CVE-2017-7495

Priority
Medium
Description
fs/ext4/inode.c in the Linux kernel before 4.6.2, when ext4 data=ordered
mode is used, mishandles a needs-flushing-before-commit list, which allows
local users to obtain sensitive information from other users' files in
opportunistic circumstances by waiting for a hardware reset, creating a new
file, making write system calls, and reading this file.
Ubuntu-Description
Huang Weller discovered that the ext4 filesystem implementation in the
Linux kernel mishandled a needs-flushing-before-commit list. A local
attacker could use this to expose sensitive information.
