  "description": "In the Linux kernel, the following vulnerability has been resolved:  vmci_host: fix a race condition in vmci_host_poll() causing GPF  During fuzzing, a general protection fault is observed in vmci_host_poll().  general protection fault, probably for non-canonical address 0xdffffc0000000019: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x00000000000000c8-0x00000000000000cf] RIP: 0010:__lock_acquire\u002B0xf3/0x5e00 kernel/locking/lockdep.c:4926 \u003C- omitting registers -\u003E Call Trace:  \u003CTASK\u003E  lock_acquire\u002B0x1a4/0x4a0 kernel/locking/lockdep.c:5672  __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline]  _raw_spin_lock_irqsave\u002B0xb3/0x100 kernel/locking/spinlock.c:162  add_wait_queue\u002B0x3d/0x260 kernel/sched/wait.c:22  poll_wait include/linux/poll.h:49 [inline]  vmci_host_poll\u002B0xf8/0x2b0 drivers/misc/vmw_vmci/vmci_host.c:174  vfs_poll include/linux/poll.h:88 [inline]  do_pollfd fs/select.c:873 [inline]  do_poll fs/select.c:921 [inline]  do_sys_poll\u002B0xc7c/0x1aa0 fs/select.c:1015  __do_sys_ppoll fs/select.c:1121 [inline]  __se_sys_ppoll\u002B0x2cc/0x330 fs/select.c:1101  do_syscall_x64 arch/x86/entry/common.c:51 [inline]  do_syscall_64\u002B0x4e/0xa0 arch/x86/entry/common.c:82  entry_SYSCALL_64_after_hwframe\u002B0x46/0xb0  Example thread interleaving that causes the general protection fault is as follows:  CPU1 (vmci_host_poll)               CPU2 (vmci_host_do_init_context) -----                               ----- // Read uninitialized context context = vmci_host_dev-\u003Econtext;                                     // Initialize context                                     vmci_host_dev-\u003Econtext = vmci_ctx_create();                                     vmci_host_dev-\u003Ect_type = VMCIOBJ_CONTEXT;  if (vmci_host_dev-\u003Ect_type == VMCIOBJ_CONTEXT) {     // Dereferencing the wrong pointer     poll_wait(..., \u0026context-\u003Ehost_context); }  In this scenario, vmci_host_poll() reads vmci_host_dev-\u003Econtext first, and then reads vmci_host_dev-\u003Ect_type to check that vmci_host_dev-\u003Econtext is initialized. However, since these two reads are not atomically executed, there is a chance of a race condition as described above.  To fix this race condition, read vmci_host_dev-\u003Econtext after checking the value of vmci_host_dev-\u003Ect_type so that vmci_host_poll() always reads an initialized context.",
