Description
An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values.
A denial of service problem was found in the Linux kernel's Kernel-based Virtual Machine (KVM) specific to PowerPC. In this flaw, a user with local access can confuse the host offline code, causing the guest to crash.
