uprobes/x86: Use proper mm_struct in __in_uprobe_trampoline
Overview
Description

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.
