| Description: | The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl. Wei Fang discovered an integer overflow in the F2FS filesystem implementation in the Linux kernel. A local attacker could use this to cause a denial of service.
