| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbinder: fix race between mmput() and do_exit()\n\nTask A calls binder_update_page_range() to allocate and insert pages on\na remote address space from Task B. For this, Task A pins the remote mm\nvia mmget_not_zero() first. This can race with Task B do_exit() and the\nfinal mmput() refcount decrement will come from Task A.\n\n Task A | Task B\n ------------------+------------------\n mmget_not_zero() |\n | do_exit()\n | exit_mm()\n | mmput()\n mmput() |\n exit_mmap() |\n remove_vma() |\n fput() |\n\nIn this case, the work of ____fput() from Task B is queued up in Task A\nas TWA_RESUME. So in theory, Task A returns to userspace and the cleanup\nwork gets executed. However, Task A instead sleep, waiting for a reply\nfrom Task B that never comes (it's dead).\n\nThis means the binder_deferred_release() is blocked until an unrelated\nbinder event forces Task A to go back to userspace. All the associated\ndeath notifications will also be delayed until then.\n\nIn order to fix this use mmput_async() that will schedule the work in\nthe corresponding mm->async_put_work WQ instead of Task A." |
