Description Johannes Segitz 2019-12-13 10:24:33 UTC

An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where
an attacker could trigger 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.

The description says 2.6, but I assume that it affects hostapd until 018edec9b2bd3db20605117c32ff79c1e625c432 where IAPP support is remove. So Leap 15.1 and Factory affected
