The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.

Linux kernel 'keyctl_session_to_parent'函数空指针应用错误漏洞
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 2.6.35.4以及早期版本中的security/keys/keyctl.c文件中的keyctl_session_to_parent函数认为存在某个父会话的密钥环，本地用户可以借助keyctl函数中的KEYCTL_SESSION_TO_PARENT参数调用导致拒绝服务（空指针解引用和系统崩溃），也可能引起其他未明影响。
