DoS vulnerability remedied in Linux kernel
Author: JT Smith
Version 2.6.23 of the Linux kernel remedies a vulnerability in its 80211 WLAN code. A flaw in the function ieee80211_rx in net/ieee80211/ieee80211_rx.c can allow specially crafted WLAN frames to provoke a kernel panic if the IEEE80211_STYPE_QOS_DATA flag is set. Attackers need only send a manipulated frame to a PC or the victim's desktop.
