Detailed vulnerability description
The vulnerability allows a local attacker to cause DoS condition on the host system.
The weakness exists due to array access error. A local user on the guest system can send specially crafted software generated interrupts to vCPUS that use the MMIO register GICD_SGIR (GICv2) or System Register ICC_SGI1R (GICv3) and cause the hypervisor to crash.
Successful exploitation of the vulnerability results in denial of service.
