Vulnerability Title
N/A
Vulnerability Description
cfg80211 in net/wireless/scan.c in the Linux kernel 2.6.30-rc1 and other versions before 2.6.31-rc6 allows remote attackers to cause a denial of service (crash) via a sequence of beacon frames in which one frame omits an SSID Information Element (IE) and the subsequent frame contains an SSID IE, which triggers a NULL pointer dereference in the cmp_ies function. NOTE: a potential weakness in the is_mesh function was also addressed, but the relevant condition did not exist in the code, so it is not a vulnerability.

Linux Kernel cfg80211空指针引用拒绝服务漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux Kernel的net/wireless/scan.c文件中的cfg80211无线配置API没有正确地处理一系列信标帧。如果其中的一个帧遗漏了SSID信息元素(IE)而接下来的帧中包含有SSID IE，就会在cmp_ies函数中触发空指针引用，导致拒绝服务的情况。
