Vulnerability Title
MadWifi "net80211/ieee80211_wireless.c文件"远程拒绝服务漏洞
Vulnerability Description
MadWifi全称是Multiband Atheros Driver for Wifi，是使用Atheros系列芯片的802.11a/b/g无线网卡在Linux下的驱动程序。 受限的本地用户可以对驱动的ieee80211_ioctl_getwmmparams执行非特权I/O控制调用，这个函数未经正确验证便接受了用户的数组索引，仅检查了用户所提供的数组是否小于最大的值，但没有检查是否小于0，这样本地攻击者就可以指定很大的负数值绕过检查，导致数组引用中出现错误。
