CVE-2019-5108

Priority
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.
Ubuntu-Description
Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel
when used as an access point would send IAPP location updates for stations
before client authentication had completed. A physically proximate attacker
could use this to cause a denial of service.
