CVE-2014-2706: Race Condition

First published: Wed Apr 02 2014(Updated: )

A Linux kernel built with a Generic IEEE 802.11 Networking Stack (CONFIG_MAC80211) is vulnerable to a crash caused by a race condition in frame transmission path and station wakeup event, in case when it's sleeping. The crash occurs because, mac80211 stack buffers frames when the station is sleeping, and the same are transmitted upon the station's(STA) wakeup. At this point, a buffered TX frame list is being emptied, while a new frame is being added to the RX list. A remote unprivileged user/program could use this flaw to crash the system kernel, resulting in DoS.
