Doc Text:
A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path.

Description Marian Rehak 2019-08-21 12:54:03 UTC
There is heap-based buffer overflow in marvell wifi chip driver in Linux kernel while parsing vendor specific infomormational attributes allows an attacker on the same wifi physical network segment to cause a denial of service(system crash) or possibly execute arbitrary code.

Comment 10 Wade Mealing 2019-11-26 05:07:50 UTC
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1776607]

Comment 14 Wade Mealing 2019-11-26 05:35:37 UTC
Mitigation:

At this time there is no mitigation to the flaw, if you are able to disable wireless and your system is able to work this will be a temporary mitigation until a kernel update is available for installation.

Comment 17 Justin M. Forbes 2019-11-26 14:04:17 UTC
This was fixed for Fedora with the 5.2.17 stable kernel update.
