"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: zero ff_effect before compat copy in input_ff_effect_from_user\n\nIn the compat path input_ff_effect_from_user() aliases the caller's\nnative struct ff_effect with the smaller struct ff_effect_compat and\ncopies only the compat sized prefix:\n\n\tcompat_effect = (struct ff_effect_compat *)effect;\n\n\tif (copy_from_user(compat_effect, buffer,\n\t\t\t sizeof(struct ff_effect_compat)))\n\nThe tail of the native structure is never written. Callers pass an\nuninitialized on-stack object, for example evdev_do_ioctl() for\nEVIOCSFF, so those bytes keep their previous stack contents.\ninput_ff_upload() then stores the full native structure in\nff->effects[id], from where a uinput based force feedback daemon can\nread it back via UI_BEGIN_FF_UPLOAD, disclosing kernel stack memory to\nuserspace.\n\nZero the effect before the compat copy."
