CVE-2018-19407

Priority
Description
The vcpu_scan_ioapic function in arch/x86/kvm/x86.c in the Linux kernel
through 4.19.2 allows local users to cause a denial of service (NULL
pointer dereference and BUG) via crafted system calls that reach a
situation where ioapic is uninitialized.
Ubuntu-Description
Wei Wu discovered that the KVM implementation in the Linux kernel did not
properly ensure that ioapics were initialized. A local attacker could use
this to cause a denial of service (system crash).
