Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.6.2

Description The issue allows local users to obtain sensitive information from other users' files under specific circumstances. This can happen when the ext4 data=ordered mode is used and a needs-flushing-before-commit list is mishandled. The exploitation involves waiting for a hardware reset, creating a new file, making write system calls, and then reading this file.
