Null pointer dereference in Windows Local Security Authority Subsystem Service (LSASS) allows an authorized attacker to deny service over a network.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
