Vulnerability Title
N/A
Vulnerability Description
The install_special_mapping function in mm/mmap.c in the Linux kernel before 2.6.37-rc6 does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application.

Linux kernel security_file_mmap函数限制绕过和空指针引用漏洞
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 2.6.37-rc6之前版本的mm/mmap.c文件中的install_special_mapping函数没有进行预期的security_file_mmap函数调用。本地用户可以借助特制的汇编语言应用程序绕过预设的mmap_min_addr限制并可能进行空指针解引用攻击。
