In the Linux kernel, the following vulnerability has been resolved:
uprobes/x86: Use proper mm_struct in __in_uprobe_trampoline
In the unregister path we use __in_uprobe_trampoline check with
current->mm for the VMA lookup, which is wrong, because we are
in the tracer context, not the traced process.
Add mm_struct pointer argument to __in_uprobe_trampoline and
changing related callers to pass proper mm_struct pointer.
