Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> s390/stacktrace: Use break instead of return statement<br /> <br /> arch_stack_walk_user_common() contains a return statement instead of a<br /> break statement in case store_ip() fails while trying to store a callchain<br /> entry of a user space process.<br /> This may lead to a missing pagefault_enable() call.<br /> <br /> If this happens any subsequent page fault of the process won&amp;#39;t be resolved<br /> by the page fault handler and this in turn will lead to the process being<br /> killed.<br /> <br /> Use a break instead of a return statement to fix this.
