Source: NVD (National Vulnerability Database)
Vulnerability Description
The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel before 4.3.4 does not properly use a semaphore, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls.

Linux kernel‘keyctl_read_key’函数本地拒绝服务漏洞
Source: CNNVD (China National Vulnerability Database)
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 4.3.4之前版本的security/keys/keyctl.c文件中的‘keyctl_read_key’函数中存在安全漏洞，该漏洞源于程序没有正确使用信号量。本地攻击者可借助特制的应用程序（利用keyctl_revoke和keyctl_read调用之间的竞争条件），利用该漏洞造成拒绝服务（空指针逆向引用和系统崩溃）。
