CVE-2022-2153 is a NULL pointer dereference in the Linux kernel KVM subsystem while setting a Hyper-V SynIC interrupt request. A misbehaving virtual machine monitor can cause writes to Hyper-V SynIC and synthetic timer model-specific registers, resulting in dereference of a NULL pointer in the KVM handling path. A local unprivileged host user can issue crafted KVM ioctl calls to trigger the fault.
