Repeated rapid KVM host crash/reboot cycles indicating shadow MMU UAF exploitation

Detects recurring kernel panic or oops events on KVM hosts occurring in rapid succession, typically within a 5-minute window. This behavioral pattern is consistent with an attacker repeatedly exploiting a race condition, such as a use-after-free (UAF) in the KVM shadow MMU, to trigger a persistent host denial-of-service.
