kernel: improper initialization of the "flags" member of the new pipe_buffer

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copypagetoiterpipe and pushpipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cach...

ROS-20220314-02

Vulnerability of copypagetoiterpipe and pushpipe functions of Linux kernel is related to errors when saving permissions. Exploitation of the vulnerability could allow an attacker to overwrite the contents of the page cache of arbitrary files...

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
