Problem Description:

Not all information in the struct ptrace_lwpinfo is + relevant for the state of any thread, and the kernel does + not fill the irrelevant bytes or short strings. Since the + structure filled by the kernel is allocated on the kernel + stack and copied to userspace, a leak of information of the + kernel stack of the thread is possible from the debugger.

Impact:

Some bytes from the kernel stack of the thread using + ptrace(PT_LWPINFO) call can be observed in userspace.
