kernel: mm: prevent derefencing NULL ptr in pfn_section_valid()
A flaw was found in the Linux kernel. This flaw allows a local user to cause a Denial of Service DoS by crashing the system. A race condition during memory section deactivation in the memory management subsystem can lead to a null pointer dereference in the pfnsectionvalid function due to a missi...
