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.
A NULL pointer dereference security flaw was found in the Linux kernel in the vcpu_scan_ioapic() function in arch/x86/kvm/x86.c. This allows local users with certain privileges to cause a denial of service via a crafted system call to the KVM subsystem.
