- 漏洞描述
- 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 3.8.9之前的版本中的kernel/events/core.c中的perf_swevent_init函数中存在漏洞。由于Linux内核无法检查用户空间传递的attr.config的所有64位，导致sw_perf_event_destroy()中的perf_swevent_enabled数组越界访问。在使用PERF_EVENTS支持编译的系统上，攻击者可以发送特制的perf_event_open()调用以在具有root权限的系统上执行任意代码。
