An infinite-loop flaw was found in the kernel. When a local user calls the sys_writev syscall with a specially crafted sequence of iov structs, the fuse_fill_write_pages kernel function might never terminate, instead continuing in a tight loop. This process cannot be terminated and requires a reboot.
