Description:
A weakness has been reported in the Linux Kernel, which can be exploited by malicious, local users to bypass certain security restrictions.
The weakness is caused due to an error when processing the signals sent by a child process created via the "clone()" system call and the "CLONE_PARENT" flag, which can be exploited to e.g. kill a parent process with higher privileges.
Successful exploitation e.g. requires that the privileged parent process launches user supplied applications as child processes.
