Description:
A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an off-by-two error within the function "ieee80211_rx()" in net/ieee80211/ieee80211_rx.c. This can be exploited to cause a kernel panic by sending a specially crafted ieee80211 frame with the IEEE80211_STYPE_QOS_DATA flag set to an affected system.
The vulnerability is reported in versions prior to 2.6.23.
Solution:
Update to version 2.6.23.
