Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. Linux kernel is vulnerable to a denial of service. An attacker could exploit this vulnerability to force a NULL pointer dereference on the Linux kernel via kvm_mmu_invpcid_gva to trigger a denial of service.
