Developers of the Linux kernel have patched a bug that allowed attackers to
remotely crash a machine by sending it malicious Wi-Fi signals.

The flaw in the delBA handling of mac80211 has been fixed in version 2.6.32,
the latest stable release of the Linux kernel. Various distributions of the
open-source operating system have already acknowledged the issue and are
expected to push out updates soon. Based on developer notes on the official
Linux website, the vulnerability appears to have been introduced in February.
