What is "nt!se - General Security Allocations"?It seems leaking memory

hh12345 1 Reputation point

There is something leaking memory on my computer, and it's not caused by any app launched by myself, because when I closed all apps, the memory is still occupied. The paged pool is increased.
I tried to use PoolMon.exe to figure out the reason, then I found the pool tag "Se", and its source is "nt!se", description is General Security Allocations, which occupied the most memory

What is it? And why did this happen?
