Summary
In the Linux kernel, the following vulnerability has been resolved: arm64/ptrace: Fix stack-out-of-bounds read in regs_get_kernel_stack_nth() KASAN reports a stack-out-of-bounds read in regs_get_kernel_stack_nth().

Use READ_ONCE_NOCHECK() helper to silence the KASAN check for this case. [will: Use '*addr' as the argument to READ_ONCE_NOCHECK()]
