 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:KVM: s390: fix validity interception issue when gisa is switched offWe might run into a SIE validity if gisa has been disabled either via usingkernel parameter  kvm.use_gisa=0  or by setting the related sysfsattribute to N (echo N >/sys/module/kvm/parameters/use_gisa).The validity is caused by an invalid value in the SIE control block sgisa designation. That happens because we pass the uninitialized gisaorigin to virt_to_phys() before writing it to the gisa designation.To fix this we return 0 in kvm_s390_get_gisa_desc() if the origin is 0.kvm_s390_get_gisa_desc() is used to determine which gisa designation toset in the SIE control block. A value of 0 in the gisa designation disablesgisa usage.The issue surfaces in the host kernel with the following kernel message assoon a new kvm guest start is attemted.kvm: unhandled validity intercept 0x1011WARNING: CPU: 0 PID: 781237 at arch/s390/kvm/intercept.c:101 kvm_handle_sie_intercept+0x42e/0x4d0 [kvm]Modules linked in: vhost_net tap tun xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT xt_tcpudp nft_compat x_tables nf_nat_tftp nf_conntrack_tftp vfio_pci_core irqbypass vhost_vsock vmw_vsock_virtio_transport_common vsock vhost vhost_iotlb kvm nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 ip_set nf_tables sunrpc mlx5_ib ib_uverbs ib_core mlx5_core uvdevice s390_trng eadm_sch vfio_ccw zcrypt_cex4 mdev vfio_iommu_type1 vfio sch_fq_codel drm i2c_core loop drm_panel_orientation_quirks configfs nfnetlink lcs ctcm fsm dm_service_time ghash_s390 prng chacha_s390 libchacha aes_s390 des_s390 libdes sha3_512_s390 sha3_256_s390 sha512_s390 sha256_s390 sha1_s390 sha_common dm_mirror dm_region_hash dm_log zfcp scsi_transport_fc scsi_dh_rdac scsi_dh_emc scsi_dh_alua pkey zcrypt dm_multipath rng_core autofs4 [last unloaded: vfio_pci]CPU: 0 PID: 781237 Comm: CPU 0/KVM Not tainted 6.10.0-08682-gcad9f11498ea #6Hardware name: IBM 3931 A01 701 (LPAR)Krnl PSW : 0704c00180000000 000003d93deb0122 (kvm_handle_sie_intercept+0x432/0x4d0 [kvm])           R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:3 CC:0 PM:0 RI:0 EA:3Krnl GPRS: 000003d900000027 000003d900000023 0000000000000028 000002cd00000000           000002d063a00900 00000359c6daf708 00000000000bebb5 0000000000001eff           000002cfd82e9000 000002cfd80bc000 0000000000001011 000003d93deda412           000003ff8962df98 000003d93de77ce0 000003d93deb011e 00000359c6daf960Krnl Code: 000003d93deb0112: c020fffe7259	larl	%r2,000003d93de7e5c4           000003d93deb0118: c0e53fa8beac	brasl	%r14,000003d9bd3c7e70          #000003d93deb011e: af000000		mc	0,0          >000003d93deb0122: a728ffea		lhi	%r2,-22           000003d93deb0126: a7f4fe24		brc	15,000003d93deafd6e           000003d93deb012a: 9101f0b0		tm	176(%r15),1           000003d93deb012e: a774fe48		brc	7,000003d93deafdbe           000003d93deb0132: 40a0f0ae		sth	%r10,174(%r15)Call Trace: [<000003d93deb0122>] kvm_handle_sie_intercept+0x432/0x4d0 [kvm]([<000003d93deb011e>] kvm_handle_sie_intercept+0x42e/0x4d0 [kvm]) [<000003d93deacc10>] vcpu_post_run+0x1d0/0x3b0 [kvm] [<000003d93deaceda>] __vcpu_run+0xea/0x2d0 [kvm] [<000003d93dead9da>] kvm_arch_vcpu_ioctl_run+0x16a/0x430 [kvm] [<000003d93de93ee0>] kvm_vcpu_ioctl+0x190/0x7c0 [kvm] [<000003d9bd728b4e>] vfs_ioctl+0x2e/0x70 [<000003d9bd72a092>] __s390x_sys_ioctl+0xc2/0xd0 [<000003d9be0e9222>] __do_syscall+0x1f2/0x2e0 [<000003d9be0f9a90>] system_call+0x70/0x98Last Breaking-Event-Address: [<000003d9bd3c7f58>] __warn_printk+0xe8/0xf0
