CVE-2017-18257

CVE-2017-18257 affects the Linux kernel: the __get_data_block function in fs/f2fs/data.c (before 4.11) can be triggered by crafted open and fallocate calls via an FS_IOC_FIEMAP ioctl, causing local denial of service (integer overflow and loop). Public advisories from Unity Linux, Ubuntu USN-3696-...

kernel: ext4 filesystem page fault race condition with fallocate call.

A flaw was found in the Linux kernel when attempting to "punch a hole" in files existing on an ext4 filesystem. When punching holes into a file races with the page fault of the same area, it is possible that freed blocks remain referenced from page cache pages mapped to process' address space...
