Description Marcus Meissner 2019-12-30 13:12:58 UTC

CVE-2019-5108

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.

Comment 1 Marcus Meissner 2019-12-30 13:17:19 UTC

i could not spot an upstream commit for it yet.

Comment 3 Miroslav Beneš 2020-01-31 11:45:52 UTC

Coincidentally I checked yesterday and found 3e493173b784 ("mac80211: Do not send Layer 2 Update frame before authorization"). However, someone has to ensure it is really the fix.

Al, Michal?
