CVE-2024-56550
s390/stacktrace: Use break instead of return statement
Summary
s390/stacktrace: Use break instead of return statement
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
s390/stacktrace: Use break instead of return statement
arch_stack_walk_user_common() contains a return statement instead of a
break statement in case store_ip() fails while trying to store a callchain
entry of a user space process.
This may lead to a missing pagefault_enable() 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.
