Vulnerability Title
N/A
Vulnerability Description
The kill_something_info function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via a kill command.

Linux Kernel '/signal.c'本地拒绝服务漏洞
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的kernel/signal.c文件中的kill_something_info函数在处理发送给PID -1的信号时没有考虑PID命名空间，这允许本地用户绕过预期的命名空间隔离，通过kill命令向命名空间中的所有进程发送任意信号。
