Detailed vulnerability description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the Linux kernel before 3.10 on the ARM platform, when KVM is used, allows host OS users to cause a denial of service (NULL pointer dereference, OOPS, and host OS crash) or possibly have unspecified other impact by omitting vCPU initialization before a KVM_GET_REG_LIST ioctl call. A remote attacker can perform a denial of service (DoS) attack.
