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." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
