Description
In the Linux kernel, the following vulnerability has been resolved:
uprobes/x86: Harden uretprobe syscall trampoline check
Jann reported a possible issue when trampoline_check_ip returns
address near the bottom of the address space that is allowed to
call into the syscall if uretprobes are not set up:

Though the mmap minimum address restrictions will typically prevent
creating mappings there, let's make sure uretprobe syscall checks
for that.
