"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: Initialize beyond-EOF page contents before setting uptodate\n\nfuse_notify_store(), unlike fuse_do_readpage(), does not enable page\nzeroing (because it can be used to change partial page contents).\n\nSo fuse_notify_store() must be more careful to fully initialize page\ncontents (including parts of the page that are beyond end-of-file)\nbefore marking the page uptodate.\n\nThe current code can leave beyond-EOF page contents uninitialized, which\nmakes these uninitialized page contents visible to userspace via mmap().\n\nThis is an information leak, but only affects systems which do not\nenable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the\ncorresponding kernel command line parameter)."
