Vulnerability Description
The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM instruction, which allows local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter.

Linux kernel sk_run_filter函数信息泄露漏洞
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 2.6.36.2之前版本中的net/core/filter.c文件中的sk_run_filter函数没有检查某个内存地址是否经过初始化后再执行(1)BPF_S_LD_MEM或者(2)BPF_S_LDX_MEM指令。本地用户可以借助特制的socket过滤器从内核栈内存中获取潜在敏感信息。
