Bug#729573: linux-image-3.2.0-4-amd64: [ath9k_htc] MAC address not properly updated

Mathy Vanhoef Thu, 14 Nov 2013 05:52:12 -0800

Package: src:linux
Version: 3.2.51-1
Severity: normal
Tags: security upstream


Dear Maintainer,

I found a bug in the ath9k_htc driver for Atheros WiFi dongles. When auser changes their MAC address, an attacker can retrieve the originalMAC address, which is a potential privacy risk. Details of the bug:http://www.mathyvanhoef.com/2013/11/unmasking-spoofed-mac-address.html

The ath9k driver does not appear to have this problem, there thehardware MAC address is set to one of the virtual interfaces.


Can a CVE ID be assigned to this?

- Mathy
