Descriptions
arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite loop) by making a H_CEDE hypercall during the existence of a suspended transaction.
arch/powerpc/kvm/book3s_hv_rmhandlers.S en el kernel de Linux hasta la versión 4.7 en plataformas PowerPC, cuando se encuentra habilitada CONFIG_KVM_BOOK3S_64_HV, permite a usuarios invitados del SO provocar una denegación de servicio (bucle infinito del SO anfitrión) haciendo una hiperllamada H_CEDE durante la existencia de una transacción suspendida.
Pengfei Wang discovered a race condition in the audit subsystem in the Linux kernel. A local attacker could use this to corrupt audit logs or disrupt system-call auditing. It was discovered that the powerpc and powerpc64 hypervisor-mode KVM implementation in the Linux kernel for did not properly maintain state about transactional memory. An unprivileged attacker in a guest could cause a denial of service in the host OS. Various other issues were also addressed.
