Linux Kernel could allow a local authenticated attacker to execute arbitrary code on the system, caused by a flaw in the kvm_s390_guest_sida_op function in the arch/s390/kvm/kvm-s390.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain unauthorized memory write access to execute arbitrary code on the system.
