","netapp/solidfire","netapp/steelstore cloud integrated storage","netapp/a700s firmware","netapp/h610s firmware","netapp/8300 firmware","netapp/8700 firmware","netapp/a400 firmware","oracle/sd-wan edge"],"epss":{"score":0.10114,"percentile":0.9565,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 10.1%, higher than 96% of all known CVEs.
