  "description": "In the Linux kernel, the following vulnerability has been resolved:  nfs: fix possible null-ptr-deref when parsing param  According to commit \u0022vfs: parse: deal with zero length string value\u0022, kernel will set the param-\u003Estring to null pointer in vfs_parse_fs_string() if fs string has zero length.  Yet the problem is that, nfs_fs_context_parse_param() will dereferences the param-\u003Estring, without checking whether it is a null pointer, which may trigger a null-ptr-deref bug.  This patch solves it by adding sanity check on param-\u003Estring in nfs_fs_context_parse_param().",
