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...

CVE-2022-0847

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...

The vulnerability of the `copy_page_to_iter_pipe` and `push_pipe` functions in the Linux operating system allows a hacker to overwrite the contents of page cache for arbitrary files.

The vulnerability of the copypagetoiterpipe and pushpipe functions in the Linux kernel is related to errors in permission storage. Exploiting this vulnerability could allow an attacker to rewrite the contents of page cache for arbitrary files...

Dirty Pipe Linux Privilege Escalation Exploit

Proof of concept for a vulnerability in the Linux kernel existing since version 5.8 that allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. / SPDX-License-Identifier: GPL-2.0 / / Copyright 20...
