Description:
A vulnerability has been reported in KVM, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the "kvm_arch_vcpu_ioctl_set_sregs()" function. This can be exploited to trigger a NULL-pointer dereference and potentially crash an affected system by setting the CR3 register to an invalid value via a specially crafted "KVM_SET_SREGS" call.
The vulnerability is reported in version kvm-84. Other versions may also be affected.
