CVE-2024-56550

In the Linux kernel, the following vulnerability has been resolved:

s390/stacktrace: Use break instead of return statement

archstackwalkusercommon() contains a return statement instead of a break statement in case storeip() fails while trying to store a callchain entry of a user space process. This may lead to a missing pagefaultenable() call.

If this happens any subsequent page fault of the process won't be resolved by the page fault handler and this in turn will lead to the process being killed.

Use a break instead of a return statement to fix this.
