"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvmci_host: fix a race condition in vmci_host_poll() causing GPF\n\nDuring fuzzing, a general protection fault is observed in\nvmci_host_poll().\n\ngeneral protection fault, probably for non-canonical address 0xdffffc0000000019: 0000 [#1] PREEMPT SMP KASAN\nKASAN: null-ptr-deref in range [0x00000000000000c8-0x00000000000000cf]\nRIP: 0010:__lock_acquire+0xf3/0x5e00 kernel/locking/lockdep.c:4926\n<- omitting registers ->\nCall Trace:\n <TASK>\n lock_acquire+0x1a4/0x4a0 kernel/locking/lockdep.c:5672\n __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline]\n _raw_spin_lock_irqsave+0xb3/0x100 kernel/locking/spinlock.c:162\n add_wait_queue+0x3d/0x260 kernel/sched/wait.c:22\n poll_wait include/linux/poll.h:49 [inline]\n vmci_host_poll+0xf8/0x2b0 drivers/misc/vmw_vmci/vmci_host.c:174\n vfs_poll include/linux/poll.h:88 [inline]\n do_pollfd fs/select.c:873 [inline]\n do_poll fs/select.c:921 [inline]\n do_sys_poll+0xc7c/0x1aa0 fs/select.c:1015\n __do_sys_ppoll fs/select.c:1121 [inline]\n __se_sys_ppoll+0x2cc/0x330 fs/select.c:1101\n do_syscall_x64 arch/x86/entry/common.c:51 [inline]\n do_syscall_64+0x4e/0xa0 arch/x86/entry/common.c:82\n entry_SYSCALL_64_after_hwframe+0x46/0xb0\n\nExample thread interleaving that causes the general protection fault\nis as follows:\n\nCPU1 (vmci_host_poll) CPU2 (vmci_host_do_init_context)\n----- -----\n// Read uninitialized context\ncontext = vmci_host_dev->context;\n // Initialize context\n vmci_host_dev->context = vmci_ctx_create();\n vmci_host_dev->ct_type = VMCIOBJ_CONTEXT;\n\nif (vmci_host_dev->ct_type == VMCIOBJ_CONTEXT) {\n // Dereferencing the wrong pointer\n poll_wait(..., &context->host_context);\n}\n\nIn this scenario, vmci_host_poll() reads vmci_host_dev->context first,\nand then reads vmci_host_dev->ct_type to check that\nvmci_host_dev->context is initialized. However, since these two reads\nare not atomically executed, there is a chance of a race condition as\ndescribed above.\n\nTo fix this race condition, read vmci_host_dev->context after checking\nthe value of vmci_host_dev->ct_type so that vmci_host_poll() always\nreads an initialized context."
