Loading vulnerability…
In the Linux kernel 2.6.28 and earlier, the clone() system call can be abused by a local, unprivileged user to send arbitrary signals to a parent process from an unprivileged child process. An attacker can create an additional child process using the CLONE_PARENT flag so that the new process has the same parent as the caller, and then cause this new process to exit; this enables signal delivery to the parent in a way that bypasses expected privilege/relationship checks.
