"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: Fix IRQ injection with SIGP Stop and Store Status\n\nWhen __inject_sigp_stop() is called for a Stop and Store Status\noperation, if the vCPU is running, the interrupt is marked as pending\nand the status is stored by the thread performing the KVM_RUN IOCTL.\n\nIf the vCPU is already stopped, the status is stored immediately.\n\nStoring the status means writing into userspace, which might fault, and\n__inject_sigp_stop() is called from do_inject_vcpu() which in turn is\nalways called holding a spinlock, which is obviously an issue.\n\nFix this by returning -EWOULDBLOCK from __inject_sigp_stop(), and\nadding a bool flag to indicate whether a store status is needed. The\ncallers of do_inject_vcpu() are modified to pass the pointer to the\nbool flag; whenever a Store Status operation is needed, the callers can\nnow perform it outside the spinlock.\n\nOpportunistically refactor kvm_s390_set_irq_state() to use\nscoped_guard() and __free().\n\n[ Added Fixes tag while picking -- Claudio ]"
